Apple weevil

Adult: 4.5 to 5.0 mm long.
Body: black-brown coat, yellowy body.
Host plant: apple.
Mean fecundity: 25 eggs in 4 to 5 weeks.
Egg: time until hatching, 4 to 12 days.
Larva: developmental duration, 3 weeks.



Since the larva feeds on the plant's reproductive parts, does not open and takes on a "clove-like" appearance (capped blossom). If bud-bursting is slow (cold spring), the apple weevil can lay alits eggs in buds at the prefered stage. In this case, the damage is much more serious. In years when apple bossom is abundantputs out abundant flowers, the damage done is limited and the weevil even acts as natural, and beneficial, "thinner" (apple blossom is abundant once every two years). A close watch should be kept on apple trees close to woods or abandoned orchards.
