桑天牛成虫生殖行为观察
Observation of reproduction behavior of Apriona germari (Hope) adults
摘要
Abstract
The author observed feeding behaviors, mating, oviposition, gnawing incision of Apriona germari adults by indoors rearing. Results showed that these adults tried to feed on 2 to 5 parts of one branch of Broussonetia papyrifera, and then chose one to continue feeding. Females ingest more food than males in a day. Adults' mating behaviors is comprised of several stages such as courtship, precopulatory mounting, mating, postcoital separate. Ovipositing incision of adults was a whole process that could be divided into four phases such as site selection,incision,ovipositing,seal. The fastigium of adults' feeding was from 6:00 to 8:00am, and the second peak appeared from 12:00 to 14:00 pm. The feeding weight of the two above-stages occupied half of whole feeding weight in one day. Male adults' courtship could last 78 - 148 s, average 119.56 s. Mating could last 312-605 s, average 445.62 s. Gnawing incision and oviposition of female could last 15 -25 min and 3 -5 min, respectively. The time of maximum oviposition was from 20:00 -22:00 pm. And the quantity of maximum oviposition could account for a third of total oviposition amount in a day. The quantity of oviposition decreased as time passing. Females' oviposition behavior could sustain for one month at least.关键词
