Characters for Identifying Common Falimies of Heteroptera (Hemiptera)1 Mesoveliidae: Diagnostic characters: small, elongate; greenish or yellowish; wingless or winged (if winged, clavus of forewing membranous, membrane veinless); antennae long, slender; tarsal claws apical; ocelli present; legs with conspicuous black spines. Water treaders, as members of the neustonic fauna, occur on the surface of standing waters, often among floating or emergent vegetation. They feed as scavengers on dead and dying insects trapped in the surface film. Photo: Mesovelia mulsanti, winged and apterous adults; hind tibia showing black spines. Hydrometridae: Diagnostic characters: small, delicate bugs, with very slender, elongate body; head long and slender; eyes bulging in the middle. Water measurers are also neustonic scavengers and predators, but often go unnoticed because of their very slender bodies. 1 Photos from University of Minnesota Insect Collection (RW Holzenthal). !1 Veliidae: Diagnostic characters: small (less than 5 mm), neustonic bugs; tarsal claws anteapical; hind femora extending little, if any, beyond apex of abdomen. Riffle bugs are commonly found just below the riffles of streams, but also in ponds and lakes. They often occur in large swarms. They prey on other surface dwelling arthropods, detecting their prey through surface vibrations. Photo: Rhagovelia obesa, Minnesota. Gerridae: Diagnostic characters: arger than veliids, also inhabiting the water-surface; tarsal claws anteapical; hind femora extending well beyond apex of abdomen. Water striders are very common surface bugs in lakes, ponds, and pools. They move across the surface of the water by "rowing" and also communicate by tapping the surface with their legs. They prey on insect trapped or living on the surface. Winged and wingless adults occur in some species. All are freshwater inhabitants except for species in the genus Halobates which occur in the open ocean. Photo: Limnoporus dissortis, Minnesota. Saldidae: Diagnostic characters: small, oval, flattened semiaquatic bugs; forewing membrane with 4-5 long closed cells. Shore bugs are active shore inhabiting predatory insects. Photo: Saldula confluenta, Minnesota. Belostomatidae: Diagnostic characters: medium to large; brownish, oval, flat, with strong, raptorial forelegs; short, retractile respiratory appendages at tip of abdomen. Giant water bugs are very common aquatic bugs found in ponds, pools, and ditches. They have a short siphon at the tip of the abdomen used for breathing while they are submerged. They are rapacious predators; the larger species even prey of small fish and frogs. They are good fliers and are attracted to lights at night. They can give a fierce bite if not handled properly. All of these characteristics are captured in their various common names: "fish killers," "toe biters," and "electric light bugs." Photos: Lethocerus americanus, a large giant water bug from Minnesota; Belostoma flumineum, Minnesota, male with eggs on dorsum of hemelytra. !2 Nepidae: Diagnostic characters: slender-elongate or elongate-oval; forelegs slender and raptorial; long, non-retractable breathing tube at tip of the abdomen. Water scorpions live in the same habitats as giant water bugs and are as equally common. They hang from the surface with the tip of their long siphon exposed and grab passing prey with long raptorial forelegs. Photos: Two water scorpions from Minnesota, Ranatra kirkaldyi and Nepa apiculata, representing the two body forms. Gelastocoridae: Diagnostic characters: small, toad-shaped bugs with bulging eyes. Toad bugs could not be more aptly named - their resemblance to toads is remarkable. They also hop and can change color to match the substrate! They live along the shores of ponds, lakes and rivers where they prey on other shore inhabiting arthropods. Photo: Gelastocoris oculatus. Corixidae: Diagnostic characters: front tarsi 1-segmented and scoop- shaped; beak very short and hidden, appearing 1-segmented. Water boatman are very common and abundant in ponds, lakes, pools, and ditches; some species are found in brackish water or in intertidal zones. They use oar-like hind and mid legs for swimming. The mouthparts are adapted for taking in small particles of solid food as well as very small aquatic organisms such as diatoms, protozoans, rotifers and organic material that they sweep into the mouth with the scoop-shaped fore tarsi; others are herbivorous and puncture the cells of filamentous algae while a few prey on mosquito larvae. The males have asymmetrical genitalia and modified pegs on the fore femora for stridulation against the sharp sides of the head. Photos: Hesperocorixa laevigata, Minnesota. Head of H. lobata, showing broad, conical beak and modified fore tarsus. !3 Naucoridae: Diagnostic