Comparative laboratory experiment with Orius insidiosus and Orius albidipennis (Het.: anthocoridae) , two candidates for biological control in glasshouses

Abstract: The predatory bugsOrius insidiosus andOrius albidipennis are potential candidates for biocontrol of the thrips,Frankliniella occidentalis. Laboratory experiments showed thatO. albidipennis lays significantly more eggs thanO. insidiosus while its life cycle is shorter. As more eggs are laid byO. albidipennis in the beginning of the oviposition cycle, this anthocorid may be considered as the better biocontrol agent.
