Oviposition acceptance and fecundity schedule in the cactophilic sibling species Drosophila buzzatii and D. Koepferae on their natural hosts
We tested for the occurrence of oviposition acceptance for different media prepared with cactus tissues of three alternative cactus hosts: Opuntia sulphurea, O. quimilo and Trichocereus terschekii for 4 consecutive days in lines of two Drosophila buzzatii populations and one population of D. koepfer...
