Abstract

Bintang GP, Andreana D, Yanto J, Marisa A, Ayu DP, Dewi SK. 2022. Efficiency of rangrang ant (Oecophylla Smaragdina Fabrius) as predator of whitefly on chili plants (Capsicum annum L.). In: Herlinda S et al.

Species of pests on cassava plants include mealybugs, red mites and so on. These pests can cause direct damage to plants. This survey aimed to find out several species of pests found in cassava plants and to see firsthand the damage caused by these pests. The method used in this study is a survey method, namely observation (direct observation) on cassava plantations in Tanjung Pering Village, Ogan Ilir Regency, South Sumatra. Based on the results of this survey, the types of pests that attack the cassava plant (Manihot esculante Crantz) are the mealybug species (Phenacoccus manihoti Matile-Ferrero), the urethral pest species (Xylenthropus) and the red mite pest species (Tetranychus Urticae Koch). The mealybugs and red mites attack the leaves, precisely on the back of the leaf bones and for the urethic pests attack the underground roots. So, it can be concluded that there are three pests that attack cassava plants, namely red mites, mealybugs and uret which cause some damage to cassava plants. Preferably, in field surveys it would be better if you document using a macro lens to make it look clearer.

Abstract

Natural controls, such as predators and parasitoids, play a crucial role in maintaining the stability of agricultural ecosystems through biological pest control mechanisms. On the rice agriculture systems, we propose to evaluate the diversity and abundance of natural controls in organic and conventional rice cultivation systems in Tegal Sari Village, Ogan Komering Ulu Timur Regency, South Sumatra. Observations were conducted using a systematic survey method employing various types of insect traps, with organism identification carried out to the level of type. This research is expected to contribute to both academic and practical domains. The results revealed the presence of 10 arthropod species from four orders, including Araneae, with dominant species such as Pardosa pseudoannulata, Tetragnatha extensa, Tetragnatha montana, Tetragnatha sp., Tigrosa annexa, and Zygiella are always higher on the organic rice agricultural system compared to the conventional system. The diversity analysis indicated that sweep nets were more effective in capturing natural controls compared to other traps, with a Shannon-Wiener diversity index value of 2.17, suggesting moderate diversity. These findings emphasize that organic farming supports biodiversity conservation and provides a scientific foundation for the development of pest management strategies.
