The Michigan Entomological Society 1995 THE GREAT LAKES ENTOMOlOGIST 199 TEMPERATURE EFFECTS ON DEVELOPMENT OF THREE CEREAL APHID PARASITOIDS (HYMENOPTERA: APHIDIIDAE) N. C. Elliott1, J. D. Burd, S. D. Kindler, and J. H. lee ABSTRACT Temperature is an important climatological variable that influences the biology and ecology of insects. Poor climatic adaptation can limit the effec­ tiveness of parasitic insects in biological control. Two exotic parasites (Syrian Diaeretiella rapae (M'Intosh) and Argentinean Aphidius colemani Viereck) imported for biological control of the Russian wheat aphid, Diuraphis noxia (Mordvilko), and one native parasite (Diaeretiella rapae) were reared in growth chambers in three fluctuating temperature regimes with average daily temperatures of 12, 18, and 24°C. Estimates of temperature thresholds for immature development were 3.3, 3.5, and 2.8°C, for Oklahoman D. rapae, Syrian D. rapae, and A. colemani, respectively. Estimates of thermal require­ ments for development from egg to adult were 297, 278, and 301 degree-days for the three parasitoids. Dry weights of adults reared in different fluctuating temperature regimes did not differ significantly among sexes, but adults from regimes with low average temperatures of 12 and 18°C had significantly greater weights than those reared in a regime with an average temperature of 24°C. Results suggest that developmental response to temperature will not limit the effectiveness of the exotic parasites in biological control. Diaeretiella rapae M' Intosh is a cosmopolitan aphidiid that commonly parasitizes a wide range of hosts in agroecosystems (Mackauer and Stary 1967). Aphidius colemani Viereck is widely distributed in the southern hemi­ sphere and broadly oligophagous on Aphididae (Stary 1975). Both species par­ asitize several economically important aphid pests of small grain crops in­ cluding the greenbug, Schizaphis graminum (Rondani), and Russian wheat aphid, Diuraphis noxia (Mordvilko) (Mackauer and Stary 1967, Stary 1975). Both A. colemani and D. rapae were imported into the United States for clas­ sical biological control of the Russian wheat aphid in the Southern Great Plains and elsewhere in the western US (Gould and Prokrym 1994). Temperature is an important abiotic variable that influences insect popu­ lations in the field. Temperature can influence insect population growth through its effects on development rate, survival, fecundity, and dispersal (Ratte 1984, Rankin and Singer 1984). Temperature may partially determine the effectiveness of a parasitoid as a biological control agent in a particular re­ gion. For example, a parasitoid with a higher developmental threshold tem­ perature than its host may have limited effectiveness in regions where tem­ peratures below the parasitoids developmental threshold but above the hosts 1 USDA, ARS, SPA, Plant Science Research Laboratory, 1301 N. Western St., Still­ water, OK 74075. 200 THE GREAT LAKES ENTOMOLOGIST Yol. 28, No.3 & 4 threshold occur often, because development from birth to maturity, and hence population growth rate would lag behind that of its host (Campbell et al. 1974). Thus, in addition to factors such as searching ability, host preference, and host suitability, knowledge of developmental responses to temperature should be considered when deciding whether to release an exotic parasitoid for biological control (Bernal and Gonzalez 1993). Estimates of developmental thresholds for D. rapae populations from dif­ ferent regions range from 2.1 to 7.0'C (Campbell et al. 1974, Bernal and Gon­ zalez 1993). The estimates may result from adaptation to geographic differ­ ences in climate (Campbell et al. 1974). To the best of our knowledge, the developmental threshold of A. colemani has not been reported. The first ob­ jective of this study was to determine developmental thresholds and temper­ ature requirements for development of three cereal aphid parasitoids. Two of the parasitoids were imported into the US; Diaeretiella rapae was imported from Syria, while A. colemani was imported from Argentina. A native Okla­ homa population of D. rapae was also examined. Because this parasitoid is en­ demic to the Southern Great Plains, and presumably well adapted to the cli­ mate there, estimation of temperature effects on its development

Varroa destructor Q (Acari, Varroidae) is a haemolymph-sucking parasite of European honey bees (9). The parasite may directly (haemolymph-sucking) and indirectly (as a vector of bacterial, fungal and viral diseases) affect the type and prevalence of honey bee pathogens causing mortality in infested colonies (2). It can be found on adult bees, on the brood and in hive debris. Adult females are a reddish colored oval-flat bodied and measured 1.1 mm long x 1.5 mm wide.

