EENY-170 Ladybirds, Ladybird beetles, Lady Beetles, Ladybugs of Florida, Coleoptera: Coccinellidae1 J. H. Frank R. F. Mizell, III2 Introduction Ladybird is a name that has been used in England for more than 600 years for the European beetle Coccinella septempunctata. As knowledge about insects increased, the name became extended to all its relatives, members of the beetle family Coccinellidae. Of course these insects are not birds, but butterflies are not flies, nor are dragonflies, stoneflies, mayflies, and fireflies, which all are true common names in folklore, not invented names. The lady for whom they were named was "the Virgin Mary," and common names in other European languages have the same association (the German name Marienkafer translates Figure 1. Adult Coccinella septempunctata Linnaeus, the to "Marybeetle" or ladybeetle). Prose and poetry sevenspotted lady beetle. Credits: James Castner, University of Florida mention ladybird, perhaps the most familiar in English being the children's rhyme: Now, the word ladybird applies to a whole Ladybird, ladybird, fly away home, family of beetles, Coccinellidae or ladybirds, not just Your house is on fire, your children all gone... Coccinella septempunctata. We can but hope that newspaper writers will desist from generalizing them In the USA, the name ladybird was popularly all as "the ladybird" and thus deluding the public into americanized to ladybug, although these insects are believing that there is only one species. There are beetles (Coleoptera), not bugs (Hemiptera). many species of ladybirds, just as there are of birds, and the word "variety" (frequently use by newspaper 1.

Impact of Different Carbon Dioxide Concentrations in the Olfactory Response of Sipha Flava (Hemiptera: Aphididae) and Its Predators
J Insect Behav (2014) 27:722–728 DOI 10.1007/s10905-014-9463-3 Impact of Different Carbon Dioxide Concentrations in the Olfactory Response of Sipha flava (Hemiptera: Aphididae) and its Predators Marcy G. Fonseca & Dayane R. Santos & Alexander M. Auad Revised: 6 August 2014 /Accepted: 8 August 2014 / Published online: 27 August 2014 # Springer Science+Business Media New York 2014 Abstract The increasing level CO2 may altered host plant physiology and hence affect the foraging behavior of herbivore insects and predator. Hence, the aim of this study was provides evidence that host plants grown at different levels of CO2 can alter the choice behavior of aphid, Sipha flava and their natural enemies, Cycloneda sanguinea and Diomus seminulus. The plant used was Pennisetum purpureum,cultivarCameron Piracicaba growing in greenhouse (mean value of CO2=440 ppm), climatic chamber with constant value of CO2=500 ppm and climatic chamber with fluctuating CO2 (mean value=368 ppm). A glass Y-shape olfactometer was used to verify the insects responses towards elephant grass plants cultivated under different conditions. The aphids were statistically more attracted by plants grown with constant CO2 level (500 ppm) than by plants grown with fluctuating CO2 level or plants grown in greenhouse. There was no difference in S. flava preference to non-infested versus infested plants by conspecifics. The predator C. sanguinea did not show difference between plants grown with constant CO2 level and infested or not with S. flava. However, the predator D. seminulus showed higher preference to plants grown with constant CO2 level and infested with S. flava.

Dissertation Advisor: Professor Donald H. Pfister Danny Haelewaters STUDIES OF THE LABOULBENIOMYCETES: DIVERSITY, EVOLUTION, AND PATTERNS OF SPECIATION ABSTRACT CHAPTER 1: Laboulbeniales is one of the most morphologically and ecologically distinct orders of Ascomycota. These microscopic fungi are characterized by an ectoparasitic lifestyle on arthropods, determinate growth, lack of asexual state, high species richness and intractability to culture. DNA extraction and PCR amplification have proven difficult for multiple reasons. DNA isolation techniques and commercially available kits are tested enabling efficient and rapid genetic analysis of Laboulbeniales fungi. Success rates for the different techniques on different taxa are presented and discussed in the light of difficulties with micromanipulation, preservation techniques and negative results. CHAPTER 2: The class Laboulbeniomycetes comprises biotrophic parasites associated with arthropods and fungi.

