Development of Bemisia tabaci (biotype Q) on tomato cultivars with/without the Mi gene
Year: 2000
Type: article
Abstract: No differences were found in female longevity when comparing the four cultivars. However, females on cultivars with the Mi gene lived significantly longer (31.94 days) than on cultivars without it (22.87 days). Males lived 17 days as an average; the differences observed in male longevity were not related with the presence of the Mi gene (Roma < Motelle < Moneymaker = Ronita). The number of eggs laid per female did not differ between cultivars. It ranged between 85 for Roma and 126 for Moneymaker, with an average value of 113 eggs per female. Mortality of immatures was also similar for the four cultivars, the average percentage of eggs that reached the adult stage being 82%. The total time of development from egg to adult differed when comparing the four tomato cultivars (Roma < Motelle < Ronita = Moneymaker. The average values were (in days): 28.7 (Roma), 29.5 (Motelle), 27.6 (Ronita) and 26.1 (Moneymaker). However, the difference was not associated to the presence of the Mi gene. Significant differences were also observed in some intermediate times: from egg to larva (Roma = Motelle < Ronita = Moneymaker) and from larva to pupa (Roma = Motelle < Ronita < Moneymaker), these differences also bearing no relation to the presence of the Mi gene.
