DEVELOPMENT OF FRANKLINIELLA OCCIDENTALIS (WESTERN FLOWER THRIPS)ON SUSCEPTIBLE AND RESISTANT COTTON GENOTYPES

摘要

Reproduction and development of western flower thrips were evaluated on cotton genotypes. Asiatic cotton (Gossypiumarboreum L.), accession A2-154 and upland cotton (Gossypium hirsutum L.), cultivar Deltapine 458 BGRR were used asresistant and susceptible genotypes, respectively. No thrips pre-adult developmental differences were found between the twocotton genotypes. Adult longevity of thrips reared on Deltapine 458 BGRR was significantly greater than those reared onA2-154 with 18.64 and 15.14 days, respectively. Also, the average number of thrips larvae produced per day wassignificantly greater on Deltapine 458 BGRR.
