系统调查表明 ,荔枝蝽雌虫从 3月中旬开始产卵 ,4月上旬至 6月上旬是其产卵高峰期 ,接着进入产卵衰退期。有 86%的荔枝蝽卵是在产卵高峰期产下的。通过标记荔枝蝽卵块 ,在综合防治荔枝园中采集到两种荔枝蝽卵寄生蜂 :荔蝽卵平腹小蜂Anastatusjaponicus和荔蝽卵跳小蜂Ooencyrtusphongi ,它们的寄生率分别为 3.2 % - 18.4 %和 3.2 % - 30 .4 %。在荔枝蝽产卵中期和后期 ,这两种卵寄生蜂的联合寄生 ,使得 30 .6% - 4 7%的荔枝蝽卵死亡。在化学防治荔枝园中只采集到荔蝽卵平腹小蜂 ,而其寄生率也仅达到0 .2 % - 2 .8%。
Systematic investigations showed that the female Lyethopoda spawns from mid-March, and the spawning peak from early April to early June, then enters the oviposition decay period. 86% of the litchi stinkbug eggs are laid at peak spawning times. Two Lycopersiconidae parasitic wasps (Anastatus japonicus and Ooencyrtus phongi) were collected from the litchi orchard of Lycium barbarum by the method of labeling litchi stool eggs. Their parasitism rates were 3.2% -18.4% And 3.2% - 30.4%. In the mid and late stages of litchi stool oviposition, the co-parasitization of the two egg parasitoids caused 30.6% -47% of the litchi stool eggs to die. In the chemical control litchi garden, only Lepidoptera eggs were collected, and its parasitism rate was only 0.2% -2.8%.
