  • These results support our hypothesis, showing that SeiPLA2-A predicted from the transcriptome analysis catalyzes hydrolysis of fatty acids from cellular PLs and plays crucial physiological roles in insect immunity and development. (usda.gov)
  • beetle
  • The first insect released was the melaleuca snout beetle or weevil, Oxyops vitiosa (Pascoe) (Insecta: Coleoptera: Curculionidae) (Figure 2). (ufl.edu)

  • infection
  • This finding will impact scientists working on how an insect resists infection because it begins to explain, along with other studies in the field, why some infections are fatal while others are not and how baculoviruses can be made more useful as a control measure in the field. (usda.gov)
  • A significant difference was found in the bound/free ratio of 59Fe (large protein bound Fe: small protein bound and/or free Fe) between control and baculovirus infected hemolymph at 60 h post-infection indicating that Fe released from damaged cells is taken into hemolymph not as free Fe. (usda.gov)
