“…In this manner a total of about 12 000 weevils produced 6 000 ml of ODP extract, which was then concentrated to 60 ml by evaporation under room temperature. The extract was checked for its biological activity (Tanaka, 1991), and served as a stock pheromone, which was held at 4 • C when not being used.…”

Artificial selection was conducted to reduce the behavioral responsiveness of female bruchid beetles, Callosobruchus chinensis, to the oviposition deterring pheromone excreted by conspecific females. Significant responses to selection were observed after two generations of selection. Realized heritability was estimated as 0.052 ± 0.017 from cumulative responses regressed on cumulative selection differentials. These results indicate that this pheromone communication system has significant additive genetic variance needed for its evolution.

“…The mechanism of avoidance of occupied hosts is unknown but probably involves a marking pheromone (Credland & Wright, 1990). A study of the closely related species, C. chinensis, indicated moderate within-individual repeatability in the avoidance of pheromone-treated seeds (Tanaka, 1991). Niamey.…”

Heritability and ‘evolvability’ of fitness components in Callosobruchus maculatus

Heritabilities of traits closely related to fitness (e.g. life-history traits) tend to be lower than those of morphological traits in natural populations. It is unclear, however, whether this pattern reflects relatively low additive-genetic variation, relatively high residual variation (i.e. non-additive and environmental effects) or both. A standard, half-sib breeding design was used to estimate narrow-sense heritabilities and coefficients of additive-genetic variation (CVA) for a life-history trait (total fecundity), a morphological trait (wing length) and a behavioural trait (allocation of eggs among available resources) in two outbred populations of the seed beetle Callosobruchus maculatus. Heritabilities of fecundity and wing length were high in both populations whereas the heritability of egg-laying behaviour was low but non-zero. In contrast, estimates of 'evolvability', which depend on Cl/A, were highest for fecundity, intermediate for egg-laying behaviour and lowest for wing length. These results resemble those from a recent survey of Drosophila studies and suggest that the typically low heritabilities of behavioural or life-history traits are better explained by high residual variation than by low additive-genetic variation. Phenotypic and genetic correlations were generally not significant except for a positive relationship between wing length and fecundity. No evidence was obtained of a trade-off or underlying functional relationship between the number of eggs laid and the pattern of egg dispersion among available resources.
