黑肩绿盲蝽在寄主植物、飞虱和叶蝉卵上的生长和发育

 系统地测定了不同寄主卵和寄主植物对稻飞虱重要天敌黑肩绿盲蝽Cyrtorhinus lividipennis Reuter生长和发育的影响。结果表明，在实验室条件下黑肩绿盲蝽能在水稻以及禾本科杂草如稗草Echinochloa glabrescens、千金子Leptochloa chinensis、马唐Digitaria ciliaris和狗牙根Cynodon dactylon上生长和繁殖。大田连续采样证实该盲蝽在稻田周围杂草地只能作短暂停留。黑肩绿盲蝽的若虫龄数随寄主卵和寄主植物的变化而变化，表现为5龄、6龄和4龄。水稻和禾本科花穗与飞虱蜜露或蜂蜜的结合可为黑肩绿盲蝽的生长和发育提供重要的营养源。该研究将为黑肩绿盲蝽的自然保护利用提供重要的理论依据。

Effects of Various Non-rice Hosts on the Growth, Reproduction and Predation of Mirid Bug, Cyrtorhinus lividipennis Reuter

The effects of various host plants and eggs on the predatory mind bug, Cyrtorhinus lividipennis Reuter were studied. The results in laboratory conditions showed that this mind bug could survive and reproduce on gramineous plants such as Echinochloa glabrescens, Asptochloa chinensis, Digitaria ciliaris and Cynodon dactylon. However, the weekly field sampling revealed that Cyrtorhinus lividipennis could temporarily settle on the gramineous vegetation surrounding rice fields. The instar number of this mind bug was affected by its host eggs and plants, 5, 6 or 4 instars were recorded on various hosts. The plant flower (containing nectar and pollen) with honeydew or honey solution would supply the necessary nutrients for the development and growth of Cyrtorhinus lividipennis.
