Intervention effect Mixed insect treatment caused greater grain damage.
Association Insect populations, grain damage, powder and weight loss were positively correlated.
Observation P. truncatus outnumbered S. zeamais after 60 days.
Observation P. truncatus produced 58% grain damage after 60 days in non-hermetic storage.

Other claims from this paper (6)

Intervention effect Botanical formulations reduced damage to stored maize seeds.
Intervention effect Rice husk powder yielded 85% weevil mortality.
Intervention effect Shade dried neem seed powder yielded 65% weevil mortality.
Intervention effect Sundried neem seed powder yielded a little above 40% weevil mortality, the least of the treatments.

Observation Crioulo maize had the lowest grain mass loss.
Observation Crioulo supported the least weevil growth.
Observation Bom Jesus weevils were among the populations consuming the most grain.
Observation Palmeira das Missões weevils had the lowest consumption.
