Pests in Gardens and Landscapes
Lycaenid pod borers
Lycaenid pod borer larvae are grublike caterpillars. Adults are tiny butterflies.
Lycaenid pod borers hollow and eat seeds. Holes in pods are common.
Handpick or snip caterpillars with shears.
Natural enemies normally keep populations under control. Trichogramma
parasites and Hyposoter exiguae may
attack caterpillar eggs and larvae. There are also several general
predators to keep populations under control. Bacillus
thuringiensis and spinosad are effective against
smaller larvae. Discing or rototilling after harvest can
help reduce populations.
