 (members of the snout beetle family, or Curculionidae), especially those that attack fruit. The term is sometimes limited to the acorn and nut weevils of the genus Curculio, characterized by extremely long beaks adapted for boring. The females, whose beaks may be twice as long as their bodies, lay their eggs in holes bored in the nuts. The larvae feed on the nuts, later pupating (see insectinsect,

) in the soil. The plum curculio, Conotrachelus nenuphar, is a serious pest of peach, plum, cherry, and apple, causing deformed and prematurely falling fruit. In spring the adults leave their winter shelter in piles of rubbish and fly to blossoming or early fruiting trees, where they feed for a week or more before mating. Eggs are laid in the fruit in slits made by the female, and the larvae feed for two to three weeks before pupating in the ground. Curculios are classified in the phylum ArthropodaArthropoda
[Gr.,=jointed feet], largest and most diverse animal phylum. The arthropods include crustaceans, insects, centipedes, millipedes, spiders, scorpions, and the extinct trilobites.

Key pests impact production of nuts, such as the pecan nut casebearer Acrobasis nuxvorella Neunzig, the hickory shuckworm Cydia caryana (Fitch), the pecan weevil Curculio caryae (Horn), and numerous species of stink bugs; secondary pests attack the foliage, such as the pecan aphids Monellia caryella (Fitch), Melanocallis caryaefoliae (Davis), and Monelliopsis pecanis Bissell, the pecan phylloxera Phylloxera sp., and the walnut caterpillar Datana integerrima Grote and Robinson (Harris, 1983; Ree and Knutson, 1997; Knutson and Ree, 2002).
The chalky barrier helps protect apples from plum curculio, codling moth, apple maggot, apple sawfly and other pests, as well as from sunburn and heat stress.
The big three that affect the apples directly are the codling moth, the apple maggot, a fly, and the plum curculio, a beetle.
Some acorns have shell damage or evidence of infestation by acorn weevils (small round exit hole; Curculio spp.) Some weevil larvae will typically emerge from collected acorns prior to the lab, and these larvae are shown to students when discussing factors that alter food perishability.
