Egg-laying occurs at the start of the summer once the adult beetles have had enough time to feed on plant material. However, make sure to reapply after rain to ensure its proper functioning. Previous research has shown that defoliating the crop during the winter has a negligible impact on yield, as long as it occurs before stem extension. An adult . Quite a bit of research has been done in search of reliable organic controls for crucifer flea beetles. As larvae are protected within the petioles and stems, insecticidal control can be variable - even where they are not resistant - so growers can struggle to minimise their impact on yield. Some of the chemicals that can effectively eradicate these insects include Lambda cyhalothrin, Carbaryl, Permethrin, Malathion, and Cyfluthrin. Striped flea beetles make up about 10% of the population. Heavy feeding on young plants may reduce yields or even kill plants in severe cases. 1/16 inch long), bronze-black with yellowish legs and antennae. brown or grey lines.
