ABSTRACT
BACKGROUND: Pink bollworm, Pectinophora gossypiella (Lepidoptera: Gelechiidae) is a native pest of Asia and preferably invasion on cotton (Gossypium hirsutum L.) crop as a commendatory host plant. Commercially, G. hirsutum is known as white gold and is an important cash crop all over the globe. Limited studies were published to focus on certain dietary compositions against different cotton pests. Therefore, the present study was undertaken in the laboratory under controlled conditions (temperature: 27 ± 2°C and relative humidity: 60 ± 10%) to determine the impact of three different treatment diets (wheat germ meal, okra, and chickpea) on the biological aspects (lifetime, developmental period) of P. gossypiella. RESULTS: Results revealed that the shortest larval time of P. gossypiella was observed on the okra feed diet while the longest period was recorded on the wheat germ diet. Meanwhile, the pupation delay was noted on the wheat germ diet. The dietary influence was also observed on adult stages of female and male P. gossypiella (43.00 and 37.50 days respectively) and compared with a standard diet (56.50 and 52.50 days respectively). Furthermore, larval weighed more on the okra and chickpea diet followed by the wheat germ diet, whereas highest pupal weight was observed on the standard diet followed by the chickpea diet and okra diet. CONCLUSION: Developmental parameters were significantly variant across all treatment diets, whereas the higher significant difference was reported on the okra diet. Therefore, the existing data of this study offers fruitful interventions for the future as a modified diet for large-scale and rapid mass production of P. gossypiella larvae.

OBJECTIVE: To compare the outcomes of intraoral versus extraoral approach in the treatment of mandibular angle fracture. METHODS: The randomised controlled trail was conducted at the Department of Maxillofacial Surgery, Mayo Hospital, Lahore Pakistan, from September 2016 to March 2017, and comprised patients of mandibular angle fracture who were divided into two equal extraoral group A and intraoral group B. . Baseline and post-operative data on 1st and 7th days as well as 3 months following the surgery was collected. Data was analysed using SPSS 20. RESULTS: Of the 100 patients, there were 50(50%) in each of the two groups. Mean age of group A was 32.28±7.79 years compared to 33.72±8.13 years in group B. There were 39 (78%) males in group A and 36(72%) in group B. The mean pain score at baseline in the groups was not significantly different (p=0.795). On the 7th day and 3 months post-operation, mean pain score was significantly lower in group A (p=0.002). Nerve complication in group A was significantly high compared to group A (p=0.005). CONCLUSIONS: Extra oral approach for the management of mandibular angle fracture is better with regards to pain while intra-oral approach is less associated with nerve complications.
