Abstract
[Objective] The aim was to examine super-cooling point and freezing point of Culcula panterinaria at different stages and clear cold tolerance of each insect state.[Method] The super-cooling points and freezing points at each development stage of C.panterinaria was measured by digital multimeter and low temperature incubator.[Result] The sequence of super-cooling point and freezing points at each development stage of C.panterinaria from high to low was the 1 st instar larvae [(-10.01 ± 0.24),(-9.75 ± 0.13) ℃],the 2nd instar larvae [(-11.24 ± 0.15),(-10.89±0.16) ℃],the 3rd instar larvae[(-12.64 ±0.23),(-12.01 ± 0.24) ℃],adult[(-14.39±0.20),(-13.76±0.22) ℃℃],the 4th instar larvae [(-14.56 ± 0.15),(-13.94 ± 0.21) ℃℃],the 5th instar larvae [(-15.36 ± 0.17),(-14.85 ± 0.18) ℃],the 6th instar larvae [(-17.87 ± 0.13),(-16.93 ± 0.17) ℃] and pupa [(-20.95 ± 0.09),(-19.78 ± 0.19) ℃℃].The super-cooling point and freezing point of C.panterinaria's female adult(-14.56 ±0.18),(-14.61 ±0.19) ℃ were lower than male adult(-14.22 ±0.22),(-12.91 ± 0.25) ℃.[Conclusion] There is significant difference of the super-cooling point and the freezing point for the C.panterinaria.And the difference of adult which were in different of super-cooling point is significant while the difference of freezing point is not.关键词
