【摘要】 本文对河南科技学院校园红花酢浆草访花昆虫进行初步调查,定点观察了不同访花昆虫的访花行为、访花频率、日活动规律及在小花上的停留时间。结果发现红花酢浆草访花昆虫共计5目14科18种,中华蜜蜂、意大利蜜蜂、长脚胡蜂、黑带食蚜蝇和菜粉蝶为主要的访花昆虫。意大利蜜蜂的访花频率较高为0.43次/秒花,黑带食蚜蝇在小花上的停留时间最长40.8s,意大利蜜蜂和中华蜜蜂访花频率的日变化规律为双峰型。红花醉浆草的访花昆虫在晴天的10:00—14:00这个时间段较多,下午15:00之后部分小花开始闭合,个体数迅速下降,且不同昆虫的日变化规律有显著差异。更多还原

【Abstract】 This paper carried out preliminary investigation on visiting insects of Oxalis corymbosa on Henan Institute of Science and Technology campus,and observed pointing the different flower-visiting insects foraging behaviors、visiting frequency、daily activity patterns and residence time on the florets.The results showed:Red sorrel flower-visiting insects totaling 5 orders,14 families and 18 species,of which the Apis cerana,Apis mellifera,Polistes olivaceus、Episyrphus balteatus and Pieris rapae as the main flower-visiting insects.Apis mellifera visit flowers higher frequency of 0.43,Episyrphus balteatus flies flowers stay on the longest 40.8 s,Variation of Apis mellifera and the Apis cerana visiting frequency of the day is bimodal.Oxalis corymbosa sorrel of pollinators at 10:00 a 14:00 this time period are more sunny,Oxalis corymbosa pollinators grass on a sunny day at 10:00 a 14:00 this time more,but part of the flowers begin after 15:00 pm close,the rapid decline in the number of individuals,and the diurnal variation was significantly different insects differences.更多还原