characters: small, oval, with flattened body, somewhat similar to belostomatids but with front femora greatly enlarged. Creeping water bugs, or gator fleas, occur in rivers and ponds. Some lotic species are adapted to fast flowing areas, while the lentic species occur among vegetation. They can inflict a very painful bite when handled. They breathe under water by way of a "plastron gill," a region of very dense hairs on the body surface that traps a layer of air across which oxygen and carbon dioxide diffuse. Photo: A creeping water bug from Arizona. Notonectidae: Diagnostic characters: similar to corixids but convex and with front tarsi unmodified; beak more elongate and segmented. Backswimmers occur in standing waters where they swim upside down in the water column in search of prey, often by sneaking up on them from below. Males also stridulate by rubbing the fore legs against the beak. They also bite! Photo: Notonecta insulata, Minnesota. Pleidae: Diagnostic characters: small (3 mm or less), oval; similar to notonectids, but much smaller, with much more convex body. Pygmy backswimmers are very common and abundant in weedy ponds in Minnesota, but often go unnoticed because of their small size. They carry a bubble of air on their ventral surface for respiration as they crawl around in vegetation in search of their prey, aquatic micro-arthropods. Photo: A pygmy backswimmer from Texas. Cimicidae: Diagnostic characters: flat, oval, less than 6 mm, wings vestigial. This is an annoying pest that has become more commonly encountered in recent years, especially in hotels, motels, and apartment buildings. The bugs hide in crack and crevices during the day. At night they leave their retreats to feed on unsuspecting guests. They do not vector disease, but cause an irritating bite. Adults can live for several months with out a meal. Photo: The common bed bug, Cimex lectularius, Minnesota. Anthocoridae: Diagnostic characters: small, about 3-5 mm, somewhat oval, flattened, black with white markings; hemelytra with a cuneus; beak 3-segmented. Photo: A minute pirate bug, Minnesota. These tiny bugs commonly occur on flowers and fruit where they feed on insect eggs and small insects. One species, the insidious flower bug, packs a powerful bite for its small size. !4 Reduviidae: Diagnostic characters: body generally elongate oval, rarely greatly elongate; beak short, 3-segmented, its tip fitting into a stridulatory groove in the prosternum; head elongate with part behind the eyes neck-like; transverse groove between the eyes. The assassin bugs constitute a large, diverse family of highly predaceous bugs; members of the subfamily Triatominae bite humans and other vertebrates for a blood meal. Photos: Species of Triatoma, or "kissing bugs," of the Neotropics transmit Chagas disease, caused by the protozoan Trypanosoma cruzi. The masked hunter is a species that preys on bedbugs. Photos: The wheel bug, Arilus cristata, ventral view of head, showing beak and prosternal groove. Several examples of Neotropical species from Costa Rica 1, 2, and Peru 3, 4. Reduviidae: Phymatinae: Diagnostic characters: front femora greatly thickened; abdomen wider in distal half, extending laterally beyond wings. Ambush bugs are common, easily recognized, cryptically colored predators, now included within the Reduviidae as a subfamily. They are common on goldenrod where they blend in perfectly. They capture other insects, even larger bees, wasps, and flies, that visit flowers during pollination. Photo: Phymata pennsylvanica, Minnesota, dorsal and lateral. !5 Miridae: Diagnostic characters: small,10 mm or less, oval or elongate; hemelytra with cuneus, membrane with 1 or 2 closed cells. These are very common and abundant bugs found on plants. Most are plant feeders and many of these are of economic importance; others are predaceous. Photos: Coquillettia mimetica, adult and ant mimicking nymph, Minnesota; the four-lined plant bug, Poecilopsus lineatus, Minnesota. Nabidae: Diagnostic characters: elongate, oval; ocelli present; prothoracic legs with femora slightly thickened; membrane of hemelytra with numerous marginal cells. These predaceous little bugs, the damsel bugs, are important members of the predator community of natural as well as agricultural ecosystems. Photos: Nabis americoferus, adult and detail of foreleg, and the ant mimicking nymph of Nabis flavomarginatus. Tingidae: Diagnostic characters: body and wings with reticulate sculpturing (giving it a "lacy" look). Lace bugs are known for the remarkable ornamentation of the cuticle of the adult. They are plant feeders and when in great abundance their feeding can can damage plants, especially trees. Photo: Corythuca heidemanni, Minnesota. !6 Aradidae: Diagnostic characters: small, dark, very flat, oval; wings narrow,

