混合猎物对蠋蝽生长、繁殖和捕食能力的影响

为进一步提升蠋蝽室内繁育和田间应用技术，本研究以桑蚕蛹、柞蚕蛹为猎物，评价了单一和混合猎物饲养蠋蝽对其生长发育、繁殖和捕食能力的影响。研究发现：猎物并不影响蠋蝽若虫的发育历期，各处理下蠋蝽发育历期平均在26 d；但显著影响蠋蝽的产卵前期，混合猎物饲养的蠋蝽产卵前期为10.3 d，分别是桑蚕蛹猎物的1.54倍、柞蚕蛹猎物的1.34倍。同时，猎物显著影响蠋蝽的体型、繁殖、寿命和耐饥饿时间，混合猎物饲养的蠋蝽体型比单一猎物增加5%～9%、产卵量增加13%～38%、寿命延长2～7 d、捕食量提高15%～20%、耐饥饿时间延长20%～60%。

Effects of Mixed Prey on the Development,Reproduction and Predation of Arma chinensis

To improve the mass rearing and field application of Arma chinensis, we examined the effects of silkworm and tussah pupae used alone or in mixture on the development, reproduction and predation ability of A. chinensis. The results showed that the development duration of A. chinensis nymph did not differ between the prey treatments, which were about 26 days, but the preoviposition period of A. chinensis differed significantly. The preoviposition period of the mixed prey treatment was 10.3 days, which was 1.54 times and 1.34 times of the silkworm pupa's and the tussah pupa's, respectively. At the same time, the prey treatment significantly affected the body size, reproduction, longevity, predation, and starvation tolerance of adult A. chinensis, which increased by 5%-9%, 13%-38%, 2-7 days, 15%-20%, and 20%-60%, respectively, in the mixed prey treatment in comparison with the single prey treatment.
