1、茶翅蝽的生物学特性 1、年生活史:在豫东地区,茶翅蝽一年发生1～2代,凡成虫在5月上中旬及其以前产的卵,到7月上中旬羽化为第一代成虫,可继续产卵,经过若虫阶段再羽化为越冬成虫,一年发生2代,6月上旬以后产的卵,只发生一代。 2、各虫态历期:成虫期:茶翅蝽越冬代平均225天,最长266天;第一代平均25天,最长31天。卵期:茶翅蝽1.5～2.5天。若虫期:茶翅蝽35.5±5.5天,且一龄最短,五龄最长。在适温区内,卵期和若虫期与温度呈负相关。 3、越冬成虫的出、入蛰期:经连续四年调查,在豫东地区,茶翅蝽最早出蛰期在4月初,出蛰盛期在4月下旬至5月上旬。总出蛰期约50天,人蛰期从9月底开始,入蛰高峰在10月中旬,到10月下旬绝大部分成虫
1, the biological characteristics of the tea leaf bugs 1, the annual life history: In the eastern part of Henan, Ocimum turkey occurs 1 to 2 generations a year, where adult adults in mid-May and the previous eggs, mid-July Emergence of the first generation of adults, can continue to lay eggs, and then emerge as wintering adult nymph stages, one generation a year, after the first half of June produced eggs, only a generation. 2, the worm state duration: adult period: tea odon overwinter on average 225 days, the longest 266 days; the first generation averaged 25 days, the longest 31 days. Egg Period: Tea wing bugs 1.5 ~ 2.5 days. Nymph period: Tea leaf bugs 35.5 ± 5.5 days, and the first age is the shortest, the longest five years. In the suitable temperature zone, egg stage and nymphal stage were negatively correlated with temperature. 3, overwintering adult out, into the sting period: After four consecutive years of investigation, in the eastern part of the region, the first sting out of the tea leaf stink bug in early April, a sting out peak in late April to early May. The total output of about 50 days sting, sting from the end of September, into the sting peak in mid-October, to the end of October the vast majority of adults
