Insect Management in Floriculture: How Important Is Sanitation in Avoiding Insect Problems?

Insect evolution: How did insect wings originate?

Recent developmental studies aimed at elucidating the evolutionary origin of insect wings highlight the difficulties of identifying homology between dramatically different structures.

Avoiding DEET through Insect Gustatory Receptors

DEET is the most widely used insect repellent worldwide. In Drosophila olfactory receptor neurons (ORNs), DEET is detected through a mechanism employing the olfactory receptor, OR83b. However, it is controversial as to whether ORNs respond directly to DEET or whether DEET blocks the response to attractive odors. Here, we showed that DEET suppressed feeding behavior in Drosophila, and this effec...

Isolation and morphological study of ecologically-important insect “Hermetia illucens” collected from Roorkee compost plant

Certain species of Hermetia illucens, also known as the Black Soldier Fly(BSF), were found in a compost plant in Roorkee located in Northern India. Its larvae arevoracious eaters of organic waste, hence can play an ecologically-important role in solidwaste management. Morphological analysis of various stages of BSF life cycle by SEMshowed that its body along with its wings is densely covered wi...

Crucifer insect pest problems: trends, issues and management strategies

Crucifer vegetables are important cultivated crops and are widely grown in many parts of the world, including the highlands in most tropical countries. They are frequently attacked by a number of important insect pests. Some have been a problem for a long time while others have become important only recently. For many, trends are apparent pertaining to their changing status, including other asp...
