通过绿豆象自由选择和无选择大豆种子两组试验,研究了绿豆象产卵量、羽化数量及羽化率等生物学特性与大豆种子含水量的关系。在自由选择试验中,大豆含水量从6.5%上升到12.5%,绿豆象在大豆上的产卵量从85.00粒增加到352.75粒,羽化成虫数从14.75头增加到230.00头,羽化率从17.34%上升到65.15%;在无选择试验中,大豆含水量从6.5%到12.5%,绿豆象在大豆上的产卵量从117.50粒增加到到310.00粒,羽化成虫数从19.50头增加到198.00头,羽化率从16.78%上升到63.83%。试验数据显示随着大豆种子含水量的增加,绿豆象产卵量、成虫羽化的数量以及羽化率都在增加,绿豆象更喜欢在含水量大的大豆种子上产卵。
Two experiments were conducted to study the relationship between the biological characteristics such as fecundity, eclosion number and eclosion rate and the water content of soybean seeds. In the free choice experiment, the water content of soybean increased from 6.5% to 12.5%, the number of oviposition of mung bean on soybean increased from 85.00 to 352.75, the number of eclosion increased from 14.75 to 230.00, and the emergence rate increased from 17.34% To 65.15%. In the no-choice test, the moisture content of soybean increased from 6.5% to 12.5%, the number of eggs laid in soybean increased from 117.50 to 310.00, the number of eclosion increased from 19.50 to 198.00, Emergence rate rose from 16.78% to 63.83%. The experimental data show that as the water content of soybean seedings increases, the number of mung bean fecundity, the emergence of adult pests and the emergence rate are increasing. Mung bean elephant prefers spawning on the watery soybean seeds.
