Abstract Rachel Carson’s Silent Spring (1962) dramatically focused public policy on the adverse effects of the indiscriminate and excessive use of inorganic and synthetic organic insecticides. The main concern was that these insecticides lacked selective activity - they were general biocides and, thus, toxic to most animal life.

Insect Control with Insect Growth Regulators, 1988
Insecticide and Acaricide Tests, 1989Abstract Timing and rates of several insect growth regulators were evaluated for control of major apple pests and for their effect on phytophagous and phytoseiid mites. Sprays were applied by handgun operating at 200 psi to 2f-yr-old ‘Newtown’ trees. Treatments consisted of 4 single-tree replicates in a randomized block.

Methoprene is an insecticide or insect growth regulator (IGR) possessing the ability to halt the life cycle of target insects. The compound mimics the effects of the insect’s juvenile hormone, hence it may also be termed a juvenoid. IGRs do not eliminate the insect in the manner of conventional insecticides (Chapter 6). The mode of action is to prevent

Biologists in the early part of the 20th century believed that since the secondary sexual characteristics of insects were unaffected by castration, insects did not secrete hormones. This view was challenged by the conclusive experiments of Stephan Kopec in 1917, who showed by surgical maneuver, that insect metamorphosis was under the hormonal control ...

Insect Growth Regulators (IGRs)
1998In recent years many of the conventional methods of insect control by broadspectrum synthetic chemicals have come under assault and scrutiny because of their undesirable effects on human health and the environment. As a consequence, new approaches have been tested and implemented.
