Cucumber beetle (Acalymma vittatum) are severe bugs of smooth-skinned. Adults feed upon squash family plants, beans, corn, peas, and blooms of numerous yard plants. The beetles abound on seedlings, feeding upon leaves and young shoots, commonly eliminating plants, they likewise assault stems and flowers of older plants and consume holes in fruit. They fly easily and move into cultivated locations from alfalfa and other crops, and from uncultivated lands. Cucumber beetles like wetness and dislike heat, subsequently, melon fields are particularly appealing in heat throughout and after an irrigation.

The larvae eats the roots of the host plants. Typically, the beetles leave their hibernating sites early in the season, and eat seedlings right as they are arising, commonly eliminating them. They hold another risk too, the can bring bacterial disease and viruses from plant to plant, such as bacterial wilt and mosaic virus.
Ways to Identify Cucumber Beetles
Cucumber beetles are about 0.36 inch (9 mm) long and either have a greenish yellow background with black areas or rotating yellow and black stripes. Adults have to do with 1/4 inch long and have a black and yellow striped abdominal area and a dark colored head and antennae. They consume weed pollen for 2 weeks, then relocate to crop plants, laying eggs in soil at base of plants.
Eggs hatch in 10 days, larvae burrow into soil, feed upon roots for 2 to 6 weeks, pupate in mid- to late summertime. Search for holes and wilting and yellowing leaves. Crop yield will certainly be low; and plants will certainly produce yellow and stunted fruits. The larvae are worm-like, white, dark-haeded, a have 3 pairs of legs on the thorax. Grownups arise in 2 weeks to eat blooms and developing fruit. One to two generations annually.
Ways to Control Cucumber Beetles
- Growers can prevent the most substantial damage by merely postponing the planting of summer season cucurbits by a couple of weeks.
- When plants are seedlings, inspect recently grown cucurbit plants for the presence of this beetle, be watchful.
- Using straw, hay, plastic, or material as mulch can hinder cucumber beetles from laying eggs in the ground near the plants.
- Floating row covers can be a huge aid by leaving out cucumber beetles throughout the seedling phase of life.
- Cover seedlings with row covers, though you rmust eliminate throughout progressing time numerous hours every day to enable pollination.
