Alfalfa Caterpillar Parasite
A small braconid wasp that parasitizes alfalfa butterfly caterpillars in agricultural fields. Larvae spin white cocoons after emerging from the host.
Did You Know?
It can reduce alfalfa caterpillar populations by over 50% in some fields without any pesticide use.
Sugarcane Woolly Aphid
A small aphid covered in white woolly wax secretions that forms dense colonies on the undersides of sugarcane leaves. Heavy infestations reduce cane juice quality and sugar recovery in mills.
Did You Know?
A major outbreak of this pest devastated the Indian sugarcane crop in 2002-2004 before biological control with parasitoid wasps brought it under control.
