“…Fabricius are likely to be found deeper in the soil than nonparasitized grubs and that this phenomenon results from a behavioral change in the host, rather than physical actions by the wasp or its larva [ 64 ]. Also, it could be that the grub’s downward movement represents a defensive response to parasitism, because movement of parasitized grubs through the soil sometimes dislodges the egg or the developing ectoparasitic larva [ 64 , 65 ]. Nevertheless, in this work we have found that aggressive behavior against larvae of M. ruficauda is a very effective strategy in white grubs that contributes to avoid attachment of the ectoparasitic larvae to its cuticle.…”

White grubs are larvae of Coleoptera of the family Scarabaeidae. They are known because of their intensive feeding habits on crop roots. Mallophora ruficauda (Diptera: Asilidae) is a dipteran parasitoid whose larva is a natural enemy for white grubs. This species is a solitary ectoparasitoid, where both female and larva realize different steps in the host location process. Female place its eggs in high grasslands and then, the larva finds and parasitizes the host in the ground. There are nine potential hosts in the area of action of this parasitoid; however a high preference for Cyclocephala signaticollis has been observed (87% of field parasitism). It is known that many insects have developed defensive and immunological mechanisms when attacked by a parasitoid, which can be behavioral, physiological, chemical or genetic. The objectives of this work were to investigate what kind of defense and non-immunological associated mechanisms the white grubs have against this parasitoid and to understand why M. ruficauda have such a high preference for masked chafer grubs or Cyclocephala species. In particular, for each white grub species, we asked: (1) If there is a differential behavioral reaction when a parasitoid attack is simulated; (2) If body attributes of white grubs species have influence on defense behavior, and particularly for the masked chafer C. signaticollis; and (3) Why this species is the most selected by M. ruficauda. It was found that behavioral defenses of white grubs would explain the parasitism pattern of M. ruficauda larvae and its preference for C. signaticollis.

“…In Kentucky, T. vernalis was found 19.7% in P. japonica larvae in early May (Redmond and Potter, 2010). It is possible we could have missed some T. vernalis-parasitized larvae because they are often found deeper than 8 cm (Rogers et al, 2003).…”

“…Dentre os parasitoides já relatados para os corós, os mais estudados são os himenópteros do gênero Tiphia Fabricius, 1775, encontrados em larvas do besouro japonês Popillia japonica Newmann, 1838 e larvas do gênero Cyclocephala Dejean, 1821 (ROGERS; POTTER, 2004a;POTTER, 2004b;ROGERS et al, 2003). Alguns taquinídeos (Diptera) também são mencionados como parasitoides de larvas de melolontídeos (GUIMA- RÃES, 1977;HANSON, 1996;SALINAS et al, 2006).…”

RESUMO O coró-do-milho, Liogenys suturalis, tem sido observado atacando lavouras de milho, trigo e aveia no Estado de Mato Grosso do Sul. Esta praga consome as raízes das plantas prejudicando sua capacidade de absorção de água e nutrientes e, consequentemente, o seu potencial produtivo. Vários organismos podem atuar como inimigos naturais dos insetos que são tipicamente subterrâneos ou que passam uma fase do seu desenvolvimento no solo. O objetivo deste trabalho foi registrar a ocorrência e a porcentagem de parasitismo em larvas de L. suturalis coletadas em três municípios da região Sul do Estado de Mato Grosso do Sul. Foi constatada a ocorrência de parasitoides dípteros (Tachinidae) do gênero Ptilodexia Brauer and Bergenstamm, 1889 em todos os municípios onde as coletas foram realizadas. A maior porcentagem de parasitismo foi observada em Laguna Carapã (22,5%), seguida por Caarapó (15,9%) e Ponta Porã (0,8%).
