Abstract

Examined the influence of pinyon pine Pinus edulis stress on Neodiprion edulicolis performance. Sawflies generally performed better on trees receiving both water and fertilizer, but in some cases, sawflies did benefit from pinyon stress. Simultaneous plant stress, such as low precipitation while the insect is feeding or ovipositing, can reduce performance. Sustained plant stress, such as chronically poor soil conditions or prolonged drought, can benefit insect performance. -from Authors
