Abstract

Approximately 80% of flowering plants are highly dependent on insect pollination, including the chili pepper (Capsicum frutescens). Environmental conditions serve as parameters for insects in their activities. Therefore, this study was conducted to determine the diversity and abundance of flower-visiting insects in C. frutescens and their environmental factors. Field observations of flower-visiting insects were conducted during the dry season utilizing aerial capture methods. The data was analyzed using diversity, abundance, evenness, and dominance indices equations. Multiple linear regression analysis was also conducted to determine the abiotic and biotic factors (environmental factors) that influence the abundance of flower-visiting insects. The analysis results showed that a moderate trend in the diversity of insect and as many as 33% of the total recorded insect individuals belong to the Vespidae family. The Allorhynchium argentatum showed the highest species abundance (27% individuals). Based on the multiple regression analysis results, environmental factors had a non-significant native influence on the abundance of flower-visiting insects. Environmental conditions during the dry season have a weak influence on insect interactions with plants.

Abstract

Utricularia vulgaris is one of the aquatic carnivorous plants that is able to grow in low-nutrient environmental conditions. This unique plant is also a macrophytic plant whose entire body except for the flowers is submerged in water. Utricularia vulgaris also has no roots so it grows to float in water. The plant was found growing in an environment polluted by heavy metals. Several studies have shown that U. vulgaris is able to absorb several types of heavy metals effectively, such as Cu, Mn, Zn, and Fe. These heavy metals are needed in small amounts by organisms, but in high amounts they can inhibit the growth of aquatic organisms. Utricularia vulgaris, a carnivorous plant, has shown the potential to absorb heavy metals, making it a subject of interest for phytoremediation.

Abstract

Calotropis gigantea, a wild plant thriving in arid environments, has been traditionally used for medicinal purposes by communities near Baluran National Park (BNP). The latex of C. gigantea is used as a crab poison due to its ability to cause fatal damage and separation of body parts, possibly related to chitin disruption in insects. This study explores the potential insecticidal properties of secondary metabolites in C. gigantea using Prediction of Activity Spectra for Substance (PASS) Online. Out of 68 identified secondary metabolites, six show significant insecticidal potential, namely Profenophos, Ethion, Alpha-Citral, 1-Phenylethyl acetate, (E)-dec-3-en-2-one, and Benzaldehyde. Notably, Profenophos, Ethion, Alpha-Citral, and Benzaldehyde exhibit toxic properties effective against insects, with enzyme inhibitory activity affecting nerve signaling and immune systems, suggesting potential for bio-insecticide development.
