In most mosquito species, the females require a blood-feeding for complete egg development. However, in Toxorhynchites mosquitoes, the eggs develop without blood-feeding, and both females and males exclusively feed on sugary diets. The midgut is a well-understood organ in blood-feeding mosquitoes, but little is known about it in non-blood-feeding ones. In the present study, the detailed morphol...

Larvae of Florida Keys Ochlerotatus taeniorhynchus collected from No Name Key were colonized and evaluated against technical S-methoprene in laboratory beaker tests. Glassware was treated with a silanizing reagent before testing to prevent methoprene attachment to the glassware. The No Name Key strain was compared with a susceptible laboratory strain of Oc. taeniorhynchus. Five serial dilutions...

We revised the Euphorinae (Hymenoptera: Braconidae) collected in Reunion Island (Indian Ocean). To date, only Chrysopophthorus hungaricus (Kiss) was reported there. This catalogue is updated to a total of nine species, six of them being newly described: Centistes caloupile sp. nov., Cosmophorus merdiculus sp. nov., Leiophron sarahae sp. nov., Leiophron yaeli sp. nov., Meteorus comonile sp. nov....

The seasonal prevalence and container preferences of Aedes albopictus (Skuse) were studied in the park, Parque Mirador del Norte in Santo Domingo City, Dominican Republic, from January to December 1994. Tire ovitraps were set along a transect through the park and monitored weekly while two larval surveys were conducted in both the park and surrounding houses using standard entomological methodo...

There is currently considerable interest and practical progress in using the endosymbiotic bacteria Wolbachia as a vector control agent for human vector-borne diseases. Such vector control strategies may require the introduction of multiple, different Wolbachia strains into target vector populations, necessitating the identification and characterization of appropriate endosymbiont variants. Her...

The identification of arthropod bloodmeals is important in many epidemiological studies, as, the understanding of the life cycle of vectors and the pathogens they transmit, as well as helping to define arthropods' control strategies. The precipitin test has been used for decades, but ELISA is slowly becoming more popular. To compare the two tests for sensitivity, specificity and accuracy to det...
