“…In addition, food irradiation is an efficient and emerging technology for pest disinfestation. A minimum dose of 400 Gray (Gy) is recommended by the USDA treatment manual for disinfestation of stored product insects, while several countries allow a dose of up to 1 kGy (Hallman, ).

The fumigant toxicity of eight individual essential oils (EOs; basil, cinnamon, eucalyptus, mandarin, oregano, peppermint, tea tree, and thyme) and one binary combination (thyme and oregano) for control of the rice weevil, Sitophilus oryzae, were investigated. In bioassays, all individual and combined EOs were toxic to the rice weevil. Eucalyptus EO exhibited the highest toxicity among the individual EO treatments, causing 100% mortality at a minimum concentration of 0.8 µL/mL after 24 hr of exposure. The combination treatment of oregano and thyme EO displayed higher fumigant activity than the individual oregano or thyme treatments. A stable oil‐in‐water nanoemulsion was evaluated using high‐pressure homogenization (microfluidization [MF]) and varying the pressure and number of cycles. The droplet size of the emulsions was found to decrease from 217 to 71 nm and encapsulation efficiency increased from 37% to 84% with increasing MF pressure and number of cycles. The optimum conditions for preparing the mixture of oregano and thyme EO nanoemulsions were evaluated to be homogenization pressure of 103 MPa and three cycles. Incorporating an oregano:thyme nanoemulsion (0.75%) into cellulose nanocrystal (CNC) containing chitosan (CH/CNC), methyl cellulose (MC/CNC), and polylactic acid (PLA/CNC) composite films resulted in extended diffusion matrices causing 32% to 51% rice weevil mortality after 14 days exposure. Irradiation at 200 Gray alone caused 79% mortality and increased to 100% when combined with the bioactive chitosan film containing the oregano:thyme nanoemulsion. Practical Application A binary combination of oregano:thyme has potential as a biopesticide against stored product pests. The encapsulation of EO nanoemulsions into biopolymeric support could be used for bioactive packaging to prevent food spoilage and extend shelf life. Combining bioactive films with irradiation can provide complete control of rice weevil in packaged rice. The system developed in this research may also be extended to explore other food‐packaging films with various food models to control different types of stored pests.

“…The use of radiation has been shown to be effective in controlling pests, causing little, or no damage to the grains (Bushra & Aslam, ). According to Hallman (), gamma radiation doses above 150 Gy were effective in controlling the pest Sitotroga cerealella by reducing the population's fecundity, decreasing the number of eggs hatched, and reducing larval growth; these effects were also inherited by the F1 progeny. Ultraviolet (UV) radiation also shows potential for insect control (Faruki, Das, Khan, & Khatun, ).…”

The objective of this study was to evaluate the effect of UV‐C radiation in controlling the maize weevils (S. zeamais Motschulsky) in stored maize. The maize and insects (adult and immature stages) were simultaneously irradiated with UV‐C dose of 10 J/cm2. UV‐C radiation can be used as control of adult weevils because it presented a lower number of live adult weevils (33.6 counts), reduction in the loss of grain mass (15 g), and fewer damaged grains (12.9%), however, not affect the control of the immature stages. The carotenoid content of maize grains was reduced after UV‐C treatment and storage. Electrical conductivity was highest in treatment without UV‐C in adult weevils owing to the higher number of insects. UV‐C radiation in pre‐storage was effective only in the control of adults; however, it is a technology free of chemical residues, allowing the processing of the grains at any time of storage. Practical applications Ultraviolet (UV‐C) radiation is widely used in food disinfection. This technology is free of residues, low‐cost, and easy‐to‐use, but still little used in grain postharvest. Inhibition of weevil population growth is observed when UV‐C radiation is applied to maize containing adult stages of the weevil. In addition, minor changes in maize quality are verified. The knowledge generated by this work can be used by industries and suppliers as an alternative to conventional pest controls.

“…Radiation technique is one of the alternative control methods for stored product pests Azizoglu et al, 2010;Hallman, 2013). For many years, UV radiation has been recognized as a potential stress for organisms and is known to have a wide range of hazardous effects (Mora et al, 2000).…”

SummaryExposure to ultraviolet (UV) radiation is hazardous for all organisms. UV shows numerous effects on insects. In this study, mortality effect of UV on Ephestia kuehniella Zeller, 1879 (Lepidoptera: Pyralidae) larvae was studied. The larvae were exposed to UV radiation (254 and 365 nm) at different time periods (15, 30, 45 and 60 min). After exposure, mortality rate, comet assay studies, antioxidant enzyme activities (SOD, CAT, GST and GPx), and MDA levels were investigated on the larvae. The mortality rate of E. kuehniella larvae increased with increasing exposure times. It was determined that 254 nm was more effective than 365 nm compared to the effects of short (254 nm) and long-wave (365 nm) radiations on mortality rate of E. kuehniella larvae. Likewise mortality rate, 254 nm had more potency than 365 nm on antioxidant enzyme activities and levels of MDA. According to the comet assay results, the tail DNA% and comet tail length significantly increased in all exposure times at 254 nm, but these changes were seen only 45 min and 60 min at 365 nm of UV radiation. Therefore, tail DNA% and tail lenghts of 254 nm radiation could be greater than the tail lenghts of 365 nm UV radiation. As a result, the UV radiation could be effectively as a safe pest control method and as an alternative to environmentally hazardous chemical pesticides. Key words: Ephestia kuehniella, UV radiation, mortality, antioxidant enzymes, comet assay ÖzetUltraviyole (UV) radyasyona maruz kalmak tüm canlılar için tehlikelidir. UV böcekler üzerinde birçok etki göstermektedir. Bu çalışmada, Ephestia kuehniella 1879 (Lepidoptera: Pyralidae) larvaları üzerine UV'nin öldürücü etkisi çalışıldı. Larvalar UV radyasyonuna (254 ve 365 nm) farklı zaman peryotlarında (15, 30, 45 ve 60 dk.) maruz bırakıldı. Çalışma sonunda larvaların ölüm oranları, komet değeleri ve antioksidan enzim aktiviteleri (SOD, CAT, GST ve GPx) ve MDA seviyeleri araştırıldı. Işınlama süresi arttıkça E. kuehniella larvalarının ölüm oranları artmıştır. Kısa (254 nm) ve uzun (365 nm) dalga boylarını ölüm oranları üzerindeki etkilerini karşılaştırdığımızda 254 nm dalga boyunun 365 nm dalga boyundan daha etkili olduğu belirlenmiştir. Bu durum, ölüm oranı, antioksidan enzim aktivitesi ve MDA seviyesinde de tespit edilmiştir. Komet değerlendirme sonuçlarına göre kuyruk % DNA'sı ve komet kuyruk uzunluğu 254 nm dalga boyutunun tüm uygulama zamanlarında istatistiksel olarak artarken bu değişimler 365 nm UV radyasyonun yalnızca 45. ve 60. dk. larında tespit edilmiştir. Bundan dolayı, kuyruk % DNA'sı ve kuyruk uzunluğu 254 nm dalga boyunda 365 nm dalga boyuna göre daha fazladır. Sonuç olarak, UV radyasyon depo zararlılarının kontrolünde güvenilir bir metod ve çevreye zararlı kimyasal pestisitlere bir alternatif olarak kullanılabilir.Anahtar sözcükler: Ephestia kuehniella, UV radyasyon, ölüm oranı, antioksidan enzimler, komet değerlendirme
