中文摘要:为明确不同光环境对梨小食心虫Grapholita molesta成虫寿命和繁殖的影响,于室内条件下测定不同光照强度(10 000、1 000、100、1和0.01 mW/m2)与不同波长光(红光630 nm、黄光575 nm、绿光510 nm、蓝光455 nm、紫光440 nm和紫外光365 nm)照射下梨小食心虫的成虫寿命、交配率、产卵前期、产卵期、单雌产卵量、卵发育历期和卵孵化率等生物学参数进行分析。结果表明,相较于10 000、1 000和100 mW/m2高光照强度处理,1 mW/m2和0.01 mW/m2低光照强度处理下,梨小食心虫雌、雄成虫寿命较短(<15 d),单雌产卵量较低,分别为51.44粒和51.02粒;卵发育历期较长,分别为3.36 d和3.24 d;产卵前期和产卵期均以1 mW/m2处理最短,分别为3.80 d和5.19 d;交配率和卵孵化率在不同光照强度下无显著差异。相较于黄光、绿光和蓝光,红光和紫外光环境下梨小食心虫雌、雄成虫寿命缩短(<13 d),交配率降低,分别为54.45%和65.56%;产卵前期延长(>5.5 d),产卵期缩短(<6 d),单雌产卵量降低,分别为38.34粒和57.60粒;卵发育历期在红光、蓝光和紫外光处理下较短,分别为2.66、2.58和2.65 d;卵孵化率在紫外光处理下最低(89.90%),显著低于其他波长光处理。表明光环境可影响梨小食心虫成虫寿命和繁殖力,其中低光照强度或红光、紫外光均能抑制其繁殖力,不利于种群发展,可用于该害虫田间光诱控技术的开发。

Abstract:In order to elucidate the effects of light environments on the adult longevity and reproduction of oriental fruit moth Grapholita molesta, the experiments on measure the adult longevity, mating rate, pre-oviposition duration, oviposition duration, fecundity, egg duration, and hatching rate under different light intensities (10 000, 1 000, 100, 1and 0.01 mW/m2) and wavelength ranges (red light, 630 nm; yellow light, 575 nm; green light, 510 nm; blue light, 455 nm; purple light, 440 nm; and ultraviolet (UV) light, 365nm) were conducted in the laboratory. The results showed that, compared to higher light intensities (10 000, 1 000 and 100 mW/m2), lower intensities (1 mW/m2and 0.01 mW/m2) led to shorter adult longevity (<15 d), reduced fecundity (51.44 and 51.02 eggs, respectively), and longer egg duration (3.36 d and 3.24 d, respectively). In addition, pre-oviposition and oviposition durations were extended under 1 mW/m2, with 3.80 d and 5.19 d, respectively. There was no significant difference in the mating rate and egg hatching rate under different light intensities. Compared to yellow, green and blue light, exposure to red and UV light resulted in shorter adult longevity (<13 d), lower mating rates (54.45% and 65.56%, respectively), longer pre-oviposition periods (>5.5 d), shorter oviposition period (<6 d), and reduced fecundity (38.34 and 57.60, respectively). Egg duration was shorter under red, blue and UV light (2.66, 2.58 and 2.65 d, respectively), and egg hatching rate was the lowest under UV light (89.90%), which significantly lower than those under other wavelength ranges. The study indicates that light environment significantly affects the adult longevity and reproduction of G. molesta. Lower light intensity, as well as exposure to red and UV light, were found to inhibit reproductive ability, which may not be conducive to population development. These results offer insights into light environment setting for indoor breeding and the development of light trapping technology in the field.
