    Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management can be an important component of integrated pest management (IPM) programs.. There are three basic strategies for. RELEASE AT FIRST SIGHT OF MOTHS. Target Pests: Over pest moth species.

    Two species of Trichogramma wasps were assessed for their effectiveness against yellow stem borer Scirpophaga incertulas. A laboratory cage test with T. japonicum and T. chilonis showed that both species parasitized yellow stem borer egg masses at % ± % and % ± %, respectively, with egg parasitism rates of % ± % for T. japonicum and % ± % for T. chilonis. Once Cited by: 5. This tiny parasitic wasp is an effective biological control agent because it kills its host before a plant can be damaged. Despite its miniscule size — 1mm or less — Trichogramma pretiosum  is an efficient killer of some undesirable insects. It uses smell to determine the suitability of a host for deposit of its egg.

Use of the parasite Trichogramma minutum for controlling pecan insects by Herbert Spencer Download PDF EPUB FB2

Trichogramma minutum is a moth egg parasite native to the eastern parts of the United States. It is commonly used in orchards, in vineyards and on ornamentals for preventative control of various caterpillars and borers.

When timed appropriately, Trichogramma releases can significantly reduce moth/caterpillar populations and limit pesticide use/5(7). Get this from a library. Use of the parasite Trichogramma minutum for controlling pecan insects.

The biological control it is one the most important issue of Integrated Pest Management, and one the options is to use the egg parasitoid Trichogramma, which is widely used throughout the world.

Trichogramma brassicae is especially useful for controlling moth populations on cole crops. Use T. brassicae in cooler climates with low-lying plants affected by caterpillar and/or borer damage. Trichogramma help prevent and control moth larvae including tomato hornworm, cabbage looper, armyworms and more.5/5(2).

Trichogramma wasps are used for control on numerous crops and plants; these include cotton, sugarcane, vegetables, sugarbeets, orchards, and forests.

Some of the pests controlled include cotton bollworm (Helicoverpa armigera), codling moth (Cydia pomonella), lightbrown apple moth (Epiphyas postvittana), Class: Insecta.

The species most commonly found in Europe and America are respectively T. evanescens, Westw., and T. minutum, Riley. The characteristics that determine the adaptability of Trichogramma to biological control work are briefly enumerated, and the effect of farm practices on its abundance and the methods adopted by earlier Cited by: Trichogramma platneri, a western U.S.

native, is recommended for western trees. The avocado strain of T. platneri has garnered rave reviews. We also rear a codling moth strain of T. platneri for western apple, pear and walnut growers. Trichogramma minutum is best for eastern states, where it is native, overwinters, and colonizes all tiers of trees.

Because their life cycle from egg to adult is about 7 to 10 days, these parasites have many more generations than their hosts, and their populations can increase rapidly. Trichogramma turns the eggs of some caterpillar species black. This is the best way to detect parasitization by Trichogramma.

“Biological control” of pests involves either natural or human-assisted control of certain pest species by predators, parasites (parasitoids, as defined below) or pathogens.

This circular outlines important definitions, concepts and examples of biological control of some common yard and garden pests in. Trichogramma wasp larvae provide natural pest control by eating insect eggs, especially those of cabbage worms, codling moths and European corn borers.Trichogramma (T.

While this is the ideal product for moth control in orchards (or crop settings where concentrations of pest moths are high), be mindful that unless used in a controlled environment (greenhouse, large isolated orchard), you may affect the population of non-target moths and.
