Natural Control of Borer Pests – Moth, Beetle & Wasp Larvae
Insects called borers can be found worldwide across several unrelated groups of insects and reflects their boring larval stage that affects buds, shoots, bark, trunks of trees, shrubs and other plants. Many will develop into beetles (Coleoptera), moths (Lepidoptera), or wasps (Hymenoptera). Some borers are incredibly target specific. The larval stage damages plants by destroying internal plant tissue as they feed and mature, which can be noticed by dark or discolored areas with sap and sawdust-like residue clinging to the bark or littering the ground around trees in the case of tree borers, or by visible trails marking the leaves in the case of leafminers.
- Timing of life stages throughout the year will differ depending on the species of borer, your location and environmental conditions, but all borers go through complete metamorphosis with four life stages: egg, larva, pupa and adult.
- Eggs – Laid when adults are mating on or near the host plant. Common egg-laying sites are on or under bark, in leaf litter/detritus on the ground, and in cracks of tree trunks or branches.
- Larvae – Once hatched they bore into the host plant using digestive enzymes and begin feeding. Feeding will increase progressively as they grow.
- Pupae – Some borers pupate in or on the host plant; others drop to the soil and pupate there. No damage is done during this stage.
Adults – Emerging from the pupae, adults mate and seek out optimal sites for eggs to be laid.
