Efficacy of a novel neem oil formulation (RP03 ™) to control the poultry red mite Dermanyssus gallinae
Abstract Dermanyssus gallinae (Mesostigmata: Dermanyssidae) is the most harmful ectoparasite of laying hens, represents an occupational hazard for poultry workers, and a growing threat to medical science per se. There is increasing demand for alternative products, including plant‐derived acaricides, with which to control the mite. The present study investigated the efficacy of neem oil against D. gallinae on a heavily infested commercial laying hen farm. A novel formulation of 20% neem oil, diluted from a 2400‐p.p.m. azadirachtin‐concentrated stock (RP03™), was administered by nebulization three times in 1 week....

In vitro studies of larvicidal effects of some plant extracts against Anopheles gambiae larvae (Diptera: Culicidae)
Larvicidal effects of plant extracts against larvae of Anopheles gambiae were studied in the malaria entomology laboratory at Mendefera. The aim of the study was to evaluate ethanol and hot water extracts from leaves of seven different plants, viz., Azadirachta indica, Eucalyptus globulus, Tagetes minuta, Datura stramonium, Lantana camara, Ricinus communis and Jatropha curcas, as natural lar...
