Volatiles from (Lepidoptera, Crambidae) host plants influence olfactory responses of the parasitoid (Hymenoptera, Braconidae, Agathidinae).

Biol Control 2019 Mar;130:104-109

International Institute of Tropical Agriculture, Benin Research Station (IITA-Benin), 08 BP 0932 Tri Postal, Cotonou, Benin.

Plants damaged by herbivores are known to release odors attracting parasitoids. However, there is currently no information how leguminous plants damaged by the pod borer attract the exotic larval parasitoid , which was imported into Benin from the putative area of origin of the pod borer in tropical Asia for assessing its potential as a biological control agent. In this study, we used Y-tube olfactometer bioassays to investigate response towards odors emitted by four -damaged host plants: cowpea , the most important cultivated host, and the naturally occurring legumes and .

Root environment is a key determinant of fungal entomopathogen endophytism following seed treatment in the common bean, .

Biol Control 2018 Jan;116:74-81

Sustainable Perennial Crops Laboratory, United States Department of Agriculture, Agricultural Research Service, Beltsville, MD 20705, USA.

The common bean is the most important food legume in the world. We examined the potential of the fungal entomopathogens and applied as seed treatments for their endophytic establishment in the common bean. Endophytic colonization in sterile sand:peat averaged ca. Read More

and endophytically colonize cassava roots following soil drench inoculation.

Biol Control 2016 Apr;95:40-48

Entomology, International Center for Tropical Agriculture (CIAT), km. 17, Recta Cali-Palmira, Colombia; Life Sciences Innovation Center, University of California, Davis - Chile, Andrés Bello 2299 No. 1102, Providencia, Santiago, Chile.

We investigated the fungal entomopathogens and to determine if endophytic colonization could be achieved in cassava. An inoculation method based on drenching the soil around cassava stem cuttings using conidial suspensions resulted in endophytic colonization of cassava roots by both entomopathogens, though neither was found in the leaves or stems of the treated cassava plants. Both fungal entomopathogens were detected more often in the proximal end of the root than in the distal end. Read More

Benefits of self-superparasitism in a polyembryonic parasitoid.

Biol Control 2008 Aug;46(2):133-139

Entomology Department, University of Minnesota, 219 Hodson Hall, 1980 Folwell Avenue, St. Paul, MN, 55108.

is a polyembryonic parasitoid, with embryos that divide asexually within the host (European corn borer, ) to produce broods of clonal offspring. From a biological control standpoint, polyembryony seems advantageous because each parasitized host yields multiple parasitoids with minimal time and egg investment. When we observed in the field, however, we found that the parasitoid virtually always invested additional time and, if possible, stings into hosts that it had already stung, apparently reducing some of the advantages of polyembryony.
