  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Williams Abstract In order to understand any animal and its habitat requirements, we must know what it eats. Reported here are observations of feeding by 27 species of true bugs (Hemiptera: Heteroptera) encountered in various habitats in Wisconsin over the years 2003–2014. This is the first report ofAnasa repetita Heidemann (Coreidae) from Wisconsin. ____________________ Knowing what an animal eats is essential to our understanding of that animal and its habitat requirements. Over the years 2003–2014, I accumulated many observations of insects feeding in Wisconsin. These data are vouchered by hand-collected specimens given to the Insect Research Collection of the Entomology Department at University of Wisconsin - Madison.

  • Fourlined Plant Bug Poecilocapsus Lineatus Order Hemiptera, Family Miridae; Plant Or Leaf Bugs Native Pest
    Pests of Trees and Shrubs Fourlined plant bug Poecilocapsus lineatus Order Hemiptera, Family Miridae; plant or leaf bugs Native pest Host plants: Amur maple, azalea, dogwood, forsythia, rose, viburnum, and approximately 250 other plant species, especially in the mint family. Description: Adult bugs usually have yellow forewings but these may change to bright green. There are four black stripes down the back. Adults are approximately 7 mm long. Larvae vary from red to yellow with black stripes only on the wing buds. Fourlined plant bug adult. (130) Life history: Eggs hatch in late April to May. The nymphal Photo: David Laughlin developmental stage lasts about 30 days. Adults feed on the upper surface of leaves. There is one generation a year. Overwintering: Eggs inserted into a slit near the top of shoots. Damage symptoms: Feeding by both adults and nymphs may cause stippling on leaves—spots of discoloration that may turn from yellow to brown to black. Holes may develop in leaves when heavy infestations occur. Plants are not killed by this insect. Feeding activity ends in early summer. Monitoring: The fourlined plant bug hides under leaves and may be difficult to detect. Look in May and June for signs of stippling on leaves. Net sweeps of foliage may confirm the presence of this insect. Cultural control: Prune perennial plants at ground level to dispose of nymphs. Chemical control: Spray in May and June if feeding damage reaches unacceptable levels. Horticultural oils are effective against nymphs. Biological control: No report of natural enemies. Plant mortality risk: Low Biorational pesticides: azadirachtin, insecticidal soap, pyrethrins Conventional pesticides: acephate, bifenthrin, carbaryl, chlorpyrifos (nursery only), cyfluthrin, deltamethrin, fluvalinate, imidacloprid, lambda-cyhalothrin, malathion, permethrin IPM of Midwest Landscapes 140.

This genus is character- istic in having the large and thick body, the pointed head in front, the incrassate 1st and 2nd antenna1 segments, the tumid scutellum and the rather short legs. Eocalocoris belongs to the tribe Mirini of the subfamily Mirinae, and related to Calocoris Fieber and Parapantilius Reuter in general appearance. This paper reports a unique species of the Miridae from Japan, which represents a new genus and species. This mirid, which is one of the largest species of Japan, exhibits unusual features such as brownish body furnished with two types of hairs and the peculiar male genital structure. This species was once reported as Mirini sp. with Japanese name Futo-mekuragame by Tawara (1977). Before going further the authors wish to express their gratitude to the following entomologists for offering valuable specimens : Dr. T. Ishihara (Ehime Pref.), Dr. H. Hasegawa (Hoya City), Mr. M.

  • A Systematic Study of the Genus Phytocoris Fallén (Heteroptera
    AN ABSTRACT OF THE THESIS OF Gary Michael Stonedahl for the degree of Doctor of Philosophy in Entomology presented on December 9, 1982 Title: A systematic study of the genus Phytocoris Fallen (Heteroptera: Miridae) in western North America Redacted for Privacy Abstract approved: John D. Lattin The western Nearctic species of the genus Phytocoris Fallen were taxonomically revised. Over 15,000 specimens were examined. Information concerning host plant associations and distributions was compiled and summarized for use by future researchers. External morphological features and characters of the male genitalia were used to distinguish species. The genital tubercles above the clasper bases, claspers, and sclerotized process of the vesica were especially useful in this effort. These structures have been illustrated for each of the included species. One-hundred and sixty-two species of Phytocoris are now recognized from western North America. These have been arranged into 20 species-groups ranging in size from two to twenty-two species. The formation of species-groups was based primarily on characters of the male genitalia. Relationships between groups were cladistically analyzed. Forty-four characters of the male genitalia and external morphology were used to determine the final arrangement of species-groups. Forty-six new species are described, and the following synonymies are proposed (senior synonym first): acaciae Knight = minuendus Knight; calli Knight = laticeps Knight; deserticola Knight lineatellus Knight; empirensis Knight m rinconae Knight; fraterculus Van Duzee = westwoodi Bliven; fuscipennis Knight = longirostris Knight; geniculatus Van Duzee = blackwelli Bliven; interspersus Uhler = eurekae Bliven; juniperanus Knight = chiricahuae Knight, flaviatus Knight, santaritae Knight; ketinelbi Bliven = kahtahbi Bliven; knowltoni Knight = albertae Knight, elongatus Knight; maritimus Van Duzee = sequoiae Bliven; neglectus Knight = yuroki Bliven; nigrifrons Van Duzee = abiesi.

EENY-305 Giant Sweetpotato Bug, Spartocera batatas (Fabricius) (Insecta: Hemiptera: Coreidae)1 Susan E. Halbert2 Introduction A large colony of Spartocera batatas (Fabricius) was found in late June 1995 on an Asian cultivar of sweet potatoes (Ipomoea batatas) in Homestead, Florida, by Lynn D. Howerton, environmental specialist, Division of Plant Industry (DPI). The plants were badly damaged by the insects. That collection represented the first report of S. batatas in the continental U.S. Subsequent surveys of commercial fields of sweet potatoes in the area failed to turn up any more S. batatas. However, an Figure 1. Colony of Spartocera batatas (Fabricius), a additional single specimen was found in Miami in sweet potato pest, on sweet potato.

Many bugs were found in suburban Miami by Julieta Brambila (University of Florida, Institute of personal communication). Records from Cuba Food and Agricultural Sciences) in late September indicate apparent range expansion across the island 1996. (Ravelo 1988). It is not known when or how the insect was introduced into Florida, but its limited Distribution distribution suggests that the introduction was recent at that time. Spartocera batatas was described from Surinam and is also found on several of the Caribbean islands. It is considered a minor pest of sweet potatoes in Puerto Rico (A.
