What are Aphids (Aphidoidea)?
Aphids are true bugs that vary in size from 1 to 10 mm having a different color that depends on the type of climate where they grow & reproduce. Generally, they are pale-green & black while commonly found aphid in a home garden is green. They possess two whip-like antennae at the tip of the head opposing a pair of cornicles. Female aphid’s hatching takes place at the beginning of spring that produces more female nymphs. Aphids may have 7 generations in a cooler climate that may go up to 20 in hot tropical areas. This rapid multiplication creates a big menace for the gardeners to rip them fully. They overwinter as eggs on plant debris and stubbles and become active in the next spring.
These tiny creatures live on the tender shoots and flowers of the plants and suck sap leaving honeydew which becomes excellent growing media for fungi growth causing different sort of mildews and wilts on the Cannabis plants. Stunted plant growth leads to death of the plants eventually these pests move to other shoots and leaves of the neighboring healthy plants.
Aphid’s infestation is more common on weak plant or plants having stunted growth, deficient in Phosphorus & Potash fertilizers. Aphid infestation is more frequent when the days are hot and the nights are relatively cooler. Aphids pierce their stylus to suck the sap of the plants looking greener due to excessive nitrogen application. Aphids feed on the plant Phloem, rich in minerals and sugars, responsible to carry these nutrients to other parts of the plant. The result is the more Honeydew and more chances of fungal & bacterial disease attack on the Cannabis, vegetables, fruit trees and roses.
