Resumo:
The indiscriminate use of pesticides has caused several environmental problems.
as contamination of soil, water and ecosystems. In search of alternatives
pest control in stored seeds, many researchers have
dedicated to the study of plant extracts and oils, which contain substances
bioactive substances known as secondary metabolites. The gift was made with the
objective of showing the importance of pest control using extracts from
botany. Plant extracts are liquid or powdery preparations obtained by removing
active principles of vegetables by some methodologies, which have as their
purpose to concentrate insecticidal substances on insect control
in stored seeds. The leaves of the species of Cinnamomum were used.
zeylanicum and Cymbopogon winterianus on Sitophilus zeamais adult in corn
Aztec variety and the effect of these products on the physiological quality of seeds
in storage. Extracts at doses of 3, 6, 9 and 12 mL were used on the
adult insects through a potter tower, getting the best doses to inhibit
the development of insects during the 120 days of storage,
satisfactory results in insect control at doses 6, 9 and 12
mL, without affecting germination during seed storage
in two inoculated processes (with 30 adult insects in each container) and not
inoculated. Repellency was evaluated using an arena with source powders.
tense vegetable was evaluated the effect associated with repellency / attractiveness and mortality
of adults of Sitophilus zeamais. In this test we used seed samples
ground corn 10 and 0.3 g of plant powders. In each box, 30
adult insects, with four repetitions for each treatment. These results
showed that citronella and cinnamon can be used as a plant insecticide in the
control of Sitophilus zeamais in the storage of corn seeds,
A more efficient study with phytochemical analysis of
better proof of its chemical constituents with insecticidal action.
