Influence of host origin on host choice of the parasitoid Dinarmus basalis: does upbringing influence choices later in life?

Sankara F, Dabiré LC, Ilboudo Z, Dugravot S, Cortesero AM, Sanon A - J. Insect Sci. (2014)

Bottom Line: In the three-dimensional system, the females from the four strains did not appear to have any preference for a given type of seed containing 4(th)instar larvae or pupae.These results show that the use of D. basalis as a biological control agent is possible in host changing situations where C. maculatus starts to attack other legumes.The results of this study also provide information supporting the behavioral plasticity of D. basalis.

Response (time in seconds in each branch) of naïve females of four strains of Dinarmus basalis in a Y-tube olfactometer disseminating pure air and odorous air. Means ± SE differed significantly according to the t-test of paired series at the significance level of 5%. Cw = odor of cowpea seeds (Vigna unguiculata); Bw = odor of white Bambara groundnut seeds (Vigna subterranea); Bs = odor of striped Bambara groundnut seeds (V. subterranea); Pp = odor of pigeon pea seeds (Cajanus cajan). High quality figures are available online.

Mentions: When D. basalis females from all four strains had a choice between pure air and air containing odors from seeds containing 4th instar larlarvae or pupae of their plants of origin, they were attracted to the odorous air, where they spent significantly more time (p < 0.01) (Figure 1).
