“…The selection of Trichogramma spp. and/or strain(s) has been one of the widely studied factors, as quality characteristics in biological control programs (Hassan, 1997;Venkatesan & Jalali, 2013;Paes, Lima, Pratissoli, Carvalho, & Bueno, 2018). Thus, the results obtained in the present work demonstrate the importance of selection of strains of this parasitoid for the management of tomato-borer, since there are differences for the parameters evaluated in the species and/or tested strains, since the host is a factor that can provide behavioral changes in this egg parasitoid (Pratissoli et al, 2003;Goulart, Bueno, Bueno, & Diniz, 2011;Hou et al, 2018).…”

The tomato is a crop of great importance for Brazilian agriculture. Among the most damaging pests, the small tomato borer, Neoleucinodes elegantalis Guenée (Lepidoptera: Crambiadae) has caused great losses, since they directly reach the fruits to be commercialized, being used for its handling a large volume of insecticides. In this way, the use of alternative techniques that help in the management of this pest becomes of great importance. Among them, the use of the egg parasitoid Trichogramma spp. has been promising. Thus, the present study aimed to evaluate the performance of Trichogramma species and/or strains in N. elegantalis by selection of strains. The selection was made based on four lineages maintained in the Nucleus of Scientific and Technological Development in Phytosanitary Management of Pests (NUDEMAFI), being three strains of the species T. pretiosum and one of T. galloi species. The parameters evaluated were percentage of parasitized eggs, egg viability, number of individuals per eggs, sex ratio and number of Trichogramma spp. to be released. The T. galloi (T. g1) showed the best parameters for selection of the strain. Estimating the optimal number of T. g1 in eggs of small-fruit-borer was 82 individuals per egg parasitoid. Therefore, this strain was selected for the management of the small tomato-borer, whose eggs presented favorable physicochemical characteristics for the development of the parasitoid.

“…Similarly, Perveen et al (2012) reported that maximum parasitization of T chilonis was observed on C. cephalonica eggs (84.3 per cent) at 28°C. Venkatesan & Jalali (2013) also observed that the effects of the two physical factorstemperature and humidity on the biology of Trichogramma have shown that temperature below 15 or above 35 °C tends to cause mostly negative effects on their survival and/or performance. The findings of present study made it clear that 25°C is best suited for the highest per cent parasitisation and yielded maximum adults of T. chilonis.…”

The objective of this work was to determine the biological parameters and thermal requirements of Trichogramma chilonis strain reared on Corcyra cephalonica and Plutella xylostella eggs at College of Agriculture, CAU, Imphal, Manipur. The optimum temperature for the parasitism and emergence of T. chilonis was 25°C and the utmost longevity was found at the same temperature. Maximum parasitism was observed 84.14 and 82.71 per cent at 25°C, while minimum parasitism was 76.57 and 69.14 per cent at 20°C on C. cephalonica and P. xylostella eggs, respectively. The results indicate that temperature has a significant effect on the biological parameters of T. chilonis and with increasing temperature developmental duration decreased in laboratory condition of Manipur. On the basis of the present results Corcyra cephalonica eggs was more suitable for mass production of T. chilonis than P. xylostella under controlled conditions.
