Abstract

In order to control Spodoptera frugiperda in the maize crop in the laboratory, vegetative parts of the Edjululu-Kapassarinho plant were harvested, crushed and the concentrations formed: T0=0ml, T1=20ml, T2=40ml, T3=60ml, T4=80ml and T5=100ml. The caterpillars were collected and fasted for two hours before being placed in the treatment concentrations of each vegetative part for observation at times of 24, 48, 72, 96 and 120 hours respectively. The results showed that the fruit was the most active ingredient (Atropine, Hyoscyamine Scopolamine), followed by the stem, root and leaves, representing 60%, 27%, 24% and 13% respectively, with the leaves proving to be repellent to the caterpillars. Caterpillar mortality increased after 24 hours at all concentrations, showing 96% mortality with the stem-based extract, 98% with the leaf-based extract, 90% with the fruit-based extract and 79% with the root-based extract. In the statistical analysis observed at 5%, there was significant variation between treatments. In view of the results, the aqueous plant extract of the Endjululu-Kapassarinho plant (Datura Stramonium) proved to be effective in controlling the cartridge caterpillar in the maize crop in vitro.
