“…Through out the year Ultra violet index is high, during summer UV index is 9-11, during winter UVI is 3-6, and even higher during a clear sky day in monsoon season. 9 In our study, female and younger age offi cer groups well aware on the practice of skin care. Several studies found that the younger generation is more insistent in taking protective behaviour compared to the older generation while the studies done by Campbell (1994) 10 and Kristjansson (2004) 11 showed opposite results.…”

Background: Police officer serves a vital role in maintaining safety and serve are role model for discipline throughout the world, they are non–intentional type sun exposure(NISE).The objective of our present study was to evaluate photo protector practice, knowledge in response to Ultra violet Radiation ,Sunscreens and sun related photodermatosis. Methodology: A cross sectional study was conducted in traffic police officer at different locations at Kathmandu. Data was collected by using self-administered questionnaires and interviewed by Dermatologist to establish their knowledge and behaviour and practice in relation to ultra violet radiation and photo-protection. Result: Out of 265 participants, mean age was 27.1 years. Respondent with graduation and master degrees had knowledge and practice toward UVR, follow by higher secondary education. Regarding the practice for photo protection only 59.6% had knowledge about sunscreen, 39.6% knowledge about Ultraviolet Radiation and 24.9% had knowledge about Ultra Violet Index .Skin problem like melasma, premature wrinkles, and hardening of skin, polymorphic light eruption, burning foot syndrome, dermatophytes, and varicose vein. Conclusion: Traffic police officers showed good practices in term of wearing hat, clothes that cover most of the body parts but poor practice over sunscreen, UVR, UVI. Lectures & seminar regarding the awareness and photo protection practice should be recommended. With lack of awareness among police officers and providing sunscreen for free should be considered by Police authorities. Similarly lectures & seminar on sun protection should be provided in regularly.

“…Along with the pest, the incidence of huanglongbing has also been found to decline with altitude [ 35 , 82 , 83 ]. The Himalayan region is characterised as an area that receives high amounts of UV radiation [ 84 , 85 , 86 , 87 , 88 , 89 ], and the absence of D. citri at the higher altitudes found in the study by Om et al [ 35 ] may be due to amounts passing a critical dose sufficient to either directly affect the insect or through indirect effects on its host plants or microbiome. ‘ Candidatus Carsonella ruddii’, the primary endosymbiont of psyllids [ 90 , 91 ], lacks the ability to repair damaged DNA [ 92 ], which may render it susceptible to UV radiation.…”

Populations of Diaphorina citri decline with elevation and, in a study in Bhutan, were rarely found above 1200 m ASL. The impact of ultraviolet (UV) radiation, particularly UV-B, on immature stages of the psyllid was proposed as limiting factor. As no studies have been undertaken on the influences of UV radiation on the development of D. citri, we examined the effects of UV-A and UV-B on different stadia of the psyllid. In addition, compliance with the Bunsen–Roscoe reciprocity law was examined. Irradiation with UV-A marginally reduced egg hatch and the survival times of emerging nymphs. Early instar nymphs were little affected by this waveband, but the survival of adults was reduced at the higher doses used. With UV-B, egg hatch and the survival times of early and late instar nymphs declined in proportion to UV-B dose. A dose of 57.6 kJ m−2 d−1 reduced the survival time of only adult females. Female fecundity was reduced at high UV-A and UV-B doses but increased at low doses. The Bunsen–Roscoe law held true for eggs and early instar nymphs for different durations and irradiances of UV-B. Eggs and nymphs had ED50 values for UV-B lower than the daily fluxes of this wavelength experienced worldwide. Thus, UV-B could be a factor causing the psyllid to be scarce at high elevations.
