“…Apart from the species recorded by Foerster & Avanci (1999), two other Trichogramma species were collected in A. gemmatalis eggs, namely T. acacioi Brun, Moraes &Soares, 1984 andT. lasallei Pinto, 1998.…”

“…Until 1997 there was only one report on the incidence of egg parasitoids in eggs of A. gemmatalis (Hohmann et al 1989). Polaszek & Foerster (1997) described Telenomus cyamophylax Polaszek, 1997 from eggs of A. gemmatalis andAvanci (1999) reported the occurrence of Trichogramma pretiosum Riley, 1879, T. rojasi Nagaraja &Nagarkatti, 1973 andT. atopovirilia Oatman &Platner, 1983 parasitizing eggs of the velvetbean caterpillar.…”

T. pretiosum and T. acacioi accounted for more than 80% of the parasitoids emerged each year, followed by T. atopovirilia, T. rojasi and T. lasallei, with less than 20% of incidence. Both the sex ratio and the mean number of parasitoids/egg did not differ among the species. Searching for A. gemmatalis eggs proved to be time consuming in comparison to the collection of eggs laid by moths inside the cages, which showed to be a useful method to provide qualitative estimates of parasitism in eggs of A. gemmatalis.

“…For these reasons, states such as Rio Grande do Sul (Costa & Link, 1974), Paraná (Corrêa-Ferreira et al, 1998;Foerster & Avanci, 1999), São Paulo (Campos et al, 1997), Mato Grosso do Sul (Godoy et al, 2005), Minas Gerais (Venzon et al, 2000), Distrito Federal (Medeiros et al, 1997) and Acre (Thomazini, 2001) have developed research on species of insect pests and natural enemies, aiming at the implementation of biological control programs.…”

“…Currently, there are 190 known species of Trichogramma, and 38 of these occur in South America, 28 of which have been recorded in Brazil (Moreira et al, 2009). Despite the importance of soybean production in the state of Mato Grosso, no research has been carried out in the state regarding the occurrence of egg parasitoids, although their effectiveness has been proven by previous research (Foerster & Avanci, 1999;Foerster & Butnariu, 2004).…”

Occurrence of parasitoids in eggs of soybean lepidopteran pests, such as velvetbean caterpillar, soybean loopers and others the genus Spodoptera and Helicoverpa in Mato Grosso, Brazil was studied. Due to the scarcity of information on the natural occurrence of parasitoids in lepidopteran eggs in soybean fields in Mato Grosso surveys were conducted in Tangará da Serra to verify the occurrence these parasitoids. Surveys were conducted in two areas in Tangará da Serra, with a total of 591 eggs, of which 138 and 77 eggs were collected in area I and 274 and 102 eggs in area II, during the 2008/2009 and 2009/2010 soybean seasons, respectively. From the eggs collected in area I, 26.6% were parasitized in the first year and 30.0% in the second season. In area II, the parasitism rates were 40.2% and 27.5% for the first and second season respectively. The species of parasitoid collected was Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) totaling 354 parasitoids. We conclude that there is a natural occurrence of T. pretiosum, this being the species of egg parasitoid found, and that parasitism rates were higher when compared with other studies under natural conditions, especially considering the large number of chemical products used in the fields. The identification of the eggs parasitoids in Mato Grosso State is important to development of biological control programs for lepidopteran pests.