    Morphology and Adaptation of Immature Stages of Hemipteran Insects

    © 2019 JETIR January 2019, Volume 6, Issue 1 www.jetir.org (ISSN-2349-5162) Morphology and Adaptation of Immature Stages of Hemipteran Insects Devina Seram and Yendrembam K Devi Assistant Professor, School of Agriculture, Lovely Professional University, Phagwara, Punjab Introduction Insect Adaptations An adaptation is an environmental change so an insect can better fit in and have a better chance of living. Insects are modified in many ways according to their environment. Insects can have adapted legs, mouthparts, body shapes, etc. which makes them easier to survive in the environment that they live in and these adaptations also help them get away from predators and other natural enemies. Here are some adaptations in the immature stages of important families of Hemiptera. Hemiptera are hemimetabolous exopterygotes with only egg and nymphal immature stages and are divided into two sub-orders, homoptera and heteroptera. The immature stages of homopteran families include Delphacidae, Fulgoridae, Cercopidae, Cicadidae, Membracidae, Cicadellidae, Psyllidae, Aleyrodidae, Aphididae, Phylloxeridae, Coccidae, Pseudococcidae, Diaspididae and heteropteran families Notonectidae, Corixidae, Belastomatidae, Nepidae, Hydrometridae, Gerridae, Veliidae, Cimicidae, Reduviidae, Pentatomidae, Lygaeidae, Coreidae, Tingitidae, Miridae will be discussed. Homopteran families 1. Delphacidae – Eg. plant hoppers They comprise the largest family of plant hoppers and are characterized by the presence of large, flattened spurs at the apex of their hind tibiae. Eggs are deposited inside plant tissues, elliptical in shape, colourless to whitish. Nymphs are similar in appearance to adults except for size, colour, under- developed wing pads and genitalia. 2. Fulgoridae – Eg. lantern bugs They can be recognized with their antennae inserted on the sides & beneath the eyes.

Yoshifumi Touyama1, Fuminori Ito2 1Niho, Minami-ku, Hiroshima City, Japan 2Laboratory of Entomology, Faculty of Agriculture, Kagawa University, Ikenobe, Japan Email: [email protected] Received 23 April 2014; revised 3 June 2014; accepted 22 June 2014 Copyright © 2014 by authors and Scientific Research Publishing Inc. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Argentine ant invasion changed colour-polymorphic composition of ant-mimetic jumping spider Myrmarachne in southwestern Japan. In Argentine ant-free sites, most of Myrmarachne exhibited all-blackish colouration. In Argentine ant-infested sites, on the other hand, blackish morph de- creased, and bicoloured (i.e. partly bright-coloured) morphs increased in dominance. Invasive Argentine ant drives away native blackish ants. Disappearance of blackish model ants supposedly led to malfunction of Batesian mimicry of Myrmarachne. Keywords Batesian Mimicry, Biological Invasion, Linepithema humile, Myrmecomorphy, Myrmarachne, Polymorphism 1. Introduction It has attracted attention of biologists that many arthropods morphologically and/or behaviorally resemble ants [1]-[4]. Resemblance of non-ant arthropods to aggressive and/or unpalatable ants is called myrmecomorphy (ant-mimicry). Especially, spider myrmecomorphy has been described through many literatures [5]-[9]. Myr- mecomorphy is considered to be an example of Batesian mimicry gaining protection from predators.

    The Corixidae (Hemiptera) of Oklahoma KURT F

    BIOLOGICAL SCIENCES 71 The Corixidae (Hemiptera) of Oklahoma KURT F. SCHAEFER, Panhandle State Colle.e, Goodwell The Corixidae or water boatman family is a commonly collected fam­ ily taken in a variety of aquatic habitats and frequently at lights at night or on shiny surfaces during the day. Hungerford's 1948 monograph on the world corixids is an important contribution, essential to a serious collector. My paper is an attempt to make the identification of state fonns easier and to supply descriptions and distribution data for the corixids of the state. Schaefer and Drew (1964) reported 18 species and Ewing (1964) added one for the state. Five addi­ tional species are included because information of their known ranges in­ dicates that they will probably be found in Oklahoma when more collecting is done. Each pair of legs is modified for a different function. The anterior pair is short with the tenninal segment (pala) often more or less spoon­ shaped and fringed with bristles for food gathering. Both adults and nymphs feed mainly on algae and protozoa, obtained from bottom ooze (Usinger, 1956). The middle pair of legs, used for anchorage and support, is long and slender, tenninating with two long claws. The hind pair, for swimming, is stouter, laterally flattened and fringed with hairs. The principal dimorphic structures used as key characters are as fol­ lows: males, usually smaller, with vertex of the head otten more produced and frons concavely depressed. Fonn and chaetotaxy of the male palae, front tarsi, are much used characters. The female abdomen is bilaterally symmetrical, while the asymmetry of male may be either to the right (dextral) or left (stnistral).

