Earwig in Apricot
Symptoms
Mature trees usually tolerate damage well; if the tips of young trees are damaged, growth may be stunted; shallow, irregularly shaped areas may be found on the fruit surface where the insect feeds; insects are brown and shiny with a pincer-like structure at the end of the abdomen; they can reach 1.3 cm in length.
Agent
Insect
Conditions for Disease Development
Earwigs are nocturnal and usually produce two generations per year.
Control Methods
Remove all weeds from tree bases; clean all pruning debris and loose bark around trees; wrapping trunks tightly with plastic wrap before nymphs emerge can prevent them from climbing the tree; if using insecticide, apply early in the spring when earwigs begin to be active.
Apricot Leafroller
Symptoms
Plant leaves rolled and tied together with silk webbing; feeding damage to rolled leaves; defoliation of the plant; silk webbing may also be present on fruits and there may be significant scarring on fruits due to feeding damage; larvae wriggle violently when disturbed and may drop from the plant on a silken thread.
Agent
Insect
Conditions for Disease Development
Only one generation of insects per year.
Control Methods
Monitor plants regularly for signs of infestation; remove weeds from plant bases as they can act as hosts for leafrollers; avoid planting peppers in areas where sugar beets or alfalfa are grown nearby.
Apricot Green Fruitworm
Symptoms
Large chewed holes in leaves and fruits; pale green caterpillars with a white stripe down the middle of the back on leaves and fruits.
Agent
Insect
Conditions for Disease Development
The insect usually overwinters as an adult moth and has only one generation per year.
Control Methods
If larvae damage trees, Bacillus thuringiensis sprays effectively control young larvae and can be applied during the flowering period; other organically acceptable control methods include Entrust application; if the infestation is localized or applied shortly before or during petal fall, appropriate insecticides can be used as spot treatments.
