Development of Nanocomposite Bioactive Diffusion Films (BDFs) Combined With Gamma Irradiation for Control of the Rice Weevil Sitophilus oryzae, a Stored Product Pest.
Article in Journal of food science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The fumigant toxicity of 6 essential oils (EOs) (Mediterranean, Southern, citrus, cinnamon, Asian, and savory thyme), 2 citrus extracts (CEs: organic OCE and natural NCE), and 2 active formulations (microfluidized nanoemulsions AF-1 and AF-2) was investigated for control of rice weevil (Sitophilus oryzae), a stored product pest. In bioassays, AF-1 and AF-2 at 0.6 µL/mL exhibited higher insecticidal efficacy compared to single EOs and CEs after 72 h of exposure. AF-2 showed higher acetylcholinesterase enzyme inhibition in rice weevils than AF-1. Oil-in-water nanoemulsions (NEs) of AF-1 and AF-2 were prepared by microfluidization, resulting in a decrease in droplet size (DS) from 232 to 116 nm and 230 to 40 nm, and an increase in encapsulation efficiency (EE) from 30% to 77% and from 11% to 79% respectively. To exploit the insecticidal attributes of these NEs, 6 nanocomposite bioactive diffusion films (BDFs) were prepared based on chitosan (CH), poly(butylene adipate-co-terephthalate (PBAT), or polylactic acid (PLA), all reinforced with cellulose nanocrystals (CNC), and containing either AF-1 or AF-2. Films were evaluated as diffusion devices in bags of rice infested with weevils. CH films induced the highest insect mortality (78%-83%) after 14 days, compared to 6% in controls. Gamma irradiation at 200 Gy alone caused 62% mortality, which increased to 82%100% after combination with the BDFs after 14 days. The presence of CNC in BDFs reduced the % release of bioactive NEs by 12%-27% compared to the films without CNC. PRACTICAL APPLICATIONS: Nanocomposite BDFs developed in this study could be applied as diffusion devices of insecticidal natural compounds for the control of rice weevils in packaged rice. The active formulations (AF-1 and AF-2 based on nanoemulsions of CEs and EOs), combined with low-dose irradiation treatments, could be used in the food industry for controlling insect proliferation in the sector of stored cereals.
