Managing Insects and Arthropod Pest Flashcards
What are the general tactics for managing pests?
biological control host plant resistance genetic control cultural control physical and mechanical control chemical control
Most important step to pest management
scout and monitor
Id skills are vital for pest management true or false
true
Insecticide Resistance is most common in?
insects that produce several generations per year
pests exposed to several sprays each season
Herbivorous (plant eating) pests
What is cross resistances?
pests develops resistance to 2 or more compounds usually chemically related
What is multiple resistance?
pest tolerate insecticides from different classes of compounds with different modes of action
Single compounds or mixtures that have more than one mode of action provide better resistance management, why
because they attack more than one chemical in insect, synergists applied with insecticides break down resistance by interfering with pests enzymes
How does altering the patterns of insecticide help avoid insecticide resistance?
not enough of pest population is exposed therefore can’t as a population alter their genes to resist the insecticide
what are ways patterns can be altered
rotating compounds with different modes of action altering timing altering placement spot treating treating alternate generations
exotic pest
not from the environment it is currently living in
What is the tell tale sign of the corn borer
