(Hirudinea: Piscicolidae) from the Gills of Spot, Leiostomus xanthurus, in the Lower Chesapeake Bay, Virginia1 EUGENE M. BURRESON AND DENNIS A. TnoNEY2 School of Marine Science, Virginia Institute of Marine Science, College of William and Mary, Gloucester Point, Virginia 23062 ABSTRACT: Aestabdella leiostomi is characterized externally by a subcylindrical to flat, unpigmented body lacking tubercles, gills, and pulsatile vesicles; a large, very deeply cupped caudal sucker and 2 pairs of poorly formed eyes on the oral sucker are present. Internal anatomy is characterized by 2 pairs of esophageal diverticula, 5 pairs of testisacs, large bursa, paired conducting tissue strands connecting copulatory zone and ovisacs, expansive coelomic system lacking testicular sinuses, and 10 pairs of large nephridia. This leech is the first member of the genus from the Atlantic Ocean; it is known only from spot collected during summer from the lower Chesapeake Bay and from the Gulf of Mexico near Pascagoula, Mississippi.

The marine leeches of the east coast of the Materials and Methods United States have been relatively well studied Leeches were collected during summer of 1987 from (Sawyer et al., 1975; Appy and Dadswell, 1981; the gills of spot, Leiostomus xanthurus.

Stomach bot flies (Calyptratae: Oestridae, Gasterophilinae) are obligate endoparasitoids of Proboscidea (i.e. elephants), Rhinocerotidae (i.e. rhinos) and Equidae (i.e. horses and zebras, etc.), with their larvae developing in the digestive tract of hosts with very strong host specificity. They represent an extremely unusual diver- sity among dipteran, or even insect parasites in general, and therefore provide sig- nificant insights into the evolution of parasitism. The phylogeny of stomach botflies was reconstructed

Smith, Plant Pathology Instructor, Plant Health Clinic Diagnostician Letter #6 October 31, 2017 ________________________________________________________________________________ Stopping Occasional Arthropod Invaders John D. Hopkins When the weather begins to change in the fall and things get cooler, arthropod pests like the multi-colored Asian lady beetle, the boxelder bug, crickets, various stinkbugs, or spiders are just some of the pest problems that homeowners may have to deal with. The first thing most people think of when trying to prevent a pest problem is WHAT INSECTICIDE DO I SPRAY? However, there are other measures that should be taken that will help prevent these pests from entering your home and may even eliminate the need for an insecticide application. Pest proofing your home is the BEST way to prevent unwanted invaders at this time or any other time of year. Your goal is to prevent pest entry and eliminate conditions that are conducive to pest infestation. Here are the ABC’s of pest proofing your home: A. Ensure that screens on doors and windows are properly installed and maintained. If you don't have screen doors on your home, install them. Any damaged screens should be repaired or replaced. Fine mesh screening will prevent all but the tiniest insects from entering your home. B. Doors should seal properly. If air can pass through or light can be seen through cracks around doors then insects or spiders can get in.

ABSTRACT FLEAS, HOSTS AND HABITAT: WHAT CAN WE PREDICT ABOUT THE SPREAD OF VECTOR-BORNE ZOONOTIC DISEASES? MEGAN M. FRIGGENS Vector-borne diseases of humans and wildlife are experiencing resurgence across the globe. I examine the dynamics of flea borne diseases through a comparative analysis of flea literature and analyses of field data collected from three sites in New Mexico: The Sevilleta National Wildlife Refuge, the Sandia Mountains and the Valles Caldera National Preserve (VCNP). My objectives were to use these analyses to better predict and manage for the spread of diseases such as plague (Yersinia pestis). To assess the impact of anthropogenic disturbance on flea communities, I compiled and analyzed data from 63 published empirical studies. Anthropogenic disturbance is associated with conditions conducive to increased transmission of flea-borne diseases. Most measures of flea infestation increased with increasing disturbance or peaked at intermediate levels of disturbance. Future trends of habitat and climate change will probably favor the spread of flea-borne disease.

