摘要: 在同一湿度(53%RH)不同温度(14℃、17℃、20℃、23℃、26℃、29℃、32℃、35℃及同一温度(26℃)不同湿度(30%RH、53%RH、75.5%RH、85%RH、92.5%RH、100%RH)组合条件下,测定了温湿度对番茄刺皮瘿螨Aculops lycopersici (Massee)生长发育及繁殖的影响。结果表明,温、湿度对该螨存活率有明显影响,以23℃(53%RH)和75.5%RH(26℃)条件下最高,分别为89.9%和87.1%; 其发育历期较短,在14~35℃和30%~100%RH范围内,历期随温度升高而缩短,随湿度升高而延长; 番茄刺皮瘿螨的发育起点温度较高,卵、若螨和整个世代的发育起点温度分别为10.51、9.02和9.15℃。完成一代需要105.56日·度。温湿度对番茄刺皮瘿螨的繁殖力有明显影响,产卵期随温度升高而缩短,随湿度升高而延长; 产卵量在26℃(53%RH)和53%RH(26℃)下最高,每头雌虫产卵分别为44.3粒和42.2粒; 26℃(53%RH)和53%RH(26℃)条件下种群的内禀增长率最高,分别为0.2645和0.2669。结果表明,适宜的温湿度条件为温度26~29℃、相对湿度53%~75%。

Abstract:

The effect of constant temperature and relative humidity on the development and reproduction of the tomato russet mite (TRM), Aculops lycopersici (Massee) was investigated. The results showed that the survival rate of TRM were highly effected by rearing temperature and relative humidity, the highest was 89.9% at 23℃ (53%RH) and 87.1% at 75.5%RH (26℃). The developmental duration of TRM decreased as rearing temperature increased from 14℃ to 35℃, and increased as relative humidity increased from 30% to 100%. The developmental zero of egg nymph and from egg to adult of TRM were 10.51℃, 9.02℃, and 9.15℃, respectively. A total of 105.56 degree-days above a developmental zero of 9.15℃ were required to complete development from egg to adult emergence. The obvious effect of temperature and humidity on the reproductive rate of TRM was observed. It was found that the duration of oviposition decreased with increasing temperature and increased with increasing humidity. Fecundity was highest at 26℃ (53%RH) and 53%RH (26℃) with 44.3 eggs and 42.2 eggs laid per female, respectively. The highest intrinsic rate of natural increase was observed at 26℃ (53%RH) and 53%RH (26℃) as 0.2645 and 0.2669, respectively. The results showed that the optimal temperature interval for its development should be within 26-29℃ and the optimal humidity interval be within 53%-75%RH.
