Classification of cabbage aphids
What are aphids classified?
aphid, (family Aphididae), also called plant louse, greenfly, or ant cow, any of a group of sap-sucking, soft-bodied insects (order Homoptera) that are about the size of a pinhead, most species of which have a pair of tubelike projections (cornicles) on the abdomen.
What are the characteristics of aphids?
All aphids have very small eyes, sucking mouthparts in the form of a relatively long, segmented rostrum, and fairly long antennae. These insects are so small (a few millimeters in length), that winds can transport them for fairly long distances. They are often green, but might be red or brown, as well.
What does a cabbage aphid look like?
Description of the Pest
Cabbage aphids are greenish-gray with a white, waxy coating. They commonly occur in dense colonies. Adults can be winged or wingless; the winged adults have a black thorax. Adult females give birth to nymphs throughout the year in much of California.
How do you control aphids in cabbage?
Cabbage aphids are persistent and outlive many of their natural predators. You can easily make an insecticidal soap in your kitchen. Combine a few teaspoons of mild, liquid Dawn dish soap with one quart of water and mix well. Either spray or wipe the soapy water mixture on your plants and let dry.
What is the scientific name of aphid?
How do you identify aphids?
The best way to identify aphids is to check for two tail pipes (cornicles) found at the end of the abdomen. All aphids have cornicles, but some are smaller and less obvious. Aphids shed their exoskeletons (skins) as they grow. These white cast skins can be found on leaves or stuck in honeydew secretions of the aphid.
What causes aphids on a cabbage?
Weeds which belong to the cabbage family must be removed as they attract aphids as well. Seed beds should be kept clean at all times. A minimum three year rotation is advised to prevent aphid infestation. Aphids have a large number of natural enemies or predators.
How do aphids affect cabbage?
Cabbage aphids prefer to feed on young leaves, flower buds, or seed stalks in the upper part of the plant and also feed in developing Brussels sprout buds. Feeding injury includes wrinkled and downward-curling leaves, yellow leaves, and reduced growth.
What insecticide kills aphids?
Many other insecticides are available to control aphids in the home garden and landscape, including foliar-applied formulations of malathion, permethrin, and acephate (nonfood crops only).
What are aphids on plants?
Aphids are small, soft-bodied, pear-shaped insects that cluster densely on tender new growth and the undersides of leaves to suck plant juices. Plants often can withstand some aphid feeding with no adverse effect, but badly infested plants develop distorted growth and leaves may turn yellow or drop off.
What is the purpose of aphids?
Aphids are the base of many food chains in the garden, playing an important role like that of small rodents in grassland ecosystems. Many different predators eat aphids, and in turn, other insects, birds, and mammals prey on them.
What causes aphids on plants?
On healthy plants, these common insects don’t cause much harm, and beneficial insects, including ladybugs, help reduce their numbers. Aphids become more of a problem when things get out of whack, which can happen when plants are stressed by drought, poor soil conditions, or overcrowding.
What is the habitat of aphids?
What kind of habitat do they need? Aphids are almost always found on or near their food plants. If they can they sometimes hide in the curls of leaves. Anywhere there are plants there are aphids.
What is the life cycle of aphids?
Life cycle: Simple metamorphosis; parthenogenic. Most aphids reproduce sexually and develop through gradual metamorphosis (overwintering diapause egg, nymphs and winged or wingless adults) but also through a process called ‘parthenogenesis’ in which the production of offspring occurs without mating.
What damage is caused by aphids?
Aphids attack nearly all species of plants. When leaves are attacked by aphids, damage often appears first as spotty yellow discolorations, usually on the undersides of leaves; the leaves may later dry out and wilt. Some aphid species form galls or cause distorted, curled, or deformed leaves.