  • ELIZABETH LOCKARD SKILLEN Diversity of Parasitic Hymenoptera
    ELIZABETH LOCKARD SKILLEN Diversity of Parasitic Hymenoptera (Ichneumonidae: Campopleginae and Ichneumoninae) in Great Smoky Mountains National Park and Eastern North American Forests (Under the direction of JOHN PICKERING) I examined species richness and composition of Campopleginae and Ichneumoninae (Hymenoptera: Ichneumonidae) parasitoids in cut and uncut forests and before and after fire in Great Smoky Mountains National Park, Tennessee (GSMNP). I also compared alpha and beta diversity along a latitudinal gradient in Eastern North America with sites in Ontario, Maryland, Georgia, and Florida. Between 1997- 2000, I ran insect Malaise traps at 6 sites in two habitats in GSMNP. Sites include 2 old-growth mesic coves (Porters Creek and Ramsay Cascades), 2 second-growth mesic coves (Meigs Post Prong and Fish Camp Prong) and 2 xeric ridges (Lynn Hollow East and West) in GSMNP. I identified 307 species (9,716 individuals): 165 campoplegine species (3,273 individuals) and a minimum of 142 ichneumonine species (6,443 individuals) from 6 sites in GSMNP. The results show the importance of habitat differences when examining ichneumonid species richness at landscape scales. I report higher richness for both subfamilies combined in the xeric ridge sites (Lynn Hollow West (114) and Lynn Hollow East (112)) than previously reported peaks at mid-latitudes, in Maryland (103), and lower than Maryland for the two cove sites (Porters Creek, 90 and Ramsay Cascades, 88). These subfamilies appear to have largely recovered 70+ years after clear-cutting, yet Campopleginae may be more susceptible to logging disturbance. Campopleginae had higher species richness in old-growth coves and a 66% overlap in species composition between previously cut and uncut coves.

A list of 311 species of flower visitors was dominated by Hymenoptera (121 spp.), Diptera (117 spp.), and Coleoptera (52 spp.). Of 228 species whose diets are known, 158 are predators, 47 are phytophagous, and 44 are decomposers. Many species that visited S. repens flowers also visited flowers of other species at the Archbold Biological Station. The total number of known insect-flower relation- ships that include S. repens is 2,029. There is no evidence of oligolectic species that are de- pendent on saw palmetto flowers. This study further emphasizes the ecological importance and conservation value of S. repens.

Entomologie, Rosenstein 1, D-70191 Stuttgart, Germany Received 19 May 2007; received in revised form 2 August 2007; accepted 22 August 2007 Abstract The phylogenetic diversification of Hexapoda is still not fully understood. Morphological and molecular analyses have resulted in partly contradicting hypotheses. In molecular analyses, 18S sequences are the most frequently employed, but it appears that 18S sequences do not contain enough phylogenetic signals to resolve basal relationships of hexapod lineages. Until recently, character interdependence in these data has never been treated seriously, though possibly accounting for the occurrence of biased results. However, software packages are readily available which can incorporate information on character interdependence within a Bayesian approach. Accounting for character covariation derived from a hexapod consensus secondary structure model and applying mixed DNA/RNA substitution models, our Bayesian analysis of 321 hexapod sequences yielded a partly robust tree that depicts many hexapod relationships congruent with morphological considerations. It appears that the application of mixed DNA/RNA models removes many of the anomalies seen in previous studies. We focus on basal hexapod relationships for which unambiguous results are missing.

