Effect of Nitrogen on Stored-Product Insect Control at Industrial Scale

SIMPLE SUMMARY: Nitrogen treatment is a promising method for controlling stored product insects. It is based on the alternation of the oxygen level in the atmosphere (lower than 3%), which can be lethal to insects. In the present study, we tested nitrogen treatment (>99%) on a commercial scale to...

description SIMPLE SUMMARY: Nitrogen treatment is a promising method for controlling stored product insects. It is based on the alternation of the oxygen level in the atmosphere (lower than 3%), which can be lethal to insects. In the present study, we tested nitrogen treatment (>99%) on a commercial scale to control major stored product insects such as Sitophilus granarius (L.), Sitophilus oryzae (L.), Rhyzopertha dominica (F.), Prostephanus truncatus (Horn), Tribolium confusum Jacquelin du Val, and Oryzaephilus surinamensis (L.). The current work indicates that nitrogen treatment is effective for all life stages and populations tested. ABSTRACT: In this study, we evaluated the insecticidal effect of nitrogen against Sitophilus granarius (L.), Sitophilus oryzae (L.), Rhyzopertha dominica (F.), Prostephanus truncatus (Horn), Tribolium confusum Jacquelin du Val, and Oryzaephilus surinamensis (L.). Four trials were conducted in chambers containing flour in bags or sacks with >99% nitrogen level. Adults of all the above species, as well as immature life stages (eggs, larvae, and pupae) of T. confusum were used in the trials. Our results showed that nitrogen caused high mortality for all species and life stages tested. Some survival was recorded for R. dominica and T. confusum pupae. Low progeny production was recorded for S. granarius, S. oryzae, and R. dominica. In conclusion, our trials indicated that a high nitrogen environment can provide satisfactory control of various primary and secondary stored-product insect species.
