摘要
以白星花金龟为对象,研究了营养和湿度对其生殖的影响。在室内条件下,以不同饲料饲养成虫,取食桃的白星花金龟产卵量最高,为103粒/头,其次是苹果和梨,而取食西瓜皮的产卵量最低。土壤湿度对白星花金龟成虫产卵量影响很大,以西瓜皮为食饲喂成虫,土壤湿度为15%时,成虫产卵量最高为48.2粒/头,过干过湿都不利于成虫产卵。
This study makes use of Potosia brevitaris Lewis adult as the materials, studies the influence of nutrient andhumidity on its reproductive. Under laboratory condition, different food was used to breed the adult. The result show that thePotosia brevitaris Lewis adult which feed by peach has the highest fecundity, the eggs that pure female adult produces canreach 103. The Potosia brevitaris Lewis adult which feed by apple and pear is followed, and feeding watermelon skinspawning has the minimum Fecundity. Soil humidity dialogue has significantly affected on the fecundity of the Potosiabrevitaris Lewis adult. When the moisture content of the soil is 15%, the Potosia brevitaris Lewis adult which feed byWatermelon rind has the highest fecundity, the most eggs pure female adult produces can reach 48.2.It is not good for adultlaying eggs when the soil is too dry or too wet.