    ARTHROPOD BIOLOGY Life History of the Honey Bee Tracheal Mite (Acari: Tarsonemidae) JEFFERY S. PETTIS1 AND WILLIAM T. WILSON Honey Bee Research Unit, USDA-ARS, 2413 East Highway 83, Weslaco, TX 78596 Ann. Entomol. Soc. Am. 89(3): 368-374 (1996) ABSTRACT Data on the seasonal reproductive patterns of the honey bee tracheal mite, Acarapis woodi (Rennie), were obtained by dissecting host honey bees, Apis mellifera L., at intervals during their life span. Mite reproduction normally was limited to 1 complete gen- eration per host bee, regardless of host life span. However, limited egg laying by foundress progeny was observed. Longer lived bees in the fall and winter harbored mites that reproduced for a longer period than did mites in bees during spring and summer. Oviposition rate was relatively uniform at =0.85 eggs per female per day during the initial 16 d of adult bee life regardless of season. In all seasons, peak mite populations occurred in bees =24 d old, with egg laying declining rapidly beyond day 24 in spring and summer bees but more slowly in fall and winter bees. Stadial lengths of eggs and male and female larvae were 5, 4, and 5 d, respectively. Sex ratio ranged from 1.15:1 to 2.01:1, female bias, but because males are not known to migrate they would have been overestimated in the sampling scheme. Fecundity was estimated to be =21 offspring, assuming daughter mites laid limited eggs in tracheae before dispersal. Mortality of adult mites increased with host age; an estimate of 35 d for female mite longevity was indirectly obtained.

OVERWINTERING PERFORMANCE OF HONEY BEE COLONIES HEAVILY INFESTED WITH ACARAPIS WOODI (RENNIE) Frank A. EISCHEN Department of Entomology, University of Georgia, Athens, Georgia 30602 SUMMARY Three groups of honey bee colonies (N = 30) were overwintered on a mountainside (2800 M) in northeastern Mexico. Infestation levels of Acarapis woodi in the three groups averaged 0, 28.2 and 86.0 % for the control, moderately, and heavily infested colonies, respectively. Heavily infested colonies were 28 % smaller than controls (P < 0.01) in the fall. Adjusting for this, heavily infested colonies lost significantly more bees than either the moderately infested group, or the controls (P < 0.0001). Both the moderately and heavily infested groups of bees had less brood than controls at the end of the test (P < 0.02 and P < 0.01 respectively).

The biology and damage of the three main pest species Acarapis woodi, Varroa jacobsoni, and Tropilaelaps clareae is reviewed, along with detection and control methods. The hypothesis that Acarapis woodi is a recently evolved species is rejected. Mite-associated bee pathologies (mostly viral) also cause increasing losses to apiaries. Future studies on bee mites are beset by three main problems: (a) The recent discovery of several new honey bee species and new bee-parasitizing mite species (along with the probability that several species are masquerading under the name Varroa jacob- soni) may bring about new bee-mite associations and increase damage to beekeeping; (b) methods for studying bee pathologies caused by viruses are still largely lacking; (c) few bee- and consumer-friendly methods for controlling bee mites in large apiaries are available.

One method by which the caterpillars of moths and sawflies which are the hosts of these insects attempt to prevent parasitism is for them to hide under leaves during the day and emerge to feed at night. A number of ichneumonoids, spread through several subfamilies of both ichneumons and braconids, exploit this resource by hunting at night. Most ichneumonoids are blackish, which makes them less obvious to predators, but colour is not important in the dark and many of these nocturnal ones have lost the melanin that provides the dark colour, so they are pale orange. They have often developed the large-eyed, yellowish-orange appearance typical of these nocturnal hunters and individuals are often attracted to light. This key to British species is a draft: http://www.nhm.ac.uk/resources-rx/files/keys-for-nocturnal-workshop-reduced-109651.pdf Subfamily Pimplinae. The insects in this subfamily are all elongate and range from robust, heavily- sculptured ichneumons to slender, smooth-bodied ones. Many of them have the 'normal' parasitoid life-cycle (eggs laid in or on the host larvae, feeding on the hosts' fat bodies until they are full- grown and then killing and consuming the hosts) but there are also some variations within this subfamily.
