“…It was demonstrated that ULV was effective in reducing development in different storage insect pests (Collins and Kitchingman, 2010). This could be possible due to the fact that the UV radiation reduced hatching of eggs and adult eclosion which gets support from the findings of Faruki et al (2007).…”

The adults of Tribolium castaneum were exposed to ultraviolet (UV) light (254 nm) for different time periods (2, 4, 6, 8, 10, 12, 14, and 16 min) and each replicated thrice. The culture of unexposed beetles was maintained for comparison. The different time period levels were maintained in the laminar flow cabinet using ultra-violet radiations (254 nm). The fecundity (113.00 eggs/female), hatchability (55.33%), pupation (53.01%) and adult emergence (F 1 ) (36.67) were maximum in unexposed beetles, whereas, minimum in beetles exposed for 16 min (23.50 eggs/ female, 29.33, 24.98 and 4.00%, respectively) under UV radiation.

“…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, ). UV radiation can be divided into three ranges: UV‐A (320–400 nm), UV‐B (280–320 nm), and UV‐C (200–280 nm), with high disinfecting power and germicidal action, and is widely used in water treatment (Hollósy, ).…”

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.

“…At the same time, damaged embryo had helped the Trichogrammatid for successful parasitization. Faruki et al (2007) also observed decrease in egg hatching and adult emergence in UV radiated eggs of Tribolium castaneum, T. confusum and the almond moth, Cadra cautella. Herlin et al (2015) had also observed effect of UV radiation on the life cycle of rice moth Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae) and disruption in hatchability.…”

Mass rearing of numerous biological control agents depends on large amounts of eggs of factitious hosts like rice meal moth, Corcyra cephalonica (Stainton) (Lepidoptera : Pyralidae). Corcyra eggs sterilization is required before they are used for parasitisation by Trichogrammatids. To meet the requirement of eggs sterilization of this insect, a new innovative device was invented, fabricated and studied. It consisted of an enclosed structure having semi-circular shaped drawer. An ultra violet (UV) tube of 30 W is fixed on the centre of its ceiling to maintain a uniform distance of 35 cm from the eggs to be sterilized. An exposure of 10 minutes to eggs of C. cephalonica was required to get optimum sterilization. As whole body of the device was an enclosed structure, hence, there was no exposure of UV rays to the laboratory workers. The different sized-models (150,100, 50 of "egg cards" required for Trichogrammatids) can be fabricated to meet the diverse requirements. Irradiated eggs were found having no any adverse effects on the abilities of Trichogrammatids parasitisation and its emergence. It can also used for UV sterilization of laboratory materials like glassware, plastic ware, clothes, cotton etc. The period of exposure to the UV light was set using timer. This innovative UV chamber had numerous advantages i.e., the UV rays used had damaged the host embryo. The damaged embryo could not develop into next stage, at the same time damaged embryo found suitable for parasitization of Trichogrammatids. The whole body of the device was made-up of an enclosed structure; hence, there was no exposure of UV rays to the laboratory workers. The different sized-models (150,100, 50 of "egg cards" required for Trichogrammatids) can be fabricated to meet the diverse requirements of clients. As the UV chamber was made up of metal and ply boards, hence, it was durable. The longitudinal flanges provided in the drawer of the device prevented the host egg bearing cards to glide one over other from curved surface. The device was found safe and effective for sterilization of Corcyra eggs and easy to operate.
