盲椿象是棉花上的主要害虫之一,我县有绿盲椿象和中黑盲椿象两种。绿盲椿象是优势种,发生早,为害大,损失重。及早做好绿盲椿的预测预报,抓好防治工作,对保护棉花安全现蕾、早结桃关系很大。过去盲椿象的测报,多以调查若虫、成虫数量为主,对发生期很少作出正确的预测,往往贻误防治,难以控制为害。为了摸索绿盲椿象发生期的预测方法,我们进行了卵和各龄若虫历期的观察,并试以作出发生期的预报。
Blind stinkbugs are one of the major pests on cotton. There are two kinds of green blind stinkbugs and black blind stinkbugs in our county. Green blind stinkbug is the dominant species, occurred early, harmful to the large, heavy loss. Good early forecast of green blind Chun, do a good job in prevention and control work, to protect the safety of cotton bud, early peach great relationship. In the past, the measurement of blind stinkbugs was mostly based on surveys of nymphs and adult worms, and rarely correctly predicted the occurrences. They often delained the prevention and control and were hard to control. In order to explore the prediction method for the occurrence of green-blind Stinkbug, we conducted observations on the duration of eggs and nymphs at various ages and tried to make predictions on the occurrence of the stage.
