摘 要:本研究测定了桃一点叶蝉的发育起点温度和有效积温。结果表明,桃一点叶蝉各虫态(龄)的发育起点温度分别为:卵(4.33±0.08)℃、1龄若虫(4.78±0.32)℃、2龄若虫(3.05±0.22)℃,3龄若虫(3.78±0.28)℃、4龄若虫(5.00±0.31)℃、5龄若虫(5.00±0.26)℃、成虫产卵前期(3.63±0.56)℃、全世代(8.33±0.05)℃;有效积温分别为:卵(333.33±3.75)℃、1龄若虫(108.70±3.54)℃、2龄若虫(121.95±2.93)℃、3龄若虫(121.95±2.83)℃、4龄若虫(108.70±3.83)℃、5龄若虫(166.67±3.00)℃、成虫产卵前期(40.32±4.20)℃、全世代(833.33±6.00)℃。根据福建省福安市气象资料和桃一点叶蝉的越冬习性,推算出桃一点叶蝉在福建省福安市年发生5-6代。Erythroneura sudra was a major peach post. According to the test results, the threshold temperatures were (4.33 ±0.08) ℃ for the eggs, (4.78 ±0.32 ) ℃ for the first instar nymphs, (3.05 ±0.22) ℃ for the second instar nymphs, (3.78 ±0.28) ℃ for the third instar nymphs, (5.00 ±0.31) ℃ for the fourth instar nymphs, (5.00 ±0.26) ℃ for the fifth instar nymphs, (3.63 ± 0.56) ℃ for the preoviposition period and (8.33 ±0.05) ℃ for the whole generation. The effective accumulative temperatures were (333.33 ±3.75) ℃ for the eggs, (108.70 ± 3.54) ℃ for the first instar nymphs. (121.95 ± 2.93) ℃ for the second instar nymphs, (121.95 ±2.83) ℃ for the third instar nymphs, (108.70 ±3.83) ℃ for the fourth instar nymphs, (166.67 ±3.00) ℃ for the fifth instar nymphs, (40.32 ± 4.20 ) ℃ for the preoviposltion period and ( 833.33 ± 6.00 ) ℃ for the whole generation. Based on the investigation of E. sudra annual life history and overwintering habits, it was concluded that the occurrence of E. sudra was 5 -6 generations annually in Fu'an City of Fujian Province.
