Eicosanoids: Exploiting Insect Immunity to Improve Biological Control Programs

Insects, like all invertebrates, express robust innate, but not adaptive, immune reactions to infection and invasion. Insect immunity is usually resolved into three major components. The integument serves as a physical barrier to infections. Within the hemocoel, the circulating hemocytes are the temporal first line of defense, responsible for clearing the majority of infecting bacterial cells f...

Eicosanoids influence insect susceptibility to nucleopolyhedroviruses.

Nine pharmaceutical inhibitors of eicosanoid biosynthesis (e.g., bromophenacyl bromide, clotrimazole, diclofenamic acid, esculetin, flufenamic acid, indomethacin, nimesulide, sulindac, tolfenamic acid) that increased the susceptibility of the gypsy moth, Lymantria dispar (L.), to the nucleopolyhedrovirus LdMNPV were tested against the beet armyworm Spodoptera exigua (Hübner), the corn earworm H...

Eicosanoids mediate insect hemocyte migration.

Hemocyte migration toward infection and wound sites is an essential component of insect defense reactions, although the biochemical signal mechanisms responsible for mediating migration in insect cells are not well understood. Here we report on the outcomes of experiments designed to test the hypotheses that (1) insect hemocytes are able to detect and migrate toward a source of N-formyl-Met-Leu...

Exploiting genomics to improve the biological control potential of Pasteuriaspp.an organism with potential to control plant-parasitic nematodes

The Pasteuria group of Gram positive bacteria are invertebrate parasites with the potential to be developed into biological control agents of plant-parasitic nematodes. A key step in the infection process is the attachment of endospores to the cuticle of plant-parasitic nematodes, possibly through a Velcro-like attachment system involving the collagen-like fibres of the exosporium (Davies, 2009...

Eicosanoids mediate insect nodulation responses to bacterial infections.

We propose that nodule formation is mediated by eicosanoids in insects. Nodulation is the temporally and quantitatively predominant cellular defense response to bacterial infection in insects and other invertebrates. Inhibition of eicosanoid biosynthesis in larvae of the tobacco hornworm Manduca sexta immediately prior to intrahemocoelic infections with the bacterium Serratia marcescens strongl...
