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 کاملPotato aphid, Macrosiphum euphorbiae (Thomas), in tomatoes: plant canopy distribution and binomial sampling on processing tomatoes in California.
A binomial sampling method for the potato aphid, Macrosiphum euphorbiae (Thomas), on processing tomato plants, Lycopersicon esculentum (Mill), is proposed. Relationships between mean number of M. euphorbiae per leaf and proportion of leaves infested [P(I)] with M. euphorbiae for both upper and interior leaves of the processing tomato varieties 'Alta' and 'Halley' are presented. A split-plot des...
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 کاملThe future of insect growth regulators in vector control.
Insect growth regulators (IGRs) are diverse groups of chemical compounds that are highly active against larvae of mosquitoes and other insects. The IGRs in general have a good margin of safety to most nontarget biota including invertebrates, fish, birds, and other wildlife. They are also relatively safe to man and domestic animals. The IGR compounds do not induce quick mortality in the preimagi...
متن کاملPopulation Dynamics of the Colorado Potato Beetle in an Agroecosystem with Tomatoes and Potatoes with Management Implications to Processing Tomatoes
We evaluated the population dynamics of Colorado potato beetle in processing tomatoes and potatoes using immigration proÞles, density through time, rates of development and survivorship. We also evaluated the beetleÕs inßuence on yield of processing cultivars. Colorado potato beetle immigrated into both crops. The Þrst available crop had the earliest immigration event and higher immigrating adu...
