Aphid, cabbage

Cornell University researcher Glenn Herrick found that the female cabbage aphid produces an average of 41 offspring and that the aphid produces 16 generations from April to October. If all the descendants of one female aphid lived, there would be 1,560,000,000,000,000,000,000, 000 aphids by the end of the summer. ...

We have recently reported the first purification of an insect myrosinase and its partial characterization from the cabbage aphid (Brevicoryne brassicae).9 Of all aphids examined for myrosinase,10 only the crucifer specialists, B. brassicae and Lipaphis erysimi, possessed activity although some other polyphagous aphids such as Myzus persicae can also feed on crucifers.

By the beginning of the 1990s, houseflies, Colorado potato beetles, cockroaches, peach aphids, cabbage moths and several other insect species became insensitive to all the insecticides used. 

Because some form of brassica crop can be growing at any time of year, cabbage whitefly and mealy aphids can build up in considerable numbers. It pays to remove all members of this crop family once a year—in early spring, for example—to break the cycle. 

Many Insects have become specialists on crucifers and a few related plant families. These Include flea beetles, leaf beetles, cabbage root fly, aphids, cabbage butterflies and the dlamondback moth. At the same time, several polyphagous Insects such as the cabbage looper, armyworms and aphids are major pests of crucifers. Comparative studies on these specialists and generalists have provided valuable Information on host recognition and possible resistance mechanisms. 

Methamidophos is an insecticide and acaricide for control of chewing and sucking insects and spider mites such as aphids, flea beetles, whiteflies, cabbage loopers, thrips, cutworms, Colorado potato beetles, armyworms, mites, leafhoppers, and others on vegetables, cotton, potatoes, and fruits. It has an oral LD50 in rats of 250-500 mg/kg. 

Ryania is made from the ground roots of the tropical shrub Ryania speciosa. The active principle of ryania is the alkaloid ryanodine (C25H35NOu). Ryania is used for controlling aphids, cabbage loopers, Colorado potato beetles, diamondback moths, cucumber beetles, leafhoppers, corn earworms, European corn borers, codling moths, citrus thrips, and so on. Its oral LD30 in rats is 1200 mg/kg so it is practically nontoxic to mammals. 

Beneficial Effect Valuable for controlling aphids, springtails, mites, nematodes, flies, and cabbage maggots. Also help decompose organic matter. 

Bright yellow pans or basins full of water with a few drops of liquid soap added are attractive to winged aphids and cabbage root flies. Adding soap breaks the surface tension of the water, so insects sink to the bottom. The yellow color attracts the pests, who try to alight and are drowned. 

Protection Offered Water traps are useful for monitoring winged aphids and cabbage root flies in the home garden.
