Nonpreference by the sorghum midge Contarinia sorghicola (Coquillett),has been reported in the literature as an important mechanism of resistance of sorghum in many different resistance sources. This mechanism, in the case of sorghum and sorghum midge interactions, can be approached in two different steps: monpreference for adult visitation and nonpreference for adult visitation and monpreference for oviposition. Assuming equivalent number of flowers per panicle to be compared, nonpreference for visitation in related to the number of oviposition females present per panicle. On the other hand, nonpreference for oviposition is related to the number of eggs laid between the spikelets glumes under even infestation levels of adults. Using resistant(ATx2755 x RTx2767) and susceptible (ATx2752 x RTx430) sorghum hybrids, the sorghum midge adult nonpreference for visitation and nonpreference for oviposition were assessed at College Station, Texas, under field conditions during the summer of 1983 and 1984. The mean number of oviposition females trapped per flowering panicle of both hybrids was recorded in 5 trials in 1983 and 2 trials in 1984. During late morning, about ten panicles per hybrid in each trial were bagged with four-liter plastic bag, excised, and transported to the laboratory where the nunber of visiting females on each panicle was counted. |
