摘　　要：为探明光周期对叉角厉蝽生长发育及繁殖的影响.在温度(26±1)℃,相对湿度(70±7)%的条件下,测定了7组光周期分别为24L∶0D,16L∶8D,14L∶10D,12L∶12D,10L∶14D,8L∶16D,0L∶24D条件下叉角厉蝽的生长发育和繁殖情况.结果表明,光周期对叉角厉蝽生长发育和繁殖有显著的影响.随着光照时间的增加,叉角厉蝽若虫发育历期和产卵前期缩短,若虫存活率、雌雄成虫寿命、产卵次数、产卵量和孵化率先增加后降低.当光周期为0L∶24D时若虫发育历期(19.02 d)和产卵前期最短(8.35 d);16L∶8D条件下雌雄成虫寿命寿命最长,分别为50.81 d和47.47 d,产卵次数最多(15.76次),产卵量(663.1粒)和孵化率最高(85.77%).综上所述,光周期为16L∶8D时最适合叉角厉蝽生长发育和繁殖.To clarify the effects of photoperiod on Eocanthecona furcellata(Wolff.),the develop-ment of nymph and fecundity of adults were investigated in the laboratory under temperature(26±1)℃,relative humidity(70±7)%and different photoperiods(24L∶0D,16L∶8D,14L∶10D,12L∶12D,10L∶14D,8L∶16D and 0L∶24D).The results show that the photoperiod had a significant effect on the development and reproduction of E.furcellata.The nymph s development periods and pre-oviposition periods shortened,with increasing photoperiod,whereas survival rate,longevity of female and male adults,oviposition times,reproduction and hatching rates first increased then decreased.The shortest Nymph s development periods and pre-oviposition periods was at the photoperiod of 0L∶24D,were 19.02 d and 8.35 d respectively.The longest longevity of female and male adults,oviposition times,reproduction and hatching rates was at the photoperiod of 16L∶8D,were 50.81 d,47.47 d,15.76,663.1 and 85.77%respectively Generally the photoperiod of 16L∶8D was the most suitable condition for E.furcellata,development and reproduction.
