Insect Growth Regulators with Juvenile Hormone Activity
Annual Review of Entomology, 1975The term insect growth regulator (IGR) was designed to describe a new class of bio-rational compounds. Through greater selectivity of action these compounds appear to fit the requirements for third generation pesticides, such as the absence of undesirable effects on man, wildlife, and the environment and compatibility with modern insect pest management

Modeling insect growth regulators for pest management
Journal of Mathematical BiologyInsect growth regulators (IGRs) have been developed as effective control measures against harmful insect pests to disrupt their normal development. This study is to propose a mathematical model to evaluate the cost-effectiveness of IGRs for pest management.

The use of insect growth regulators for the control of insect pests of cotton
International Journal of Pest Management, 1999Studies were conducted to evaluate the effectiveness of insect growth regulators for the control of cotton insect pests. Three field trials were carried out and the insect growth regulators including lufenuron (A 7814) and lufenuron plus profenofos (A 9441) were compared with lambda-cyhalothrin.

The role of insect growth regulators in arthropod control
Parasitology Today, 1993Insect growth regulators (IGRs) represent a relatively new category of insect control agents aimed mainly at covering the need for safer compounds and overcoming the development o f resistance to 'classical' insecticides. The various types of IGR are reviewed here by Jean-Francois Graf and their mechanism of action, their practical application and ...

Salannobutyrolactone and its deacetylderivative were tested for insect antifeedant and growth regulatory activities against the tobacco cutworm, Spodoptera litura. Salannobutyrolactone was the most effective antifeedant. Desacetylsalannobutyrolactone increased larval duration and larval mortality.

Insect Growth Regulators: Resistance and The Future
1983In 1967 Carroll Williams summarized several years of campaigning for a revolution in pesticide chemistry with the publication of an article entitled “Third Generation Pesticides.” His lectures on the golden oil of Ceovopia helped to inspire the identification of the first juvenile hormone (JH) structure (Roller et al., 1976) as well as the synthesis of

The Hormonal Regulation of Growth and Reproduction in Insects
1964Publisher Summary This chapter describes the maximum number of common factors in the growth control system of insects; reviews current ideas about the nature of the action of the hormones at the cellular level; and differentiates these immediate effects from the secondary consequences of hormonal action.
