“…However, due to their small size, species of Trichogramma can potentially be transported by wind and intentionally or otherwise, by man from one country to another in a short period of time. Because of this it is often difficult to determine individual species' natural range of distribution (Querino et al, 2010).…”

“…Trichogramma occurs in all vegetated terrestrial habitats that have been sampled in all six biogeographic regions: Palearctic, Oriental, Nearctic, Neotropical, Afrotropical and Australasian (Querino et al, 2010). T. brassicae was isolated from several host species (Pintureau, 2011).…”

European corn borer (Ostrinia nubilalis) (ECB) is an important maize pest in central and northern Europe. Presently it is controlled by insecticides or biological agents such as Trichogramma brassicae in several European countries, excluding Slovenia, where the pest's pressure is highly variable and no appropriate mechanization is available. Lessening the dependence on chemical pesticides is an integral part of the European Union's agenda for agriculture. Mass release of Trichogramma spp. could be seen as a promising alternative for ECB control in countries with a highly fluctuating ECB pressure and no mechanization for insecticide applications. However, no records of naturally occurring hymenopteran parasitoids of ECB exist in Slovenia. To address this important under-researched topic and provide the expert basis for potential introduction of ECB egg parasitoids in Slovene maize production, a systematic inventarisation programme of ECB parasitoids was launched in 2010. Additionally, ECB flight was monitored in 2011 and 2012 at two locations in Slovenia: Jablje and Rakičan. In both locations two ECB generations were observed. ECB was fist observed at the end of May in Rakičan. During the five years of the systematic survey we discovered two ECB parasitoid species. ECB egg masses were parasitized by Trichogramma brassicae, whereas ECB pupae were parasitized by Tycherus nigridens, with 6 or 7 % parasitation rate, respectively. T. nigridens represents a new taxon report for Slovenia. We conclude that there is a strong need for undertaking systematic surveys of natural enemies of agricultural pests.

“…Parasitoids are key species in the regulation of insect populations (Querino et al 2010). Several species of parasitoids are used for pest management in the field, one example being the genus Trichogramma Westwood, 1833 (Hymenoptera: Trichogrammatidae), which has been reported parasitizing more than 200 species of insects that cause economic damage to crops, mainly of the order Lepidoptera (Pratissoli et al 2004, Delpuech et al 2010, Davies et al 2011.…”

Trichogramma spp. are parasitoids used in the regulation of insect populations that can cause economic damage. In order to ensure good performance, understanding some of their biological characteristics is essential. The objective of this study is to evaluate whether mating interferes with the biological characteristics of a population of Trichogramma pretiosum collected in the field. In all experiments, groups of mated and unmated females were used. We also verified any interference from mating on the biological characteristics of the offspring. We found that mating can alter the parasitism and longevity of genitor females, in addition to changing longevity among the descendants, but once parasitized, the eggs develop normally, showing similar emergence percentage and number of offspring as those from unmated females. In addition, we verified that the population of T. pretiosum collected in the field presented individuals with reproductive thelytokous and arrhenotokous characteristics. This fact highlights the importance of careful investigation on the reproduction mode of populations collected in the field, thus avoiding problems in the effective management of insect populations.

“…In total, about 35 egg parasitoid species are reported to be phoretic. Thus, from the nearly 4,000 described egg parasitoid species belonging to the two families, Scelionidae and Trichogrammatidae (Austin et al 2005;Querino et al 2010), only about 1% are known to be phoretic. The hosts they use for transport include moths, grasshoppers, butterflies, pentatomid bugs, mantids, beetles, a dragonfly, an ant, and a fly (Table 1 in supplementary material).…”

Phoretic insects utilize other animals to disperse to new environments. We recently discovered how egg parasitoids use an exciting phoretic strategy to reach egg-laying sites of their butterfly hosts. In the laboratory, female Trichogramma wasps detect and mount mated female cabbage white butterflies that emit an anti-aphrodisiac pheromone. Hardly any information exists about the natural occurrence of phoresy in wasps of this genus. Therefore, we monitored the presence of phoretic Trichogramma wasps on lepidopteran hosts in the field. Only female wasps were found at low prevalence on six lepidopteran species. Wasps were mostly found on female hosts and mainly on abundant solitary host species. This is the first report of phoretic Trichogramma wasps on butterflies in nature. We suggest that phoresy is only one of several strategies used by these polyphagous egg parasitoids. The evolution of phoresy is discussed in relation to the nutritional ecology of egg parasitoids.
