Tetrapar 250


Shipping calculated at checkout.

Scientific name: Tamarixia triozae
Common name: Parasitoid wasp

Best used: preventively for the control of Bactericera cockerelli (Tomato Psyllid). Use a high dose release in significant infestations. In case of outbreaks of infestation, release a bottle directly in the hot spots and evenly over the entire surface of the crop.

Works by: Tetrapar parasitizes the tomato psyllid, immobilizes it and hardens the inside, developing a reddish-brown leathery mummy. This happens a week after being parasitized. The adult insect emerges roughly 2 weeks after introduction, through a round hole in the anterior end (thorax) of the mummy.  The Female wasp will also host feed.

Pack size: 100ml bottle - 250 parasitoid wasps, no carrier. 

Targeted pests: 
The Tomato Psyllid
