Many insect bacterial pathogens are not toxic enough for field control. Combinations of bacteria may increase toxicity. Bacteria toxic to Colorado potato beetle , Photorhabdus luminescens, Chromobacterium violaceum and Serratia marcescens , were tested in pair-wise combinations in an in vitro double streak test to determine bacterial compatibility. Only C. violaceum and S. marcescens grew to confluency. Their combined toxicity in vivo was additive. Other bacterial combinations had clear zones between bacterial streaks indicating inhibition. In the insect, the combined toxicity was less than the most toxic bacteria of the pair. For these strains, this in vitro test predicted compatibility in the insect. |
