The study on gut content of Selais Terang Bulan fish (Kryptopterus bicirrhis) in Rantau Kasih village Kampar Kiri river was conducted from Februari- April 2017. The purpose of this study was to know about gut content of Selais Terang Bulan fish which was categorized as main food, supplementary food and additional food. The analysis is done based on the instruction of Natardjan and Jhingran (1961). The gut content was analized using the Index of preponderance.  The result revealed that  the main food of  Selais Terang Bulan fish in Rantau Kasih village is adult Arthropoda with IP value (78.85%), and supplementary food is caterpillar (25.15%). Male and female fishes at have main food of adult Arthropoda with different percentages are (82.81%) male and female (71.32%). Based on the gut content analysis of Selais Terang Bulan fish was a carnivorous fish.

The invasive Drosophila suzukii feeds and reproduces on various cultivated and wild fruits and moves between agricultural and semi-natural habitats. Hedges in agricultural landscapes play a vital role in the population development of D. suzukii, but also harbor a diverse community of natural enemies. We investigated predation by repeatedly exposing cohorts of D. suzukii pupae between June and October in dry and humid hedges at five different locations in Switzerland. We sampled predator communities and analyzed their gut content for the presence of D. suzukii DNA based on the COI marker. On average, 44% of the exposed pupae were predated. Predation was higher in dry than humid hedges, but did not differ significantly between pupae exposed on the ground or on branches and among sampling periods. Earwigs, spiders, and ants were the dominant predators. Predator communities did not vary significantly between hedge types or sampling periods. DNA of D. suzukii was detected in 3.4% of the earwigs, 1.8% of the spiders, and in one predatory bug (1.6%). While the molecular gut content analysis detected only a small proportion of predators that had fed on D. suzukii, overall predation seemed sufficient to reduce D. suzukii populations, in particular in hedges that provide few host fruit resources.
