Pests Flashcards
hormone that affects insect growth cycle
Insect growth regulator (IGR)
What is the most important thing to know if you want to control a pest?
it’s life cycle
Integrated Pest Management
process of solving pest problems while minimizing risks to people and the environment
7 elements of IPM
-Grow healthy plants
-Use resistant plants
-Keep a clean growing environment
-Remove factors that allow pests to thrive
-Biological controls
-Cultural controls
-Mechanical/physical controls
3 Biological Controls
-Predators
-Parasites
-Bacteria
2 Cultural Controls
-Irrigation practices
-fertilization
Pesticide
any substance used to kill, repel, or control a pest
Neem Oil
-safe to use on food
-leaves no residue on soil
-effectively kills pests and prevents powdery mildew
-Comes from the tree Azadirchta indica
-Non-toxic to birds, fish and bees
-Use on mites, aphids, mealybugs, scale and whitefly
bT
Bacillus thuringiensis
-a naturally occurring soil bacteria that when sprayed on plants is toxic to certain pest insects
-caterpillars, certain beetles, mosquitoes, black flies
Aphids
-Feed on new growth
-40-86 degrees, 80 degrees optimal
-Parthenogenic and sexual reproduction
-Nymphs and adults most susceptible to pesticides (eggs protected)
-Honeydew reduces photosynthesis with sooty mold
-Vectors for viruses
Controlling Aphids
-Syringe
-Isolate infested plants
-Squish
-Beneficials
-Insecticide
Signs of Aphids
-poor/distorted growth
-sticky honeydew
-sooty molds
-cast skins
-ants
-discoloration
Scale Symptoms
-Discolored stems
-Chlorosis
-Stunted plant growth
-Death of stem if infested
-Insects, waxy secretion, egg sacs
Scale treatments
-Proper cultural care
-Prune off damage
-Syringe
-Wipe off
-Insecticidal soap
White fly
-Resistance to pesticides forms quickly
-Good fliers, spread fast
-Sexual and parthenogenic
-76-86 degrees optimal
-Usually on leaf undersides
