Tomato CarryingMI-1.2Gene as a Host-Plant to the Two-Spotted Spider Mite (Tetranychus urticaeKoch): Results of Laboratory EvaluationMi-1.2gene contributes to the resistance of tomato plants against some species of herbivores (i.e. nematodes, aphids) that are sap-feeders. In this study, two genotypes of tomato (Solanum lycopersicumL. syn.Lycopersicon esculentumMill.) plants with dominant (Motelle cv) and recessive (Moneymaker cv)Mi-1.2alleles were evaluated as a host-plant to the two-spotted spider mite (Tetranychus urticaeKoch, Acari: Tetranychidae). Plants were grown under glasshouse conditions. The effect of tomato genotypes onT. urticaebionomy was estimated on cut leaflets in controlled photoperiod, temperature and humidity (L/D=16/8 h; D/N temp.=23/20°C; RH=70%). Results of laboratory evaluation showed that both the bionomy and population parameters ofT. urticaereached a very similar or even higher value on plants with dominantMi-1.2allele than on plants with recessive one. A relatively high value ofT. urticaeparameters on plants resistant to root knot nematodes indicates that the mite has potential to develop rapidly. This allows the mite population to reach the density causing marked damage to plant in a short time. It is concluded that the presence ofMi-1.2gene product in tomato plants does not significantly affect the reproductive potential ofT. urticae.Therefore,Mi-1.2gene cannot be a satisfying source of plant resistance to this mite-herbivore generalist.

O objetivo deste trabalho foi avaliar os efeitos da aplicação em algodoeiros (Gossypium hirsutum L.), do ácido-fenoxibenzóico (principal subproduto da fotodegradação da deltametrina e de muitos outros piretróides) e de emulsões aquosas de Deltametrina (expostas à luz solar por dois, oito e 15 dias antes da pulverização) sobre a população do ácaro Tetranychus urticae Koch. Nas plantas pulverizadas com emulsões de Deltametrina expostas à luz solar e com ácido fenoxi-benzóico (nas maiores doses) as populações de T. urticae foram significativamente maiores que nas plantas testemunhas.
