| 为明确成虫期的饲养密度、性比及补充营养对孟氏隐唇瓢虫Cryptolaemus montrouzieri Mulsant生殖力的影响, 在温度(27±1)℃、光周期L∥D=8 h∥16 h, 以柑橘臀纹粉蚧Planococcus citri (Risso)为猎物观察了不同瓢虫密度(1♂+2♀、2♂+4♀、3♂+6♀、4♂+8♀、5♂+10♀/1 000 mL)、性比(♂∶♀=1∶1、1∶2、1∶3、1∶4、1∶5)、补充营养物质(柑橘臀纹粉蚧、丰年虾卵、蔗糖水、清水)的产卵情况。结果表明, 随着成虫密度的增加, 孟氏隐唇瓢虫单雌产卵量呈下降趋势, 当成虫密度为(1♂+2♀)/1 000 mL时, 单雌产卵量最高为514.5粒, 密度为(5♂+10♀)/1 000 mL时, 单雌产卵量最低, 为331.3粒; 性比(♂∶♀)为1∶1时的单雌产卵量最高, 性比为1∶5时的单雌产卵量最低; 成虫期替代食物为柑橘臀纹粉蚧时产卵量最高, 其次为20%蔗糖水。综上, 在成虫密度较低、雌雄性比1∶1条件下, 孟氏隐唇瓢虫雌虫的生殖力更强, 成虫期在食物不足的情况下, 可用20%蔗糖水作为暂时补充, 这些结果为孟氏隐唇瓢虫的商品化生产及田间应用提供了理论依据及指导。 |

| To elucidate the impacts of adult rearing density, sex ratio, and supplementary nutrition on the fecundity of Cryptolaemus montrouzieri Mulsant, egg-laying was observed under controlled conditions (27±1)℃, L∥D=8 h∥16 h with Planococcus citri (Risso) as prey. Different adult densities (1♂+2♀、2♂+4♀、3♂+6♀、4♂+8♀、5♂+10♀ per 1 000 mL), sex ratios (♂∶♀ = 1∶1, 1∶2, 1∶3, 1∶4, 1∶5), and supplementary diets (P.citri, brine shrimp eggs, sucrose water, water) were tested. Results showed that single-female fecundity decreased with increasing adult density. At a density of 1♂+2♀ per 1 000 mL, the highest mean egg number per female was 514.5, whereas at 5♂+10♀ per 1 000 mL it was the lowest (331.3 eggs). The highest fecundity occurred at a sex ratio of 1∶1, while the lowest was at 1∶5. Among supplementary diets, P.citri yielded the greatest oviposition, followed by 20% sucrose solution. In conclusion, under low adult density and a 1∶1 sex ratio, females of C.montrouzieri exhibited stronger reproductive capacity. When food is limited during the adult stage, 20% sucrose solution can serve as a temporary nutritional supplement. These results provide theoretical and practical guidance for the commercial mass production and field application of C.montrouzieri. |
