Biological control using egg parasitoids particularly from the genus Trichogramma and Telenomus remus is part of the IPM approach presently underway to control FAW in North and South America. The approach involves mass rearing and release of these egg parasitoids to control FAW. These egg parasitoids are reared on factitious and natural hosts. Host parasitism by different egg parasitoids (–%), obtained in the present study, was close to (–%) that recorded by previous authors who studied the percentages of parasitism by different Trichogramma spp. against different hosts (Chailleux et al. and Cabello et al. ).
Introduction. Egg parasitoids of the genus Trichogramma are employed worldwide for the biological control of insect pests (Smith, ), and are also widely used as model insects for has been demonstrated that although factitious host eggs were readily accepted by certain Trichogramma females, other wasps of the same laboratory line delayed parasitization for a period up to 10– release of Trichogramma egg parasitoids. Inundative releases of commercially produced Trichogramma one for release of each of the four Trichogramma species and a no-release control. Each Trichogramma species was released at a rate of , parasitized eggs per ha Trichogramma minutum, al-.
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. InWajnberg E. and Hassan S. A.

Trichogrammatid Trichogramma minutum book parasitoids are used worldwide as inundative biological control agents for lepidopteran pests in forestry, orchard, and row crops (LiSmith ). Trichogramma platneri Nagarkatti is an arboreal species known to attack C.
pomonella, and is indigenous to the United States west of the Rocky Mountains (Pinto et al. ).Cited by: Trichogramma is a genus of minute polyphagous wasps that are endoparasitoids of insect eggs.
Trichogramma is one of around 80 genera from the family Trichogrammatidae, with over species worldwide. Although several groups of egg parasitoids are commonly employed for biological control throughout the world, Trichogramma spp. have been the most extensively : Insecta.

Two critical factors are the environmental conditions into which parasitoids are released and the biologi- cal attributes of the parasitoids being released.

Abstract. Inundative releases of Trichogramma minutum Riley for biological control of the spruce bud‐worm, Choristoneura fumiferana (Clemens), were investigated in Canada's boreal forest during and The most significant factors affecting the level of egg mass parasitism were the time of release, the density of the parasitoids, and the local weather conditions.

Rice, (Oryza sativa L.), is liable to infestation with several insect pests, from which is the rice stem borer, Chilo agamemnon Bles. (Lepidoptera: Crambidae). Field trials were conducted in Egypt during and rice seasons to evaluate the efficacy of releasing the egg parasitoid, Trichogramma evanescens Westwood and applying different silica materials to reduce the pest.

where N a is the number of eggs parasitized by the parasitoid, N is the initial density of the host eggs, a is the instantaneous attack rate, T is the total time of host-parasitoid exposure (24 h in this study), and T h is the handling time (h).
Nonlinear least squares regression (Wilkinson ) was used to estimate the parameters a and T h in the functional response equation. Trichogramma spp.
are small wasps that are endoparasites of lepidopteran eggs. The major advantage of Trichogramma species as biological control agents is their extremely small size; adult egg-parasitoids measure only mm in length, making them virtually invisible to the casual observer (Fig.
