Metodologia para infestação da pérola-da-terra em plantas de videira utilizando Linepithema micans (Forel)sob condições controladas.

Um dos grandes desafios para a realização de estudos referentes à pérola-da-terra tem sido executar a infestação das plantas de videira em condições controladas. Este Comunicado Técnico tem como objetivo descrever uma metodologia para a infestação da cochonilha em mudas de videira utilizando ?Gaiolas de Gallotti? com auxílio da formiga L. micans.bitstream/item/69374/1/cot117.pd

Avaliação de inseticidas e iscas tóxicas para o controle de Linepithema micans na cultura da videira.

O objetivo deste trabalho foi avaliar o efeito de inseticidas e formulações de iscas tóxicas visando ao controle de L. micans.Resumo

Effect of insecticides sprayed on leaves and applied via soil to Aphis illinoisensis Shimer, 1866 (Hemiptera: Aphididae) on grapevines.

High infestations by the grapevine aphid Aphis illinoisensis (Hemiptera: Aphididae) have been observed in vineyards in southern Brazil, retarding plant growth and causing premature berry drop. This study evaluated the effect of insecticides on the control of the species in two experiments carried out in a greenhouse. The first control experiment for A. illinoisensis was conducted with seedlings of Vitis vinifera var. ‘Cabernet Franc’ to assess the effect of azadirachtin (Azamax®) at dosages of 2.4 and 3.6 mL a.i. (active ingredient)/100 L of water, with reapplication seven days after the first application (DAFA). To compare its effect, the neonicotinoids imidacloprid (Provado 200 SC®) and thiamethoxam (Actara 250 WG®) were sprayed at dosages of 8 mL or g a.i./100 L of water in foliar application without reapplication. The second experiment compared the effect on A. illinoisensis by spraying these neonicotinoids at dosages of 8 mL or g a.i./100 L in foliar applications and of 0.05 mL or g a.i./100 L applied in the soil. Evaluations were performed at 0, 1, 5, 7, 10 and 14 DAFA. Imidacloprid and thiamethoxam effectively controlled A. illinoisensis in both forms of application [soil and foliar], while azadirachtin at the dosage of 3.6 ml a.i./100 L reapplied seven days after the first application provided 55.7% control. In conclusion, A. illinoisensis can be controlled effectively by employing neonicotinoids in the soil, while azadirachtin can be an alternative to reduce infestation pressure.
