GENERAL INFORMATION Click here for an explantaion of the general chemical status information
for Bracon gelechiae

Description: A small parasitic wasp that can be used for the biological control of various moth pests

Example pests controlled: -

Example applications: -

Appearance and life cycle: Very small wasps (~ 0.1mm long) with a long slender abdomen. The adult female paralyse and deposit up to 8 eggs in individual instar moth larvae. Enzymes from the wasp gut quickly destroy the blood proteins in the moth larvae leading to its death.

Availability status: -

Introduction & key dates: 1945, introduced into USA to control potato tuber moth
