Lp. Schaub et Nd. Stone, AN EMPIRICAL OVIPOSITION MODEL OF BOLLWORMS (LEPIDOPTERA, NOCTUIDAE) IN COTTON REPRESENTING STOCHASTICITY DUE TO MIGRATION, Agricultural systems, 45(1), 1994, pp. 1-18
A model of oviposition is developed to be used as input into a stochas
tic simulation model of bollworm population dynamics to describe ovipo
sition from immigrating females in individual fields. Three years of s
couting data from two Texas counties were used to parameterize a time-
dependent function describing the probability of finding a given numbe
r of eggs per sample of 25 plants. The negative binomial distribution
fits the oviposition observations of each year better than seven other
theoretical distributions.
