The use of long lasting insecticide nets (LLINs) treated with pyrethroïd is known for its major contribution in malaria control. However, LLINs are suspected to induce behavioral changes in malaria vectors, which may in turn drastically affect their efficacy against Plasmodium sp. transmission. In sub Saharan Africa, where malaria imposes the heaviest burden, the main malaria vectors are widely...

In herbivorous insects, food selection depends on sensitivity to specific chemical stimuli from host-plants as well as to secondary metabolites (bitter) and to sugars (phagostimulatory). Bitter compounds are noxious, unpalatable or both and evoke an aversive feeding response. Instead, sugars and sugar alcohols play a critical role in determining and enhancing the palatability of foods. We assum...

Lycorma delicatula (Hemiptera: Fulgoridae), the spotted lanternfly, native to China, invaded and established in northeast U.S. 2014. Since this time, populations have grown spread rapidly, invasion bridgeheads been detected mid-western states (i.e., Indiana 2021). This invasive pest presents a significant threat Californian agriculture. Therefore, proactive classical biological control program ...

Emerald ash borer (EAB), Agrilus planipennis is a buprestid species native to Asia, where it pest of trees, Fraxinus spp. Since was accidentally introduced the United States in 1990s, this beetle has become one most destructive invasive pests North American trees. In 2015 found attacking white fringe tree, Chionanthus virginicus, indicating potential for host range expansion. This study evaluat...

Spotted-wing drosophila ( Drosophila suzukii ; SWD) is an invasive pest in the United States that responsible for significant economic damage to soft-skinned fruit and berries worldwide. SWD uses a wide variety of cultivated wild reproduction. Host suitability may depend on physical chemical factors fruit, with positive correlation oviposition larval development generally associated soluble sug...

The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), is an important insect pest of cruciferous crops. Understanding its preference patterns can lead to more efficient management methods, such as trap Several strains P. were used test whether there differences in oviposition a four-choice setting, on abaxial versus adaxial leaf surfaces 28 different plant species, and substr...

While the role of host preference in ecological speciation has been investigated extensively in terrestrial systems, very little is known in marine environments. Host preference combined with mate choice on the preferred host can lead to population subdivision and adaptation leading to host shifts. We use a phylogenetic approach based on two mitochondrial genetic markers to disentangle the taxo...

This paper presents research findings on the contemporary practices and socio-cultural traditions of transhumant agro-pastoralism (TAP) in Bhutan. Despite the widespread practice of TAP in Bhutan, there has been limited research on the nature of the practice and associated socio-cultural traditions. Qualitative research methods were used to interview 24 migrating households and nine relevant ag...
