Influence of Insect Growth Regulators on Stephanitis pyrioides (Hemiptera: Tingidae) Eggs and Nymphs

Insects, 2019
The azalea lace bug, Stephanitis pyrioides (Scott) (Hemiptera: Tingidae), is an important insect pest of azaleas (Rhododendron L. spp.) in the USA. Stephanitis pyrioides feeds on azalea foliage and causes extensive chlorosis, which reduces the aesthetic ...

Environmental and toxicological aspects of insect growth regulators. [PDF]

Environmental Health Perspectives, 1976
Insect growth regulators (IGRs) are a class of new chemicals that interfere with maturation and reproduction in insects. Proposed hypotheses on the biochemical mechanism of action are presented herein. The environmental aspects as metabolism in soils, plants, insects, and animals suggest strongly that these chemicals undergo rapid degradation and ...

growth inside the insect

, 2008
International audienceWe report global expression profiling of a uvrY-deficient mutant of Photorhabdus luminescens. We found that the regulator moiety of the two-component regulatory system BarA/UvrY regulated more than 500 target genes coding for ...

A new binding mode for ecdysteroid analog tebufenozide as a multitargeted IGR with chitinase

Advanced Agrochem
Tebufenozide, an efficient insect growth regulator (IGR) against lepidopteran pests, presents a novel mode of action with minimal non-target impact. By competing with ecdysteroids for ecdysone receptor (EcR) binding, it regulates insect growth precisely.

Control of malaria vectors with the insect growth regulator pyriproxyfen in a gem-mining area in Sri Lanka.

, 2001
The study was conducted in eight adjacent villages in central Sri Lanka where there are many shallow pits dug by gem miners that fill with water. These become breeding places of the main malarial vector Anopheles culicifacies, and of the second most ...

Various novel insecticides are less toxic to humans, more specific to key pests

California Agriculture, 2005
A number of novel insecticides have recently been registered for insect control in agriculture. A major advantage of these new products is that they act on insect biological processes that humans do not experience, such as molting. Many
