Sticky board sampling of leafhoppers in 3 apple orchards under different management regimes

摘要

Sticky boards were placed inside and outside 3 apple orchards under different management regimes to sample the typhlocybine leafhoppers:Typhlocybafroggatti, T. lethierryi, Ribautiana tenerrima, Zygina zealandica, Z. dumbletoni, andEuteryx melissae. Adults of the mymarid parasite, Anagrus armatus, were also sampled. The number and position of capture of adult leafhoppers were related to the position of their known host plants within or close to the orchard. Leafhopper populations were low in orchards sprayed with insecticides to control other apple pests. In contrast, the unsprayed orchards had high leafhopper numbers. Strategies for the control of the apple pestT. froggattiare discussed.