For this, a defi ned number of praeimaginal stages of M. domestica was transferred in daily intervals (from day 0 to day 10) on faecal samples of a naturally infected horse harboring 269 adult H. muscae in its stomach. The development of M. domestica was monitored until imagines appeared. Harvested pupae were measured and weighted and the success of infection was studied by counting 3rd stage nematode larvae in freshly hatched fl ies. In addition, time of pupation and duration of the whole development of the fl ies was noticed. Pupation, hatching and preimaginal mortality rates were calculated and the number of nematode larvae in freshly hatched fl ies was counted. Adult fl ies harboured up to 60 Habronema larvae. Lower pupal volumes and weights, lower pupation rates and higher preimaginal mortality rates were found in experimental groups with long exposure to parasite eggs compared to experimental groups with short exposure or to the uninfected control groups. Maggots of the former groups pupated earlier and fl y imagines occurred earlier. These fi ndings clearly showed a negative impact of H.

  • Life History Notes on the Banded Grass-Skipper, Toxidia Parvulus (Plotz, 1884) Lepidoptera: Hesperiidae - Wesley Jenkinson
    Life History Notes on the Banded Grass-skipper, Toxidia parvulus (Plotz, 1884) Lepidoptera: Hesperiidae - Wesley Jenkinson This hesperiid is one of many small species located throughout the eastern Australian states. Even though the species is quite common locally, any published detail regarding the life history appears to be lacking. In South East Queensland the species is generally more restricted in its habitat range than the common Dingy Grass- skipper (Toxidia peron) and usually avoids suburban gardens (unless suitable habitat exists nearby). It is locally common in the foothills and mountain slopes of the Great Divide, where it is chiefly established in a range of moist and dry eucalypt open forests where suitable host grasses are growing. The adults are slower and less robust in flight than T. peron, and usually remain closer to the ground than other species in the genus, unless searching for flowers. Both sexes are readily attracted to a wide variety of small native and introduced flowers. The average wingspan for the males is 23mm and 24mm for the females. Banded Grass-skipper (Toxidia parvulus) Ovipositing was observed during warm, sunny conditions around midday, during March 2008 in South East Queensland. Females fluttered slowly amongst the host grasses and settled on the stems, laying eggs singly on sheltered parts of the stem. They appeared to have a preference for the softer grass established in semi-shaded areas below large eucalypt trees. After an egg was laid, they flew several metres in search of another suitable location to lay the next egg. While ovipositing, the wings remain closed and the abdomen was curled onto the host plant.

Fleas (Siphonaptera) are Cretaceous, and Evolved with Theria Qiyun Zhu1, Michael Hastriter2, Michael Whiting2, 3, Katharina Dittmar1, 4* Jan. 23, 2015 Abstract: Fleas (order Siphonaptera) are highly-specialized, diverse blood-feeding ectoparasites of mammals and birds with an enigmatic evolutionary history and obscure origin. We here present a molecular phylogenetic study based on a compre- hensive taxon sampling of 259 flea taxa, representing 16 of the 18 extant families of this order. A Bayesian phylogenetic tree with strong nodal support was recovered, consisting of seven sequentially derived lineages with Macropsyllidae at the base and Stephanocircidae as the second basal group. Divergence times of flea lineages were estimated based on fossil records and host specific associations to bats (Chiroptera), showing that the common ancestor of extant Siphonaptera split from its clos- est mecopteran sister group in the Early Cretaceous and basal lineages diversified during the Late Cretaceous. However, most of the intraordinal divergence into families took place after the K-Pg boundary. Ancestral states of host association and bioge- ographical distribution were reconstructed, suggesting with high likelihood that fleas originated in the southern continents (Gondwana) and migrated from South America to their extant distributions in a relatively short time frame. Theria (placental mammals and marsupials) represent the most likely ancestral host group of extant Siphonaptera, with marsupials occupying a more important role than previously assumed.
