Disclosed herein are pesticicial combinations, including combinations of Yersinia entomophaga (and/or toxin(s) therefrom) and/or Yersinia nurmii (and/or toxin(s) therefrom) with an insect virus (and/or component therefrom). As shown herein, such combinations may provide unexpected pesticidal effects and may be useful for treating insects and other pests and for enhancing plant growth and/or yield.

A nucleopolyhedrovirus (NPV), a composition comprising the NPV, and a method comprising the use of the NPV is provided. The NPV was isolated from Cryptophlebia peltastica and has insecticidal activity against several species of moths within the tortricid tribe, Grapholitini. The NPV or composition may be suitable for use in controlling insect populations, particularly populations of insects that infest plants.
