Stimulation of oviposition in the seed-corn maggot fly, hylemya cilicrura (rond.) (diptera: anthomyiidae)¹
1965
BARLOW, C.A.
Experiments to determine some of the factors which stimulate oviposition in Hylemya cilicrura and the general location of receptors of oviposition stimuli are described. Females are stimulated to oviposit by moist soil and by certain types of vegetative matter in the soil, including seeds planted under the surface. These substances are detected by olfaction and perhaps, in some cases, by contact stimulation. Receptors of oviposition stimuli are located chiefly on the antennae but also at other loci on the body. The number of eggs laid depends on the presence of suitable oviposition sites and the intensity of stimulation derived from the sites. Substrate texture may also influence the number of eggs laid. These facts are discussed in relation to oviposition and distribution of the species in the field.