Volatile infochemicals generated by aphids, their host plants, or from the interaction between host plant and herbivore (herbivore-induced volatile plant compounds) are among the environmental stimuli used by predators to locate prey. The objective of this study was to evaluate the olfactometric response of the predator Cycloneda sanguinea (Coleoptera: Coccinellidae) to volatile infochemicals associated with the tomato plant, Lycopersicon esculentum Mill. (Solanaceae), and the aphid prey Myzus persicae Sulzer (Hemiptera: Aphididae). Predator behavior was evaluated in an airﬂ ow olfactometer at 24 ± 2ºC with 65 ± 10% relative humidity and a 16 h photoperiod. Latency time and the number of visits to the active chamber where the odor source was located were recorded. The odor sources studied were: a. thirty healthy aphids; b. uninfested tomato leaves; c. infested tomato with 30 healthy aphids; d. infested tomato leaves with 30 stressed aphids; e. thirty stressed aphids. C. sanguinea adults were strongly attracted to the odors of infested tomato leaves, but for the other odor sources, they did not visit active chambers more often than inactive chambers.

COLEOPTERA COCCINELLIDAE) INTRODUCTIONS and ESTABLISHMENTS in HAWAII: 1885 to 2015
AN ANNOTATED CHECKLIST OF THE COCCINELLID (COLEOPTERA COCCINELLIDAE) INTRODUCTIONS AND ESTABLISHMENTS IN HAWAII: 1885 to 2015 JOHN R. LEEPER PO Box 13086 Las Cruces, NM USA, 88013 [email protected] [1] Abstract. Blackburn & Sharp (1885: 146 & 147) described the first coccinellids found in Hawaii. The first documented introduction and successful establishment was of Rodolia cardinalis from Australia in 1890 (Swezey, 1923b: 300). This paper documents 167 coccinellid species as having been introduced to the Hawaiian Islands with forty-six (46) species considered established based on unpublished Hawaii State Department of Agriculture records and literature published in Hawaii. The paper also provides nomenclatural and taxonomic changes that have occurred in the Hawaiian records through time. INTRODUCTION The Coccinellidae comprise a large family in the Coleoptera with about 490 genera and 4200 species (Sasaji, 1971). The majority of coccinellid species introduced into Hawaii are predacious on insects and/or mites. Exceptions to this are two mycophagous coccinellids, Calvia decimguttata (Linnaeus) and Psyllobora vigintimaculata (Say). Of these, only P. vigintimaculata (Say) appears to be established, see discussion associated with that species’ listing. The members of the phytophagous subfamily Epilachninae are pests themselves and, to date, are not known to be established in Hawaii. None of the Coccinellidae in Hawaii are thought to be either endemic or indigenous. All have been either accidentally or purposely introduced. Three species, Scymnus discendens (= Diomus debilis LeConte), Scymnus ocellatus (=Scymnobius galapagoensis (Waterhouse)) and Scymnus vividus (= Scymnus (Pullus) loewii Mulsant) were described by Sharp (Blackburn & Sharp, 1885: 146 & 147) from specimens collected in the islands. There are, however, no records of introduction for these species prior to Sharp’s descriptions.

Is the Multicolored Asian Ladybeetle, Harmonia Axyridis, the Most Abundant Natural Enemy to Aphids in Agroecosystems?
Journal of Insect Science: Vol. 13 | Article 158 Vandereycken et al. Is the multicolored Asian ladybeetle, Harmonia axyridis, the most abundant natural enemy to aphids in agroecosystems? Axel Vandereycken1a*, Delphine Durieux1b, Emilie Joie1c, John J. Sloggett2d, Eric Haubruge1e, François J.

Box 616, 6200 MD Maastricht, The Netherlands Downloaded from Abstract The multicolored Asian ladybeetle, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), was introduced into Western Europe in the late 1990s. Since the late 2000s, this species has been http://jinsectscience.oxfordjournals.org/ commonly considered one of the most abundant aphid predators in most Western European coun- tries. In spite of the large amount of research on H. axyridis, information concerning its relative abundance in agroecosystems is lacking. This study aims to evaluate the abundance of H. axyridis within the aphidophage community in four crops situated in southern Belgium: wheat, Triticum aestivum L. (Poales: Poaceae), corn, Zea mays, potato, Solanum tuberosum (Solanales: Solanaceae), and broad bean Vicia faba (Fabales: Fabaceae). In order to assess the species diver- sity, the collected data were analyzed by considering (1) the species richness and (2) the evenness according to the Shannon diversity index. Eleven aphidophages were observed in every invento- ried agroecosystem, including five abundant species: three coccinellids, the seven-spotted by guest on June 2, 2015 ladybug, Coccinella septempunctata L. (Coleoptera: Coccinellidae), the 14-spotted Ladybird, Propylea quatuordecimpunctata, and H. axyridis; one hoverfly, the marmalade hoverfly, Episyr- phus balteatus De Geer (Diptera: Syrphidae); and one lacewing, the common green lacewing, Chrysoperla carnea Stephens sensu lato (= s.l.)

Arthropods of Elm Fork Preserve
Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux.
