Laboratory and field experiments were conducted to study the effect of UV filtration on the population growth, distribution and flight activity of the green peach aphid Myzus persicae (Sulzer) (Homoptera: Aphididae), and on the fecundity and host-finding behavior of the parasitic wasp Aphidius matricariae (Haliday) (Hymenoptera: Braconidae). The work was done in the Arava Valley of Israel, in walk-in tunnels covered with polyethylene film, to compare the effects of UV-absorbing film versus those of regular film. Following artificial aphid infestation on pepper grown under the tested films, aphid population growth and spread under the UV-absorbing films were significantly less than under the regular films. The greatest impact of UV-absorbing film on aphid behavior was observed in winter and early spring, when temperature conditions favor aphid development. Elimination of UV by UV-absorbing film did not affect the parasitic activity of A. matricariae. Previous results had indicated that covering the greenhouse with UV-absorbing films inhibited the invasion of aphids and other insect pests into it. That effect, in combination with those described in the present paper, makes the use of UV-absorbing films an effective component of IPM that aims to reduce the application of toxic insecticides.
