Abstract

The purpose of this study was to analyze the diversity of weed species in corn plantings in the Usaha Maju Farmer Group, Naibonat Village, East Kupang District, Kupang Regency which took place from July to December 2020. Observation of weeds was carried out using the quadratic method. Observations in the sample plots by making observation subunits measuring 1 x 1 m2. Unknown weed species were collected and then identified using the Plant Snap application and making a herbarium. The results showed that there were 13 weed species found associated with corn plants, namely Eleusine indica, Setaria pumila, Echinochloa colona, Cynodon dactylon, Digitaria ciliaris, Xanthium strumarium, Centela asiatica Ipomoea obscura, Euphorbia hirta, Tridax procumbens, Spigelia anthelmia, Passiflora foetida, and Phyllanthus niruri. Based on vegetation analysis, Eleusine indica and Euphorbia hirta were more dominant than other weed species with absolute densities of 20.5m2 and 21.3m2 per maize plant, respectively.

Abstract

This research aims to determine the types of fruit flies that exist in bitter melon cultivation belonging to the Tunas Muda Buraen Farmers Group, Buraen Village, South Amarasi District, Kupang Regency. This research was carried out on land belonging to the Tunas Muda Buraen Farmers Group, Buraen Village, South Amarasi District, Kupang Regency and the Plant Pest Laboratory, Faculty of Agriculture, Nusa Cendana University in August-November 2024. The fruit flies obtained from the traps were Bactrocera dorsali, Bactrocera papayae, and Bactrocera carambolae. However, the species obtained from rearing is the Bactrocera cucurbitae species, this species is a different species from the existing trap results. The different results are thought to be because the species obtained had different hosts, or the main host was not the bitter melon plant. The second factor is because the rearing activity does not use all the fruit that is attacked, thus giving the possibility that the unused fruit has been attacked by fruit flies, and the last factor is because the traps have been set early so there is little chance for other species to attack the bitter melon plants. From these factors, it is proven that the B. cucurbitae species damages bitter melon plants with the intensity of damage to bitter melon fruit being expressed as light damage intensity with an assessment of 6.21%.

Abstract

This research was conducted in Lakekun Village, Kobalima District, Malaka Regency from May to July 2023, aiming to determine the types of insect pests and natural enemies in mung beans. Data collection was carried out using direct observation techniques on mung bean plants and sampling using several traps. The types of traps used were pitfall trap, swepnet, yellow sticky trap, swing net and light trap. Sampling was done diagonally to determine the sample unit. The number of observation plots in the field is 3 observation plots. in 1 plot there are 5 sample units and a total of 3 observation plots there are 15 aub plots observed. Insect pests found on mung bean in the research location have three roles, namely as pests, predators and parasitoids. Species that act as pests consist of Artherigona exigua, Nezara viridula L, Aphis craccivora, Halyomopha halys, Riptortus linearis, Adoretus sp. and Gralliclava horrens. Insects that act as predators consist of Menochilus sexmaculatus, Coccinella transversalis, Orthhetrum sabina, Iscunara senegalensis. While insects that act as parasitoids are Tiphia femorata. The highest population found at the research site was Aphis craccivora which amounted to 315 individuals and the lowest population was Graliclava horrens with a total of 7 individuals. The value of the diversity index in mung bean plants is classified as moderate, namely 1.89. Keywords: diversity, insects, mung bean, identification.
