Background. Anopheles arabiensis is increasingly dominating malaria transmission in Africa. The exophagy in mosquitoes threatens the effectiveness of indoor vector control strategies. This study aimed to evaluate the effectiveness of fungus against An. arabiensis when applied on cattle and their environments. Methods. Experiments were conducted under semi-field and small-scale field conditio...

Evolving levels of resistance in insects to the bioinsecticide Bacillus thuringiensis (Bt) can be dramatically reduced through the genetic engineering of chloroplasts in plants. When transgenic tobacco leaves expressing Cry2Aa2 protoxin in chloroplasts were fed to susceptible, Cry1A-resistant (20,000- to 40,000-fold) and Cry2Aa2-resistant (330- to 393-fold) tobacco budworm Heliothis virescens, ...

The introduction of an agricultural pest species into a new environment is a potential threat to agroecosystems of the invaded area. The phytosanitary concern is even greater if the introduced pest's phenotype expresses traits that will impair the management of that species. The invasive tomato borer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is one such species and the characterizati...

Spinosad (Dow AgroSciences) is a mixture of tetracyclic-macrolide compounds produced by a soil actinomycete and has been classified as a bioinsecticide. Spinosad is highly active against Lepidoptera but is reported to be practically nontoxic to insect natural enemies. We assessed the impact of Spinosad in a granular maize-flour formulation on a selection of insect predators over periods of 2–14...

Green mustard (Brassica juncea L.) is a popular vegetable among the people. leaves are commonly used as complementary ingredients such chicken noodle, meatballs, etc. These vegetables easily accessible to traditional markets, supermarket, and mall. The main obstacle in cultivating green Plutella xylostella attack. P. pests can attack both vegetative generative, striking at shoots of plants from...

Insecticides are a type of pesticide that is commonly used by farmers to eradicate insect pests, one which the stink bug. Excessive use results in resistance and contamination soil, water, air. Another alternative bioinsecticides safe do not cause resistance. In this study, samples were gadung bintaro root extracts. The method maceration, after maceration process, filtrate will be tested on tar...

Introduction . Pesticide poisoning is one of the main causes mass death bee colonies observed in different countries world. However, at present, abandoning use plant protection products not possible, since insects and crop weeds are responsible for loss least half world's food supply. An increase insect pest activity due to global warming will lead even greater losses. All this dictates need a ...
