Abstract

In the under-structure horticulture areas of Kochi, diflubenzuron, IGR incecticide had been introduced to control the house-fly since 1985. However, in 1998 the IC-50 values of a colony of the house-flies collected in these areas (M.'98 colony: from Misato) showed more than 40,000 ppm at 10th and 20th generations colonized in our laboratory. And those of F1 F2 progenies from the straight cross between this colony (M.'98 col.) and a susceptive colony (H.'98 colony: from Harigi in 1998, the IC-50 values: 1.9-2.9 ppm at 10th and 18th generations) were reduced to 50.3-89.8 ppm. In these experiments, the inhibited rate-concentration regression line of the resistant colony (M.'98 col.), the F1 and the F2 had a distinct plateau from 156 to 40,000 ppm. And the inhibited rate of emergence at that the plateau was shown had been raised from 30-40% to 80-90% by the cross with the susceptive colony (H.'98 col.). On the other hand, the resistant colny (M.'98 col.) showed no obvious cross-resistance to cyromazine grouped in the similar insecticides to inhibit forming of epidermis with diflubenzuron.
