摘要：Cotton crop (Gossypium hirsutumL.) is considered economy crop worldwide especially in Pakistan. Cotton plays strong role in proportion of GDP and foreign exchange earnings. In Pakistan, around 55% cotton is exporting fiber commodity and 15 % area of cultivation is devoted to cotton crop especiallyBtcotton. However,Btcotton suppress the chewing pests but give a favorable niche to sucking pests. Among sucking pests, theOxycarenus hyalinipennisCosta is emerging sucking pest inBtcotton, and damaging the more than 40 different plants. Study regarding preference of seed and two-sex life table traits ofO. hyalinipennisis necessary for its eco-friendly management. Therefore, this explain the preference of cotton seeds e.g., CIM-620 (non-Btvariety), CIM-717 (non-Btvariety),Bt-CIM-632 andBt-Cyto-179 byO. hyalinipennis, as well as its fitness on these seeds under laboratory condition. Results indicated that both males and females preferredBt-Cyto-179 for ovipositing as compared to other three varieties. The developmental time from eggs to males (176.85 ± 7.43) and females (184.94 ± 7.85) were significantly longer on other verities as compared toBt-Cyto-179. TheO. hyalinipennisfemales produce significantly more eggs onBt-Cyto-179 (215 ± 2.34 eggs female-1) than those on other three seeds e.g., CIM-620, CIM 717, andBt-CIM-632. In conclusion,Bt-Cyto-179was the more suitable varieties to attract and rearO. hyalinipennisthan CIM 632, and CIM 717 seeds. And our study suggests thatBt-Cyto-179 can be used as a bait crop to controlO. hyalinipennisand rearing purpose for molecular studies.
