BACKGROUND & OBJECTIVES Houseflies are one of the major pest problems worldwide. The current housefly control strategy in the country hinges on the use of Dichlorvos as a housefly larvicide and pyrethrum spray in kitchens/dining areas. The present study was undertaken to evaluate the newer housefly control options in the wake of concerns about human toxicity of Dichlorvos and its continued use ...

A suggestion from the Office of The Surgeon General of the United States Army to the National Research Council led, in 1942, to the development of an effective pyrethrum-containing louse powder, MYL, by a United States Department of Agriculture group working in Orlando, Fla. Field tests of this powder in artificial louse infestations during the summer of 1942 gave such promising results (Davis ...

BACKGROUND & OBJECTIVES Biting behaviour of Anopheles funestus in Mutare and Mutasa districts, Zimbabwe, is little understood. An investigation was conducted to primarily compare indoor and outdoor biting behaviour of the mosquito, as well as blood meal sources and sporozoite rates. METHODS Monthly adult anopheline sampling was conducted from October 2013 to September 2014 using Centers for D...

Dalmatian pyrethrum (Tanacetum cinerariifolium Trevir./Sch./Bip.) is an outcrossing, perennial insecticidal plant, restricted to the eastern Adriatic coast (Mediterranean). Amplified fragment-length polymorphisms (AFLP) were used to investigate the genetic diversity and structure within and among 20 natural plant populations. The highest level of gene diversity, the number of private alleles an...

We conducted a three-year entomologic study in Dielmo, a village of 250 inhabitants in a holoendemic area for malaria in Senegal. Anophelines were captured on human bait and by pyrethrum spray collections. The mosquitoes belonging to the Anopheles gambiae complex were identified using the polymerase chain reaction. Malaria vectors captured were An. funestus, An. arabiensis, and An. gambiae. Ano...

This study tested the applicability of Island Biogeographic Theory to arthropod assemblages on ‘islands’ of creosotebush (Larrea tridentata) across a desert shrubland-grassland ecotone in central New Mexico, U.S.A. We assumed that herbivorous arthropod taxa that specialize on creosotebush view these shrubs as ‘islands’ of suitable habitat in a ‘sea’ of grassland, and used the Island Biogeograph...
