摘要
为探究蠋蝽低温饲养效果,延长蠋蝽货架期。本研究对低温T1(15℃)和T2(10℃)条件下,小群体饲养的初始处理龄期为3龄、4龄、5龄蠋蝽若虫及成虫的部分生长发育参数和蜕皮激素含量进行测定分析。研究结果表明:随着饲养温度降低,蠋蝽食物与水的更换(补给)频次降低,蠋蝽在T1和T2温度条件下均能发育、但若虫发育历期随温度降低显著延长,蠋蝽羽化成虫后的虫体质量随温度和初始饲养龄期的降低而降低;T2-3("-"后的数字代表蠋蝽龄期)组蠋蝽若虫不能发育至成虫,T1-3和T2-4组蠋蝽若虫可以发育至成虫、但较多成虫翅畸形,T1-3和T2-3组5龄若虫蜕皮后第5 d的蜕皮激素含量(27.37ng/L和24.21 ng/L)显著低于CK-3(30.16 ng/L);T1-4、T1-5和T2-5组蠋蝽若虫能发育至成虫,且T1-4和T1-5组蠋蝽羽化的成虫可以在该温度下交配产卵(7.04粒、10.25粒);T2组中仅有T2-5、T2-雌成虫两组蠋蝽在恢复饲养观测期内有产卵(9.24粒、17.05粒),但产卵量显著低于CK组(27.26粒),T1温度各组均在恢复饲养观测期内有产卵,且高龄期组卵量显著高于低龄期组。
The effects of low temperature on growth and development of Arma chinensis Fallou were investigated at low temperature conditions of T1(15 ℃) and T2(10 ℃) for the purpose of shelf life. The results show that frequency of food and water replacement for A. chinensis decreased with the decrease of temperature. A. chinensis could develop under low temperature conditions, but the development significantly prolonged with the decrease of temperature. Weight of A. chinensis adults decreased with the decrease of temperature and initial feeding age. The nymphs T2-3(3 after ’-’ represents the 3rd instar) were not able to develop to adults, the nymphs T1-3 and T2-4 were able to develop to adults, but most of them had deformed wings. The ecdysone contents on the 5 th day after the insects entered the 5 th instar were significantly lower in T1-3 and T2-3(27.37 ng/L and 24.21 ng/L) than in CK-3(30.16 ng/L). The nymphs T1-4, T1-5 and T2-5 were able to develop to adults, and the adults of T1-4 and T1-5 could oviposit(7.04, 10.25) at the temperature. In the T2 groups, only T2-5 and T2-female adult could oviposit(9.2, 17.05) during restored feeding, but the oviposition was significantly lower than that of the CK group(27.26). Females in the T1 groups all could oviposit during restored feeding, and the oviposition in the older instar group was significantly higher than that in the younger instar group.
