Abstract

Fuller’s rose weevil, Naupactus cervinus check for this species in other resources (= Asynonychus check for this species in other resources = Pantomorus cervinus) (Boheman), is a cosmopolitan pest that currently represents a serious quarantine problem for the Chilean citrus industry due to its similarity at the egg stage with the quarantine pest Naupactus xanthographus check for this species in other resources (Germar). The objective of this research was to study the biological aspects associated with N. cervinus and N. xanthographus oviposition habits under laboratory conditions on orange ( Citrus sinensis check for this species in other resources [L.] Osbeck) fruit. Adult N. cervinus and N. xanthographus were collected from the field to carry out the research. Results show that N. cervinus fecundity was higher than N. xanthographus by more than 70%, but egg viability was lower. It was recorded that 71.90% N. cervinus ovipositions were under the calyx. Likewise, 52.46% N. xanthographus ovipositions occurred on leaves and 40.98% on the surface of the plastic cage. In the present study, only N. cervinus lays egg masses under the calyx of citrus fruit.
