摘要
以茄二十八星为试材,采用5点调查的方法,研究了江汉平原地区茄二十八星瓢虫不同虫态在马铃薯、茄子、黄瓜、辣椒、番茄以及龙葵等不同寄主植物上的发生时间及发生数量。结果表明:茄二十八星瓢虫在江汉平原发生时间是从4月初至10月底,最早在发生马铃薯上,最晚发生在龙葵上。在龙葵和茄子上发生数量较大,其次是马铃薯和番茄,在其它寄主植物上只有成虫发生。
Taking Henosepilachna vigintioctopunctata as material, the population dynamic of Henosepilachna vigintioctopunctata were studied on hosts of Solanum rnelongena Linn, Lycopersicon esculenturn Mill. , Capsicum annuurn, Solanum tuberosum, Cucumis sativus Linn, Solanurn nigrum with five-point sampling method in Jianghan plain. The results showed that H. vigintioctopunctata occurred from early April on Solanum tuberosurn to later October on Solanum nigrurn. The density of H. vigintioctopunctata was the highest on Solanurn nigrum and Solanum melongena , then on Lycopersicon esculentum and Solanum tuberosum. Only adults were found on Cucumis sativus and Capsicum annuum