Tuan, PhD* Department of Agricultural Sciences, College of Agriculture, Fisheries, and Natural Resources University of Eastern Philippines, University Town, Catarman, Northern Samar, Philippines Abstract A field experiment was conducted to evaluate the incidence of Rice bug, Leptocorisaoratorius(F.) using B. bassiana as mycoinsectice under upland conditions. Field population of L. oratorius was not significantly affected by B. bassiana7 DAS, but significant at 15 DAS. The application of B. bassiana did not significantly affect the damage caused by L. oratoriuson rice grains.The results suggest that B. bassiana cannot be used as a sole mortality factor in the management of rice bug under upland conditions. More field experimentations are necessary taking into consideration the influence of environmental factors and how these can be manipulated in favor of the fungal insecticide. Key Words: Conidia, substrate, microbial insecticide, upand rice, abiotic environmental factors INTRODUCTION Rice bug, Leptrocorisaoratorius (F.) is one of the major insect pests infesting rice in upland areas. Several species of rice bugs occur in the Philippines, but L. oratorius is the most prevalent (Reissig et al., 1986; Litsinger et al., 1987). Upland rice is usually cultivated for organic rice or with less application of fertilizer and pesticides. The increasing demand for organically produced foods including rice, has contributed to the adoption of ecologically oriented pest control methods. Consequently, reduced pesticide use has become a strong option to protect the environment and human health.

    Broad-Headed Bugs (Alydidae)

    Chapter 18 Broad-Headed Bugs (Alydidae) Antônio R. Panizzi and Carl w. Schaefer Abstract The broad-headed bugs (Alydidae) are divided into two subfamilies, Alydinaeand Micrelytrinae, each divided into two tribes, Daclerini and Alydini, and Micrelytriniand Leptocorisini, respectively, The farnily has 53 genera and about 250 specieins; the Neotropics, there are 21 genera. Alydids are small (8-20 mm), slen- Itr,with a triangular head; nymphs of alydines mimic ants, the adults of some Micrelytrinialso rnirnic ants. The most studied species in the Neotropics is the aly- dineNeomegalotomus parvus (Westwood), usually associated with legumes, and maybe a pest on soybean. Other common genera include Hyalymenus Amyot & Serville,Stenocoris Burmeister, Cydamus Stâl, and Trachelium Herrich-Schâffer. Studieson taxonomy and bioecology on alydids of the Neotropics are needed. 18.1 Introduction AlydidaeAmyot and Serville, 1843, were treated as a subfarnily of the farnily Coreidaeand even as a tribe (Schaffner 1964); now it has been treated as a farnily, ~ether with Coreidae, Rhopalidae, Hyocephalidae, and Stenocephalidae, in the !UperfarniCoreoidealy (Schaefer 1964). Thisfarnily contains 53 genera and approximately 250 species, mostly tropical Irsubtropical,in all regions of the world. There are only two genera that span both dleOldand the New World, Alydus and Megalotomus. These genera are Holarctic, IInAlydus extends from Alaska through Canada into Mexico (Brailovsky and Flores 1979;Froeschner 1988; Maw et al. 2000). The genera of Alydinae have been revised by Schaffner (1964; 22 species worldwide);the world genera of the subfamily Micrelytrinae, tribe Leptocorisini, were CarlW.Schaefer: Author deceased at the time of publication A.RP.anizzi ([gJ) Laboratóriode Entomologia, Embrapa Trigo, Caixa Postal 3081, Passo Fundo, RS9900l-970,Brazil e-mail:[email protected] eSpringerScience-Business Media Dordrecht 2015 537 :I.R.Panizzi,J.
