“…According to GONDIN (1984), Lepidoptera and Coleoptera represented 38% of guarana floral visitors, and these are the most frequent hosts of Ichneumonidae. Only Brachycyrtinae, Diplazontinae, Neorhacodinae and Orthocentrinae do not include these orders among their hosts (FERNÁNDEZ-TRIANA;RAVELO, 2007).…”

Ichneumonidae are solitary parasitoids that mainly attack larvae and pupae of Lepidoptera, Coleoptera and Hymenoptera, which constitute important agricultural pests. The objective of the present paper was to characterize the assemblage of Ichneumonidae associated to the conventional and organic cultivation of Guarana (Paullinia cupana) crop in Manaus City (Amazonas State, Brazil) with faunistic analysis. The samples were collected at Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), using Malaise and Moericke traps, between September 2012 and February 2013. We collected 296 specimens of Ichneumonidae, represented by 14 subfamilies, 41 genera and 63 morphospecies. The faunistic analysis revealed the predominance of rare and less frequent genera (54.2% in conventional and 47.1% in organic crop management). Venturia Schrottky was highlighted as superabundant, super frequent and constant (46.4% of the specimens) in conventional cultivation. In organic cultivation, Eiphosoma Cresson (15.6% of the specimens), Venturia (15.1%), Polycyrtidea Viereck (7%), Stethantyx Townes (6%), Enicospilus Stephens and Diapetimorpha Viereck (both 5.5%), Polycyrtus Spinola and Podogaster Brullé (both 5%) were more abundant, more frequent and constant. The observed differences reflect the type of crop management. Considering that organic crop management do not use agrochemicals, there is a greater diversification of the landscape. On the other hand, a reduction in richness and abundance has been observed in conventional crop management, due to its greater alteration and uniformity of the landscape. This study evidences a high number of rare, less frequent and accidental genera, and reveals the predominant groups in each crop cultivation system.

Eiphosoma laphygmae, a classical solution for the biocontrol of the fall armyworm, Spodoptera frugiperda?

The fall armyworm, Spodoptera frugiperda, an American Lepidoptera, is invasive in Africa and Asia and currently one of the most damaging cereal pests in the tropics. The ichneumonid parasitoid, Eiphosoma laphygmae, is a potential classical biological control agent. We assessed existing knowledge on biology, identified natural distributions, collated reported parasitism rates from field studies and determined which other parasitoids co-occurred. We discussed the suitability of E. laphygmae for classical biological control as well as identified limitations and knowledge gaps. We conducted a systematic literature review and had 185 hits, retaining 52 papers. Reports on the natural distribution of E. laphygmae were restricted to the American tropics, ranging from North-East Mexico to Sao Paulo State, Brazil. There were only two single and unconfirmed records of it on other hosts, suggesting that the parasitoid may be specific to S. frugiperda, but this needs confirmation. In fields where E. laphygmae occurred naturally, it was the second most important contributor to fall armyworm mortality, after the braconid Chelonus insularis. On average, E. laphygmae parasitized 4.5% of fall armyworm in field studies. The highest parasitism rates were from Costa Rica (13%) and Minas Gerais, Brazil (14.5%). However, these parasitism rates are probably largely underestimated because of likely biases in sampling and parasitism rate calculations. Eiphosoma laphygmae appeared to establish better in more diverse, weedy systems. As African farming systems often have high diversity, this may favour the establishment and parasitism of E. laphygmae if eventually introduced as a classical biological control agent.

A taxonomic study of the species of the Darwin wasp genus Eiphosoma Cresson, 1865 (Hymenoptera: Ichneumonidae: Cremastinae) from the department of Caquetá, Colombia, resulted in five new species being described: E. caqueta sp. nov. (Type locality: Curillo, Caquetá), E. eneke sp. nov. (Type locality: San Vicente del Caguán, Caquetá) E. interpunctum sp. nov. (Type locality: Solano, Caquetá,), E. rumi sp. nov. (Type locality: Florencia, Caquetá) and E. sinecarenatum sp. nov. (Type locality: Florencia, Caquetá). With this paper, the number of Eiphosoma species from Colombia increases from three to 16. Eiphosoma bogan Gauld, 2000; E. dentator (Fabricius, 1804); E. dolopon Gauld, 2000; E. fluminense Costa Lima, 1953; E. fuzhi Gauld, 2000; E. macrum (Enderlein, 1921); E. minense Costa Lima, 1953 and E. tantalium Gauld, 2000 are recorded for the first time from Colombia. A dichotomous key to the Colombian species is presented.
