Acarapis Woodi (Rennie) and Varroa Destructor Q
Occurrence Of Honey Bee (Apis mellifera L.) Parasites Acarapis woodi (Rennie) and Varroa destructor Q. In The Region of Muğla, Turkey Msc. Duygu Şimşek*, Prof. Dr. Nevin KESKİN* *Hacettepe University, Department of Biology, Applied Biology Section, Ankara-TURKEY e-mail:[email protected] INTRODUCTION Another mite which causes a disease in adult honeybees is Acarapis woodi. According to the some studies carried in different periods between the years 1988-2003, there is no evidence for A. woodi which has This study was carried out to determine the occurrence of honey bee (Apis mellifera L.) parasites Acarapis been spread out in Balkans in recent years (3, 7). However, this parasite was detected in a country- woodi (Rennie) and Varroa destructor in the province of Muğla which has 17% of the hives and governs %80- wide study which was carried out with molecular techniques by Hacettepe University Bee Health Laboratory in 2005 (12). In this study, there is no evidence for A. woodi existence in samples according to the 85 of the honey export of our country. microscopic(Figure 3) and molecular assays. 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. -

Life History of the Honey Bee Tracheal Mite (Acari: Tarsonemidae)
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). -

PARASITIC MITES OF HONEY BEES: Life History, Implications, and Impact Diana Sammataro1, Uri Gerson2, and Glen Needham3 1Department of Entomology, The Pennsylvania State University, 501 Agricultural Sciences and Industries Building, University Park, PA 16802; e-mail: [email protected] 2Department of Entomology, Faculty of Agricultural, Food and Environmental Quality Sciences, Hebrew University of Jerusalem, Rehovot 76100, Israel; e-mail: [email protected] 3Acarology Laboratory, Department of Entomology, 484 W. 12th Ave., The Ohio State University, Columbus, Ohio 43210; e-mail: [email protected] Key Words bee mites, Acarapis, Varroa, Tropilaelaps, Apis mellifera Abstract The hive of the honey bee is a suitable habitat for diverse mites (Acari), including nonparasitic, omnivorous, and pollen-feeding species, and para- sites. 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. -
Ichneumon Sub-Families This Page Describes the Different Sub-Families of the Ichneumonidae
Ichneumon Sub-families This page describes the different sub-families of the Ichneumonidae. Their ecology and life histories are summarised, with references to more detailed articles or books. Yorkshire species from each group can be found in the Yorkshire checklist. An asterix indicates that a foreign-language key has been translated into English. 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.
