Control of Sweetpotato Whitefly Adults with Foliar Neonicotinoid Insecticides in Spring Cantaloupes, 2014

Honeydew Production by Sweetpotato Whitefly Adults and Nymphs

We determined honeydew production by male and female sweetpotato whiteflies and the effects of temperature on honeydew production of each sex. We also determined honeydew production by each nymphal instar. Overall, adult SPW produced more honeydew than nymphs. Adult females produced more honeydew than males. The relative differences between honeydew production for males and females and between ...

Neonicotinoid insecticides and bees

Risks of neonicotinoid insecticides to honeybees

The European honeybee, Apis mellifera, is an important pollinator of agricultural crops. Since 2006, when unexpectedly high colony losses were first reported, articles have proliferated in the popular press suggesting a range of possible causes and raising alarm over the general decline of bees. Suggested causes include pesticides, genetically modified crops, habitat fragmentation, and introduc...

The Neonicotinoid Insecticides—insect Management with Seed Treatments in Corn

Corn producers battle a variety of soil dwelling insect pests. Seedcorn maggots, wireworms, white grubs and several species of cutworms can attack either the seed or seedling plants and reduce the plant stand. Corn rootworm larvae feed on corn roots during midsummer and can significantly reduce the uptake of moisture and nutrients. Extensive feeding by corn rootworm larvae can reduce the roots ...

Genome sequencing of the sweetpotato whitefly Bemisia tabaci MED/Q

The sweetpotato whitefly Bemisia tabaci is a highly destructive agricultural and ornamental crop pest. It damages host plants through both phloem feeding and vectoring plant pathogens. Introductions of B. tabaci are difficult to quarantine and eradicate because of its high reproductive rates, broad host plant range, and insecticide resistance. A total of 791 Gb of raw DNA sequence from whole ge...
