![]() Bee visitors of quaresmeira flowers (Tibouchina granulosa Cogn.) in the region of Dourados (MS-Brasil). Environmental Toxicology and Chemistry, 35: 144-51. Effects of the herbicide dicamba on nontarget plants and pollinator visitation. It was observed that the incidence of pollinator insects varied according to cultivars and herbicides tested however, the PowerCore® genotype experienced more visitation of pollinating bees independently of the herbicide treatments.īohnenblust, E.W., Vaudo, A.D., Egan, J. Apis mellifera (L.) (Hymenoptera: Apidae), Tetragonisca angustula (L.) (Hymenoptera: Apidae) and Trigona spinipes (F.) (Hymenoptera: Apidae) were the pollinator species identified in the crop. In order to evaluate the presence of insects, a zig-zag tour was carried out throughout the experimental field, ascertained from visual analysis and direct counting of six plants per plot (the dimensions of the plots were 2.5 x 10 m with five maize lines spaced 0.50 m between rows and 0.36 m between plants) randomly, 18 days after spraying herbicides in the area. The aim of this research was to verify the impact of genotypes of genetically modified maize, Herculex®, PowerCore®, and the conventional isohybrid, pulverized or not with herbicides (atrazine, glufosinate-ammonium and nicosulfuron) in bee populations. ![]() There is little information on the effects of Bt transgenics and their cultural practices on the behavior of pollinators in genetically modified crops. Non-target insects end up being exposed to Bt proteins and herbicide applications. ![]() In addition, these plants have been stacked with different herbicide tolerance genes. Cry proteins derived from the bacterium Bacillus thuringiensis (Bt) have been widely used in transgenic maize due to their toxicity and specificity against insects that damage crops.
