Background Fruit flies are important insect pests of horticultural crops. Pesticides used to control them which cause environmental and health hazards; therefore, other alternative sustainable management measures are required. Main body Successful implementation of an integrated pest management program, using biological control agents, needs synchronization of parasitoids with hosts selection and exposure time. The present study was conducted to assess the biological activity of the parasitoid species, Dirhinus giffardii (Silvestri) (Hymenoptera: Chalcididae), against the melon fruit fly, Zeugodacus cucurbitae (Coquillett), and the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), at different exposure durations (24, 48, and 72 h). The experiments were conducted under standard laboratory conditions. Significant differences in the parasitism rate of D. giffardii were observed for both species at different exposure durations. The maximum parasitism rate of D. giffardii (52.60 ± 2.84%) and (42.73 ± 2.74%) was observed at 48-h exposure period for Z. cucurbitae and B. dorsalis, respectively. Also, a comparison between both species showed a difference in parasitism rate at 24 and 48 h and a positive correlation between percent parasitism and exposure duration. Adult emergence of D. giffardii showed a maximum emergence rate from pupae of Z. cucurbitae (63.55 ± 4.02%) and B. dorsalis (51.61 ± 2.33%) at 10 days interval, respectively. However, the daily emergence of the parasitoid was not correlated to exposure duration in both species. The results of the present study may serve in the mass rearing of D. giffardii. Conclusion The biological activity of D. giffardii was maximum at 48 h of exposure for both fruit fly species, and this important information may improve the mass rearing technology of D. giffardii.

Irritable bowel syndrome (IBS) is a gastrointestinal disease of intestinal mobility. IBS present with variable clinical symptoms making the treatment difficult. IBS is quiet prevalent around the globe with different frequency. Differences in frequency and gender is due to diet habit. It is less frequent where diary product and vegetable are frequently consumed as compared to those who consumed meat. Lactobacillus plantarum 299v (L. plantarum 299v) is the most widely studied strain in the IBS patients. It is resistant to the actions of intestinal acids and bile, colonizes the human colonic mucosa and is non-pathogenic in nature. The efficacy of Lactobacillus plantarum 299v L is different in different study. The present study was designed to find the efficacy of Lactobacillus plantarum 299v in comparison to placebo in randomized control trial.

The efficacy of Lactobacillus plantarum 299v L is different in different study. The present study was designed to find the efficacy of Lactobacillus plantarum 299v in comparison to placebo in randomized control trial. MethodOne hundred and ninety patients were assessed for eligibility 46 among them were excluded from the study and twenty four declined to participate in the study. One hundred and twenty patient of IBS was grouped in two different groups. The one was treated with Lactobacillus plantarum 299v and the other was treated with placebo. Symptoms of IBS, like abdominal pain, bloating and complete rectal emptying was noted and interpreted among the groups. Results There was no statistically significant difference in relieving abdominal pain, bloating, rectal emptying in Lactobacillus plantarum 299v treated group and placebo treated group. Conclusion This randomized control trail of Lactobacillus plantarum 299v fail to show signicant efficacy in IBS treatment as compared to placebo.
