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 کاملBehavior in Insect Mimicry
Arthropods use insect mimicry to gain predatory advantages over other insects in the form of increased resource availability and protection from predators. They do this through several different mechanisms, 4 of which are described in the paper; Batesian, Peckhamian, Wasmannian, and Tephritid mimicry. ‘Mimicry’ includes resemblances in both appearance and behavior. Without mimicry in both appea...
متن کاملeffect of two insect growth regulators (igrs) on trialeurodes vaporariorum (homoptera: aleyrodidae)
the effect of four concentrations (0.5, 1, 2.5, and 5 mg/lit) of two insect growth regulators (igrs) of buprofezin and pyriproxifen on 1 and 4-day eggs, different nymphal instars, and pupae of trialeurodes vaporariorum (homoptera: aleyrodidae), was studied at 26 ± 2 °c, 80 ± 5% rh, and 16: 8 (l: d) on lantana camara in the greenhouse. the effect of both igrs was positively related to incr...
