of some feed inside tissues including pods and fruits. -inducing species manipulate plant metabolism to create distinct gall with differential biochemical profiles.

Human Relevance

T. cajaninae has reached pest status on pigeon pea at agricultural research facilities in India, with potential for broader agricultural impact. Control measures are complicated by use that reduces natural without controlling the pest.
