Insect Growth Regulators for Insect Pest Control*
Insecticides with growth regulating properties (IGR) may adversely affect insects by regulating or inhibiting specific biochemical pathways or processes essential for insect growth and development. Some insects exposed to such compounds may die due to abnormal regulation of hormone-mediated cell or organ development. Other insects may die either from a prolonged exposure at the developmental st...
متن کاملInsect growth regulators and insect control: a critical appraisal.
Insect growth regulators (IGRs) of the juvenile hormone type alter physiological processes essential to insect development and appear to act specifically on insects. Three natural juvenile hormones have been found in insects but not in other organisms. Future use of antagonists or inhibitors of hormone synthesis may be technically possible as an advantageous extension of pest control by IGRs. A...
متن کاملAlkylene-bis-isothiocyanates: Novel Insect Growth Regulators
In search for selective anti-insect agents some monoand bis-isothiocyanates were prepared and tested on third instar larvae of Manduca sexta. The alkylene-bis-isothiocyanates 4, 5 and 6 had a novel effect preventing formation of the abdominal spiracles and of the hooks (crochets) at the following molt to the 4th instar. Some of these larvae died in the molt, while spiracles remained absent also...
متن کاملInsect physiology: The emerging story of ecdysis
The discovery of a new insect peptide hormone that triggers ecdysis - shedding of an old cuticle - has revealed hidden layers of intricacy about an insect behavior previously thought to be mediated by a single neuropeptide.
متن کاملEvaluation of Two Insect Growth Regulators (IGRS) As a Feed- Through Treatments against Adults of Culex pipiens L. mosquito
This study was carried out to evaluate the biological effects of two IGRs (Match and Baycidal) on Culex pipiens mosquitoes when fed the adults on sugar solution mixed with 0.1, 0.5 and 1 ppm of each compound. Some delayed effects of these treatments were also determined. The results indicated that the use of each of the tested IGRs caused a reduction in the blood-feeding activity of mosquito fe...
