متن کاملInsect 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 کاملOptimal control problem on insect pest populations
In this article we present a model of insect infestation of grape vines and consider the optimal control of the pest through the use of egg pesticides. We show existence and uniqueness and present the results of some numerical simulations.
متن کاملCompanion Planting and Insect Pest Control
There is growing public concern about pesticides’ non-target effects on humans and other organisms, and many pests have evolved resistance to some of the most commonly-used pesticides. Together, these factors have led to increasing interest in non-chemical, ecologicallysound ways to manage pests [1]. One pest-management alternative is the diversification of agricultural fields by establishing “...
متن کاملPest Evaluation in Sustainable Cabbage Production Systems
Conservation tillage systems provide optimum conditions to reduce soil erosion and increase surface soil organic matter. This experiment was established with the longterm goal of developing conservation tillage systems that use either chemical inputs to produce vegetables and control pests, or legume cover crops, biological pesticides, and tillage to provide plant nutrition and control pests. T...
