Abstract:

When bands on peach trees were evaluated as artificial overwintering sites for beneficial arthropods over a 2-yr period, predaceous Hemiptera, Syrphidae, Neuroptera, Acarina, Araneida, and parasitic Hymenoptera successfully overwintered in moderate to large numbers under the bands. More than 90% of the arthropods using the bands were beneficial.

The ratio of overwintering phytophagous mites to predaceous mites was 3:1 in December 1966, but it changed by mid-February 1967 to 11:1 in favor of predaceous mites.

When the temperature and relative humidity under and around a black band was monitored, a wide range of temperature (16.7-26.7 and relative humidity (28-58%) was measured at the time of highest air temperature. When arthropod movement was restricted to a limited area of the band, high mortality occurred; when they were allowed to move around the band, the rate of survival was high for most of the species.

The spring emergence of the species of parasites, hyperparasites, and syrphids overwintering under the bands was also studied.
