“…As an ecosystem component, Duttaphrynus melanostictus performs predation interactions with various insects because it utilizes biotic components as a source of nutrition and energy. There are several species compositions of prey insects, in contrast to previous findings [14][15]. These facts indicate that (1) this species can utilize more insect species than previously known, (2) high adaptation in utilizing various types of feed resources for survival in various types of habitats, and (3) natural food of Duttaphrynus melanostictus is predominated by insects, like other amphibian species [32].…”

The house toad (Duttaphrynus melanostictus) is a highly adaptable amphibian species, and is commonly found in urban areas. On Lombok Island, this species has the highest abundance in non-forest habitat types. In their habit, amphibians function as predators of various types of insects and various types of invertebrates. There are several research reports on prey items from Duttaphrynus melanostictus, but information regarding its role as control of harmful insects is still limited, especially on the island of Lombok. On the other hand, science learning aims to introduce the surrounding environment to students. Therefore, integrating the roles of species commonly found in these settlements is a necessity. The purpose of this study was to analyze the potential of Duttaphrynus melanostictus as a pest control insect, and its urgency in science learning, especially in elementary schools. The study was conducted using gastric surgery analysis method. The frog's stomach was taken continuously until the data was saturated, i.e. the data obtained were the same as the previous surgeries. The results showed that Duttaphrynus melanostictus preyed on 14 types of insects. There are 12 species (85.71%) of which are harmful insects. If classified, 9 species (75%) are insect pests, and 3 species (25%) are disease vectors. Information on the role of this species can be substituted for science lessons in elementary school. The appropriate topics are (1) the importance of balancing and preserving natural resources in the environment, and (2) the relationship between ecosystem components and food webs in the surrounding environment.

“…In Sumatera, red chilies are widely cultivated in Lampung, Jambi, Bengkulu, West Sumatera, North Sumatera, Aceh, and South Sumatera. Consequently, numerous researchers are studying red chili (Iskandar & Ayu, 2021;Jasmin et al, 2020;Jhon et al, 2018;Nasution et al, 2021;Pakpahan & Nababan, 2018). South Sumatera chili is extensively grown in both highlands and lowlands (Annissa & Impron, 2017;Ganefianti et al, 2017).…”

Chili is one of the important commodities in Indonesia. Chili cultivation faces many obstacles, leading to a decrease in production, such as virus infections. Yellow leaf curl and curly top viruses are groups of viruses that are often found in chili fields. This research was conducted to investigate the effect of intercropping (basil-chili) in suppressing viral diseases, especially yellow leaf curl and curly top viruses. A Randomized block design was used for this research, including intercropping and monoculture. The parameters observed in this study included disease incidence and intensity, the number and weight of chilies. Symptoms of virus infection include leaf curl, yellowing, and stunting. The disease has been reported to be transmitted by insect vectors, such as Aphis gossypii and Bemisia tabaci. The results showed that the incidence and intensity of yellow leaf curl and curly top virus diseases in chili pepper and basil plants were not significantly different in each treatment. The number of healthy chilies and their weight were also not significantly different. Damaged chilies are fruits that have been attacked by fruit flies. Basil intercropped with chilies attracts fruit flies, which affects the quantity and weight of the harvested chilies. The population of B. tabaci was significantly different in each treatment, while A. gossypii did not show significant differences among the treatments. Intercropping basil and chili increased the population of A. gossypii, while the population of B. tabaci decreased in this treatment. These two insect pests are vectors for yellow leaf curl and curly top viruses.
