在室内25℃恒温条件下,饲养观察了绿豆象[Callosobruchus chinensis(Linn.)]对不同豆种的产卵选择性、产卵量、卵的孵化率、幼虫和成虫的生长发育历期。结果表明,供试的17种豆粒上绿豆象的着卵率均达80%以上,且不同豆种粒上产卵量差异显著(P<0.01),卵在不同豆种上的孵化率间也存在显著差异(P<0.05),卵孵化后,幼虫仅在蚕豆、绿豆、红皮豇豆、豌豆、黑豆、红小豆、大豆上可蛀入危害,蛀孔数分别为3.00±0.25,2.00±0.18,3.50±0.09,2.50±0.21,4.50±0.10,2.00±0.22,2.50±0.17蛀孔/豆,差异显著(P<0.05)。在蚕豆、绿豆、红小豆、红皮豇豆、黑豆、大豆粒上的世代存活率分别为(0.63±0.12)%,(54.84±0.09)%,(44.40±0.08)%,(46.33±0.11)%,(66.88±0.10)%,(45.71±0.11)%,(21.59±0.21)%;雌虫的产卵期分别为(4.24±1.58)d,(5.10±0.22)d,(5.40±0.26)d,(5.21±1.25)d,(5.30±0.38)d,(4.63±0.41)d和(4.30±0.80)d,差异不显著(P>0.05),卵历期分别为(5.01±0.15)d,(4.30±0.05)d,(4.10±0.08)d,(5.10±0.18)d,(4.30±0.07)d,(4.20±0.14)d及(4.51±0.16)d,差异不显著(P>0.05);幼虫的平均历期分别为(33.40±4.85)d,(31.60±1.78)d,(28.22±3.56)d,(30.91±2.49)d,(27.30±1.98)d,(29.50±1.93)d及(36.70±4.97)d,差异显著(P<0.05)。不同豆种上绿豆象雄虫寿命间差异不显著(P>0.05),而雌虫寿命差异显著(P>0.05)。
The oviposition preference, fecundity, egg hatchability, larval and adult growth and development duration of Callosobruchus chinensis (Linn.) Were observed in an indoor environment of 25 ℃. The results showed that the eggs of mung bean on the 17 kinds of beans were more than 80%, and the differences in the number of eggs laid on different kinds of beans were significant (P <0.01). The hatching rate of eggs on different kinds of beans was also (P <0.05). After egg hatching, the larvae were only able to invade on Vicia faba, mung bean, red cowpea, pea, black bean, adzuki bean and soybean, the number of moth holes was 3.00 ± 0.25,2.00 ± 0.18 , 3.50 ± 0.09,2.50 ± 0.21,4.50 ± 0.10,2.00 ± 0.22,2.50 ± 0.17 moth per hole, the difference was significant (P <0.05). The survival rates of the three generations were (0.63 ± 0.12)%, (54.84 ± 0.09)%, (44.40 ± 0.08)% and (46.33 ± 0.11)% respectively in the broad bean, mung bean, adzuki bean, , (66.88 ± 0.10)%, (45.71 ± 0.11)% and (21.59 ± 0.21)%, respectively. The spawning periods of females were (4.24 ± 1.58) days, (5.10 ± 0.22) days and , (5.21 ± 1.25) d, (5.30 ± 0.38) d, (4.63 ± 0.41) d and (4.30 ± 0.80) d, respectively. The difference was not significant (P> 0.05) (4.30 ± 0.05) d, (4.10 ± 0.08) d, (5.10 ± 0.18) d, (4.30 ± 0.07) d, (4.20 ± 0.14) d and (4.51 ± 0.16) d respectively The average duration of larvae was (33.40 ± 4.85) d, (31.60 ± 1.78) d, (28.22 ± 3.56) d, (30.91 ± 2.49) d, (27.30 ± 1.98) d, (29.50 ± 1.93) d and (36.70 ± 4.97) d, the difference was significant (P <0.05). There was no significant difference in the longevity of Mung bean male on different soybean species (P> 0.05), but the difference in longevity of female was significant (P> 0.05).
