四纹豆象单头雌虫的产卵量通常取决于它们唯一可以利用的豇豆量。巴西品系的雌虫和也门品系的雌虫在40粒豇豆上比在5粒或10粒豇豆上所产的卵多。但是,当给它们提供100粒或140粒豇豆时,其产卵量也不会再增加。在给尼日利亚品系的雌虫提供5粒或更多的豇豆时,其产卵量并无明显的不同。单头雌虫在不同数量的豇豆上所产的卵孵化而成的成虫数因豇豆的数量与雌虫所属的品系而变化。也门品系大约平均每粒豇豆产生一头成虫,其每粒豇豆上至少着一粒卵。因此,每头雌虫产生的后代成虫数便随着着卵的豇豆数目稳定增长。当尼日利亚品系的每头雌虫可以利用来产卵的豇豆是40粒,而不是50粒或10粒时,它就会产生更多的成虫。但是,如果它们有更多的可以利用的豇豆,成虫的数量也不会再增加。巴西品系每头雌虫产生最大数量的成虫后代所需的豇豆量为100粒。由此,可以得出结论,即决定最大限度产卵力和成虫后代产生的条件在品系内及品系间是不同的。如果把这些材料用于种群模拟,其意义就特别重要了!其原因在于它说明了这一害虫对生态因素的种内差异。
The number of fecundity in a quadruped female usually depends on the amount of cowpea they can use. The female of the Brazilian strain and the female of the Yemeni line produced more eggs on 40 cowpeas than on 5 or 10 cowpeas. However, when they are given 100 or 140 cowpeas, their fecundity does not increase any more. There was no significant difference in egg production when five or more cowpeas were supplied to female Nigerian lines. The number of adults hatched by single-headed females on eggs grown on different numbers of cowpeas varies with the number of cowpeas and the strain to which the females belong. The Yemeni line produces an average of about one adult worm per cowpea, with at least one egg per cowpea. As a result, the number of offspring that each females produce increases steadily with the number of eggs in the egg. When the Nigerian strain of cowpea that every female can use to lay eggs is 40 instead of 50 or 10, it produces more adults. However, if they have more available cowpeas, the number of adults will not increase. The amount of cowpea needed to produce the largest number of adult offspring per female in the Brazilian line is 100 grains. From this it can be concluded that the conditions that determine the maximum oviposition and the generation of adult progeny are different within the line and between lines. The reason why these materials are used for population simulation is particularly important because it explains the intraspecific differences in ecological aspects of this pest.
