Beneficial nematodes instead of attacking adults, beneficial nematodes to go after the larvae in the soil and are a safe and natural method of control. Entomopathogenic nematodes, Steinernema and Heterorhabditis spp., Have been particularly effective especially in potted plants. Some things are essential to achieve good control:
Calendar and Temperature – beneficial nematodes require a soil temperature of at least 60 F to work. Gardeners often miss the critical period in the spring as the larvae of the weevil pupate early enough, before the soil warms. Late summer and early fall is the best time to apply nematodes.
Humidity – The area of the around the plant roots should be moist, because the nematodes do not swim and need to carry water up through the floor. Water from the area before and after application.
Whitefly-There are two types of this little white fly in a triangular shape, one to make greenhouse plants and the other affecting brassicas. Both feed Sap on the underside of the leaves causing stiffness and yellow mottling.
Control of greenhouse whitefly, can be controlled with yellow sticky traps and Encarsia parasitic wasps, whiteflies, while the cabbage can be addressed by blasting them with jets of water from a hose.
Winter Moth-moth caterpillars mottled ocher (ankeraria defoliaria), winter moth (Winter Moth) and March Moth (Alsophila aescularia) have wingless females, who after leaving her in the chrysalis stage ground, must climb the tree to mate and lay their eggs.
Control – are sticky grease bands coated paper that can be cut to length, wrapped around the trunks of fruit trees in September – up from December and March. Alternatively apply grease fruit trees, the paint on the lower trunk fruit trees and any tree supports. Grease traps of wingless females before reaching branches. Winter moth is the most common of these moths and emerges as an adult in mid-November through January.
Apply grease to the fruit trees like apple, pear, plum and cherry. In trees without protection eggs hatch in the bud and pale green or yellowish brown looper caterpillars feed rate of the leaves, flowers and fruits allows.
Note: the bands fat does not protect against codling moth (Cydia pomonella) and other pests that can fly above the trees.
The wire-worm (Agriotes lineatus), This creature, which grows to about 25 mm long, spends four years living in the soil. During the summer pupa, this stage lasts three weeks to emerge as Click adult beetles. They feed on roots, particularly potatoes and other tubers, making tunnels about 3 mm in diameter. They are usually widespread in grasslands are often well when placed in culture. It is believed that after five years of growing their numbers decrease significantly.
Control: – 1 Lift main crop potatoes – before September, since most of the damage is done now.
2 crush any that are found by digging.
3 I heard that a trap made of squares attached to skewers potatoes, buried in the ground is a good way to catch them, they can be uprooted and destroyed infested potatoes. I must admit I have not used this method, but I could try.
4 Keep the weeds, since this is the kind of territory that the beetle likes lay their eggs.
