菊酯类农药对荔枝蝽象成、若虫有良好的防治效果,并已广泛地用于防治荔枝蝽象。但据我们在福州金山调查,荔枝蝽象产卵量大,卵孵化率高,每株成年荔枝树卵量多者达数万粒,少者也达上千粒。因此进一步了解菊酯类农药对荔枝蝽象卵的防效,将有利于提高菊酯类农药对荔枝蝽象的防治技术。为此,我们于1987针对当前国内外拟除虫菊酯的主要品种进行了室内、外试验观察。
Pyrethroid pesticides on litchi stinkbug, nymphs have good control effect, and has been widely used to control litchi stinkbug. However, according to our investigation in Jinshan, Fuzhou, litchi stinkbugs produce a large amount of eggs and have high egg hatching rates. Therefore, further understanding of the effectiveness of pyrethroid pesticides on litchi stinkbugs would be beneficial to the prevention and control of litchi stinkbugs. To this end, we in 1987 for the current domestic and foreign pyrethroids major indoor and outdoor experiments were observed.
