Insecticides can affect development and survival of non-target and beneficial arthropods like honey bees (Apis mellifera L.). Thiamethoxam and spinosad are widely used as pesticides in agriculture but they have become an important concern for beekeepers and researchers focusing on bee health; multiple reports stressed adverse effects on bees, notab...
Insect pests are serious constraints to production of maize. There is little information on the control measures against those insects in Cameroon. This study was carried out to identify the different species of fall armyworm and stem borers of maize and test the efficacy of different control methods. The maize variety ATP (Acid Tolerant Population...
Agricultural practices often involve tank-mixing and co-application of insecticides with fungicides to control crop pests. However, natural methods relying on biological control agents such as hymenopteran parasitoids have been shown to be highly effective in suppressing crop pest populations. The current body of insecticide risk assessment data ac...
The life-history parameters and predation capacity of Macrolophus pygmaeus Rambur and Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) fed on eggs of Plutella xylostella (L.) (Lepidoptera: Plutellidae) at 25 degrees C were investigated in the laboratory and analyzed based on the age-stage, two-sex life table. Also, we evaluated the survival and th...
Social bees represent an important group of pollinating insects that can be exposed to potentially harmful pesticides when foraging on treated or contaminated flowering plants. To investigate if such exposure is detrimental to bees, many studies have exclusively fed individuals with pesticide-spiked food, informing us about the hazard but not neces...
Open Access Journal; Published online: 20 July 2018 / Lambda-cyhalothrin (λ-cyhalothrin) is the most commonly used pyrethroid insecticide for vegetable farming in Benin. This insecticide is misused and overused by farmers, and hence may pose health hazards to consumers. We monitored λ-cyhalothrin residues in lettuce and cabbage from farms at the ma...
The processing of yam into dehydrated chips is used extensively in certain areas of West Africa to stabilize the product. However, the chips are often severely attacked by borers, which can reduce whole stocks to powder within a few months. The level of protection provided by various biological products derived from neem (Azadirachta indica) and Cr...
Little empirical evidence on economic value of biological control of pests at farm level is available to improve economic decision-making by farmers and policy makers. Using insect sampling and household survey in an integrated bio-economic analysis framework, this paper studies farmers' crop management practices in cotton in the North China Plain,...
Open Access Journal / The management of the fall armyworm Spodoptera frugiperda in maize field necessitates the use a big quantities of insecticides and sometimes the use of multiple types and formulations of chemicals. The use of insecticides in crops is associated with environmental risks and health hazards to both producers and consumers. This s...
Open Access Journal; Published online: 20 Nov 2018 / Background Insecticide resistance in Anopheles mosquitoes is threatening the success of malaria control programmes. In order to implement suitable insecticide resistance management strategies, it is necessary to understand the underlying mechanisms involved. To achieve this, the molecular basis o...
