- Abstract
Research has been conducted in a laboratory environment about the impact of an aqueous extract of green vegetative parts - leaves and stems of tomato plants concerning tobacco aphids from the species Myzus persicae Sulzer. The dynamics of limiting the representatives of aphids in small-leaf tobacco Dupnitsa 733 and large-leaf tobacco type Virginia line 0842 were monitored and compared. They are used biologically clean tomato plants to avoid possible contamination when used to treat the relevant crops. The green vegetative parts were exposed into water in three different time periods. The bioinsecticidal effect of the tomato extract was established when applied in different еxposures against M. persicae. The highest efficacy was found during treatment with the highest exposure. Despite the reported good laboratory results of the tomato extract, as a bioinsecticide against leaf aphids M. persicae, it is necessary to test its effectiveness in field conditions. This will establish its influence on the beneficial entomofauna and in particular on the honey bee Apis mellifera L.
