Volatile Infochemicals from Rhyzopertha dominica Larvae and Larval Feces Involved in Theocolax elegans Host Habitat Location

Abstract: The development of biologically based approaches for stored product pest control is needed to reduce chemical inputs. Bioassays were performed to investigate host habitat location in the trophic interaction durum wheat/Rhyzopertha dominica/Theocolax elegans. GC-MS analyses were carried out to identify some chemical compounds produced by the host-related substrates. Choice and no-choice experiments demonstrated that female parasitoids were poorly attracted to intact kernels with respect to the infested substrat… Show more

“…Several species of caterpillars, which live in stationary leaf shelters, have also evolved behaviors such as “ballistic frass ejection,” shooting fecal pellets ( Fig 1 ) to remarkable distances, successfully avoiding accumulation of fecal material and subsequent need for removal [ 3 ]. While feces avoidance mostly seems to benefit invertebrates by preventing disease, it is not the only benefit—predatory and parasitic wasps seem to have the ability to use volatile chemicals from frass to locate their host species [ 4 , 5 ], and some lepidopteran and coleopteran species have shown oviposition avoidance in areas that have been treated with feces-associated volatiles of their own species and that of others, potentially saving their offspring from future competition [ 6 , 7 ].…”
