Spodoptera exiguathe beet Spodoptera exigua moth has a wingspan of 25 to 32 mm.Its forewings are mottled gray or brown with a pale spot near the center of each wing.Its hind wings are white with dark veins and have a fringe-like border.Most chemicals cleared for home garden use will not control this pest adequately.XenTari is a biological compound based on spores of the bacteria Bacillus thuringiensis var.aizawai (Bt). XenTari works against several species of butterfly and moth caterpillars that cancause serious damage to crops.Scutello 2x is a biological compound based on spores of the bacteria Bacillus thuringiensisvar kurstaki (Bt).

leaf miner

Leaf miners are larvae of various insects: small black flies, moths, sawflies or beetles, many of them specific to certain plants.The fly that lays the eggs on beets does not lay eggs on any other plant.http://yardener.com/YardenersPlantProblemSolver/DealingWithPestInsects/PestInsectsOnFlowers/LeafminerMealy bug

Its body is covered with white waxy threads, which often make a chemical pest control little successful. A female can lay 300 to 500 eggs in a cotton-like pouch made of wax threads.http://www.biobest.be/v1/en/plagen/wolluis.htmweevils

Adult vine weevils are 8-12 mm long, have a grooved, dull black shell with patches of tiny yellow bristles. As they are well camouflaged and only active at night, they are seldom seen.
