A survey of exotic beetles that attack trees or shrubs in New Zealand found 51 species of mainly Australian (58%) and European (25%) origin. In addition, three biological control agents have been released against woody adventive plant pests. The host range of most species is restricted to exotic crop and ornamental plants in New Zealand. Nine polyphagous borers sometimes attack dead wood of ind...
The predator Podisus distinctus (Stål) (Heteroptera: Pentatomidae: Asopinae) has been reared to control lepidopteran defoliators. In this study, we describe this predator's morphology, postdepositional dynamics and eggs in different developmental stages under scanning electron microscope. Its eggs are subglobular and ovoid, narrower at the base than at the top, with a convex, circular operculum...
A field trial to determine the effect of different dosages, Scheduling time plant growth regulators and defoliators on yield cotton under high density planting system was conducted at Regional Agricultural Research Station, Warangal during kharif-2022. The experiment consisted eleven treatments laid out in Randomized Block Design with three replications. treatment details were T1: Application M...
Models of outbreaks in forest-defoliating insects are typically built from a priori considerations and tested only with long time series of abundances. We instead present a model built from experimental data on the gypsy moth and its nuclear polyhedrosis virus, which has been extensively tested with epidemic data. These data have identified key details of the gypsy moth-virus interaction that a...
