近年来海南岛种植的腰果遭受茶角盲蝽Helopetlis fasciaticollis Poppius及安妥角盲蝽H. antonii Signoret严重危害。两种角盲蝽的成、若虫均危害腰果嫩梢、花枝、未成熟的果及果梨。据1982年调查,果被害率达100%,其中被害至干枯的达7%。茶角盲蝽广布于海南岛,除危害腰果外,尚危害可可、茶树、胡椒、红毛榴裢、洋蒲桃、番石榴等多种作物;此虫年发生12代,一代需时16~80天。安妥角盲蝽仅分布于海南岛陵水,只危害腰果,一代需时20~51天。根据两种角盲蝽的危害及生物学特性,对其防治可采取选用合理种植规格,除去带卵枝条及梢期、花期、座果期喷射农药等措施。
In recent years, the cashew nuts planted in Hainan Island suffered serious damage from Helopetlis fasciaticollis Poppius and H. antonii Signoret. Two kinds of horn bugs into, nymphs are endangering the young shoots, flowering branches, immature fruit and fruit pears. According to the 1982 survey, the rate of damage was 100%, of which 7% was harmed to death. Lygus is widely distributed in Hainan Island, in addition to endangering the cashew nuts, but also endanger the cocoa, tea, pepper, red pomegranate, plum, guava and other crops; this pest occurred in 12 generations, a generation takes 16 ~ 80 days. Lycaenidae is only distributed in Lingshui, Hainan Island, only endangering cashew nuts, a generation takes 20 to 51 days. According to the damage and biological characteristics of two kinds of Apodemus agalactiae, the measures of reasonable planting can be adopted for their prevention and control, and the measures of spraying pesticides such as shoots with shoots, flowering stage and fruit stage are removed.
