“…Parasitism by Trichogramma was observed in fields planted with fruit and vegetable crops in Minas Gerais State, as had been observed in other studies in Eucalyptus-growing areas (Zanuncio et al 2009;Macedo-Reis et al 2013). Natural parasitism of pest Lepidoptera eggs by Trichogramma species was verified in 6 of 9 of the plant species in the sampled agricultural ecosystems.…”

“…The taxonomy of Trichogramma is fundamentally important for the maintenance of these natural enemies in agricultural areas and for the establishment of integrated pest management programs that use these wasps as agents of biological control. Few studies on the native species of Trichogramma in the State of Minas Gerais, Brazil, have been published (Murta et al 2008;Zanuncio et al 2009;Macedo-Reis et al 2013). The northern region of Minas Gerais has a semiarid climate and a diverse range of agricultural crops, and the composition of its native fauna is not completely known.…”

“…A mosaic landscape composed of both cultivated and fragments of native vegetation can create multiple habitats for the breeding, feeding and sheltering of the natural enemies [ 7 , 43 ]. This can improve the environmental stability in the homogeneous stands [ 18 ], and reduce the lepidopteran defoliator populations in the forest plantations [ 44 ]. Areas of the native vegetation between the forest plantations is a technique of the integrated management of insect pests in the eucalyptus plantations in Brazil [ 45 ], in which the study area included about 46.87% of its surface with preserved native forest among the eucalyptus stands.…”

“…Parasitoids reduce number of pest rather than controlling [ 2 , 3 ]. Therefore, the maintenance of the understory and preservation of the remnant of the native vegetation in the eucalyptus plantations have been promoted to increase the invertebrate communities with the potential for biological control [ 17 , 18 ]. Parasitism is normally higher in the diverse landscapes due to the greater number of nectar sources and microclimates [ 19 , 20 ].…”

Can the Understory Affect the Hymenoptera Parasitoids in a Eucalyptus Plantation?

The understory in forest plantations can increase richness and diversity of natural enemies due to greater plant species richness. The objective of this study was to test the hypothesis that the presence of the understory and climatic season in the region (wet or dry) can increase the richness and abundance of Hymenoptera parasitoids in Eucalyptus plantations, in the municipality of Belo Oriente, Minas Gerais State, Brazil. In each eucalyptus cultivation (five areas of cultivation) ten Malaise traps were installed, five with the understory and five without it. A total of 9,639 individuals from 30 families of the Hymenoptera parasitoids were collected, with Mymaridae, Scelionidae, Encyrtidae and Braconidae being the most collected ones with 4,934, 1,212, 619 and 612 individuals, respectively. The eucalyptus stands with and without the understory showed percentage of individuals 45.65% and 54.35% collected, respectively. The understory did not represent a positive effect on the overall abundance of the individuals Hymenoptera in the E. grandis stands, but rather exerted a positive effect on the specific families of the parasitoids of this order.

“…At least 12 native lepidopteran species (leaf chewers) feeding on introduced eucalypts have been associated with one or more natural enemies, mostly parasitoids. The majority of records are from Brazilian eucalypt plantations (e.g., de Campos and Cure, 1992; de Oliveira et al, 2000; Macedo-Reis et al, 2013) but there are also examples from East Africa, India, and Malaysia (Okelo, 1972; Joshi et al, 1988; Speight and Wylie, 2001). The predatory pentatomids ( Podisus spp.)…”

New Communities on Eucalypts Grown Outside Australia

The expansion of eucalypt forestry worldwide has been accompanied by accidental and deliberate introductions of Australian insects associated with eucalypts. Local insect species have also colonized introduced eucalypts in many regions. This situation provides a unique opportunity to observe the development of new insect communities across trophic levels. Here the history of Australian invaders and native colonizers on eucalypts outside Australia is reviewed from the perspective of herbivore guilds: leaf chewers, sap suckers, wood borers, gall formers, termites. Historical patterns of invasion are identified across these guilds. Very few species of Australian leaf chewers, wood borers or termites have become widespread but these guilds are proportionately high in native colonizers. In contrast, sap suckers have multiple invasive species globally with relatively fewer native colonizers. The gall former guild also has several invasive species but so far includes no native colonizers, perhaps due to their tendency to have highly specific host plant associations. Natural enemies of Australian invaders are also members of new eucalypt insect communities, partly through planned biological control programs, but the rate of accidental introductions at higher trophic levels is increasing steadily. At the same time, local natural enemies enter eucalypt communities either to form new associations with Australian invaders or to follow native colonizers into this new habitat. Australian sap suckers have attracted far more new associations than other guilds so far. Native leaf chewers have often been followed by their local natural enemies into eucalypt communities, particularly in Brazil. Generally there are fewer records relating to local natural enemies and their role in new eucalypt communities. The complexity of new eucalypt communities outside Australia is expected to increase in future.
