10 Plants That Keep Bugs Away In Gardens & Field

Pest infestation in the garden or field is major problem food producers face during the process of cultivation. Several insect pests are affecting the healthy growth of plants. One of these is the bugs or leaf bugs.

Bugs are insect pests usually small in size and small-bodied. They can be identified with their bright color and four-segmented antennae and beak. Bugs damage a plant by sucking the sap juice at any stage or age of the plant. Sucking of sap juice by bugs reduces the plant vigor, and ultimately makes the plant wilt. The females lay eggs on the pocket of a plant stem, these eggs hatch during the spring and regenerate causing more damage to the plant community.

Important Bugs and Damages Caused

There are about 10,000 species of bugs. They are location and plant-specific. the yellowish four-lined plant bug, Poecilocapsus lineatus, feeds mainly on blueberries, currants, and gooseberries.

Another important bug is the tarnished plant bug (Lygus pratensis), the bug is dark in color and highly voracious as it feeds on many plant species, ranging from trees to grasses and cereals. The tarnished plant bug is a common pest in North America.

Another leaf bug that causes damage to the apple tree is the apple red bug (Lygus mendax). This apple orchard pest sucks the juice from apple plant sap and causes spots on the apple tree leaves reducing the photosynthesis and the quality of the fruit produced.

The bugs that cause damage to vegetable plants are the garden fleahopper (Halticus bractatus). The bugs are black in flower and can jump from one spot to another. The garden fleahopper sucks the sap of vegetables and make the vegetable wilt.
