| 内容記述 | Qualitative changes in larval population which is due to population density and various environmental factors in the habitat may influence remarkably upon charac-teristics of larva, pupa and adult. Analytical studies on such problems are much important for the full-understanding of population dynamics. In the gregarious insects, especially, size of larval group may influence upon survival and other ecological and physiological characters of larva, pupa and adult. In order to make clear the qualitative change of population with size of larval group, the authors examined the effect of larval group on the characters of cocoon, i. e. , weight and size of cocoon and adult fecundity using the pine sawfly, Neodiprion sertifer in 5 areas, where the population density was quite different. The results obtained are summarized as follows: 1) Weight and size of cocoon and adult fecundity were significantly different in each area. 2) Among 5 areas, negative correlation was found in 2 areas between size of larval group and adult fecundity. However, there couldn't be recognized any relation in other 3 areas for the lack of sample. On the other hand, there was no significant relation between size of larval group and weight and size of cocoon. 3) Positive correlation could be found between weight of cocoon and adult fecundity. And further, the coefficient of regression line among them negatively correlated with the average value of weight of cocoon. The fact that variation of the weight of cocoon became smaller could make adult fecundity to be steady in the next generation of Neodiprion sertifer. | |||||
