Descriptions of several new British forms amongst the parasitic hymenopterous insects. but produced fewer progeny as indicated by life-table data suggesting that their “effective” life is shorter. Since the 1960s, improved mass production of Trichogramma and better augmentative release methods to suppress agricultural pests have been achieved. First page follows. Therefore, the identity of a species, its diverging populationsstrains/sibling speciesshould be confirmed before selecting for mass production in the laboratory, ... Trichogramma has the distinction of being the maximally produced and released natural enemy in the world ( Manjunath et al., 1988). mass liberations. few inTrichogramma is thelytoky, the later could be facultative with change in temperature, from one mode to the other.

Entomol. This is mainly because of the following attributes: short life cycle, most in tropical climate have 8-10 days from egg to egg-laying period; high breeding potential (a female can produce in its lifetime of 6-7 days of active egg-laying period between 25 and 80 females); high percentage of female progenies (60-90 %); kills the pest in the egg stage before the pest could cause any damage to the crop; amenable for mass production in the laboratories; most adapt to laboratory factitious hosts of lepidopteran insects, ... where the morphological characters are the same, but have discreet traits as observed in different spatially isolated populations of Trichogrammatoidea cojuangcoi Nagaraja in the Philippines and elsewhere (Nagaraja, 1987). A comparative study was made of the fertility, fecundity and longevity ofTrichogramma confusum and T. fasciatum P. in the laboratory and temperature experiments on them. [7] Girault A.

With the egg collection unit the scales are agitated in a closed bucket and safely collected into the dust bag of the vacuum cleaner. [24] Vuilett A. This chapter describes the protocols followed for production of host insects and trichogrammatids in India and in other countries like China and Russia. To evaluate removal of nutritional components from the E. kuehniella larval diet and reduce production costs, colonies were maintained using one of three diets: a standard diet consisting of eight ingredients, a reduced diet containing whole wheat flour, glycerol, and Brewer’s yeast, or a third minimal diet of only whole wheat flour. : experience in the former Soviet union, China, United States and western Europe.
