Mass production is an important co mponent of any pest or vector control program that requires the release of large number of insects. As part of efforts to develop an area-wide program involving the sterile insect technique (SIT) for the control of mosquitoes, the Insect Pest Control Laboratory of the Food and Agriculture Organization-International Atomic Energy Agency (FAO-IAEA Joint Division...

Coetzeemyia, a new subgenus of Aedes Meigen (in the broad traditional sense, pre-Reinert 2000), is characterized and diagnosed. Aedes fryeri (Theobald) is removed from the subgenus Levua Stone and Bohart (genus Levua of Reinert et al. 2004) and placed in the new monotypic subgenus Coetzeemyia as its type species by present designation. Recognition of Coetzeemyia is based in part on a cladistic ...

CONCLUSIONS It is concluded that this study helps in conducting rapid survey to identify the presence of Aedes larvae with a minimum number of staff for both inspection and treatment of Aedes larvae during the epidemic situation. OBJECTIVES To predict dwellings for the presence of Aedes larvae rapidly based on Premises Condition Index (PCI) factors, we studied the possible presence of Aedes s...

BACKGROUND Aedes aegypti, the principal vector of dengue fever, have been genetically engineered for use in a sterile insect control programme. To improve our understanding of the dispersal ecology of mosquitoes and to inform appropriate release strategies of 'genetically sterile' male Aedes aegypti detailed knowledge of the dispersal ability of the released insects is needed. METHODOLOGY/PRI...

The study of demographic processes involved in species diversification and evolution ultimately provides explanations for the complex distribution of biodiversity on earth, indicates regions important for the maintenance and generation of biodiversity, and identifies biological units important for conservation or medical consequence. African and forest biota have both received relatively little...

Aedes juppi was readily infected by inoculation with virus but failed to transmit either horizontally or vertically. Seventy-five to 90% of the other 4 mosquito species became infected after ingesting 6.8-9.8 log10CPD50/ml of virus. These species all transmitted virus at the following rates on the post-infection days indicated: Aedes unidentatus (58%--day 11), Aedes dentatus (32%--day 11, 50%--...

1. St. Louis virus has been successfully transmitted in the laboratory by the following 9 species of mosquitoes from 3 genera: Culex tarsalis, Culex pipiens, Culex coronator, Aedes lateralis, Aedes taeniorhynchus, Aedes vexans, Aedes nigromaculis, Theobaldia incidens, and Theobaldia inornata. 2. Though transmission has not been demonstrated, survival of the virus for more than a few days was sh...

The total and dry body weight treated larvae of Aedes aegypti was significantly decreased at different time intervals under investigation (6, 12, 24, and 48 hrs) post-treatment with LC30 of Bt subsp. Kurstaki HD-1. The body water content was decreased significantly at 6 hrs post-treatment, while it was highly significant at the three other treatments. Also hemolymph volume was significantly dec...

The species composition and seasonal population dynamics of mosquitoes trapped in the Belek Region of Turkey are described. Eight traps (four New Jersey light traps and four CO2 baited traps) were activated weekly at four different sampling sites (wooded area, open field, village, and road edge). Between May and December, 1997, 4,542 specimens representing seven species (Culex pipiens, Culex tr...

Blood meal analysis of Aedes aegypti and Aedes albopictus, collected from cattle sheds and human dwellings in the highly congested residential areas of the city, and from outdoor situations in an urban garden, revealed a high bovine blood index of both the species in the former and a high human blood index in the latter two collection areas. The difference in the various blood indices of each o...
