Dusky cotton bug Oxycarenus hyalinipennis Costa (Lygaeidae: Hemiptera) loss assessment in cotton
International Journal of Tropical Insect Science 41 (2), 1163-1167
Abstract: Oxycarenus hyalinipennis Costa (Lygaeidae: Hemiptera) has attained the status of major insect pest drastically affecting the value and production of the cotton crop. The main objective of the study is to estimate losses caused by O. hyalinipennis (10, 20, 30, 40, 50, 60 pairs release / boll) identified on boll weight, fiber characteristics (mike, staple length, staple strength, lint index and Ginning Out Turn), seed index and seed germination, under semi opened bolls of two Bt genotypes (MNH-886 and MNH-456). The offered O. hyalinipennis density is directly proportional to GOT while inversely proportional to boll weight, seed index, germination, lint index, mike, staple length and staple strength. All morphological parameters revealed highly significant but negative correlation with offered densities of O. hyalinipennis. Linear regression model showed that fiber characteristics affected significantly by O. hyalinipennis. Thus, a long term sustainable IPM strategy must be implemented to curtail this bug population under check.
