The diurnal pattern of oviposition by Toxorhynchites moctezuma (Dyar & Knab), ambient relative humidity, and ambient air temperature were monitored hourly between 0600 and 1800 hours for 46 consecutive d in a tropical rainforest in Trinidad, West Indies. The mean number of eggs per ovitrap per hour was correlated negatively with mean ambient relative humidity and positively with air temperature. Partial correlation coefficients among these variables and contingency table analysis indicated a stronger relationship between the oviposition rate and relative humidity than between oviposition rate and temperature. We suggest that this relationship is further evidence of the ability of female Tx. moctezuma to detect suitable oviposition sites using humidity gradients.
在西印度群岛特立尼达的一片热带雨林中，连续46天，每天06:00至18:00每小时监测一次莫氏巨蚊（Toxorhynchites moctezuma，戴尔和克纳布命名）的产卵昼夜模式、环境相对湿度和环境气温。每个诱蚊产卵器每小时的平均卵数与平均环境相对湿度呈负相关，与气温呈正相关。这些变量之间的偏相关系数和列联表分析表明，产卵率与相对湿度之间的关系比产卵率与温度之间的关系更强。我们认为，这种关系进一步证明了雌性莫氏巨蚊能够利用湿度梯度来探测合适的产卵地点。
