Abstract

The edible amaranth (Amaranthus tricolor L.) is an important vegetable growing around the world. The famous vegetable plant is known for two types: green and green-red amaranth. The purpose of the research is to study an abundance of beneficial arthropods in the edible amaranth ecosystem using pitfall trap. The study was conducted in the edible amaranth farmers plantation at Kanreapia Village, Gowa Regency, South Sulawesi in the wet season from August to December 2022. The pitfall trap was embedded into the ground at the same depth as the soil surface for 24 hours. The position of a pitfall trap in the center and every corner of the plot. The pitfall used five pieces for every plot (total 20 pitfall). The result showed important predator arthropods collected from pitfall traps were divided into two groups: spiders and insects. In this research, the beneficial arthropods are found in similar habitats in the edible amaranth. The highest percentage was Gryllidae such as Gryllus sp. (54.83%). The spiders group from Lycosidae, Lycosa pseudoannulata (25.80%) and from Oxyopidae, Oxyopus sp. (19.35%). The pitfall trap showed the percentage number of Valanga sp. (Acrididae) about 36%.

Abstract

The common problem in insect artificial diet for Lepidopteran, especially Troides helena (Linnaeus) (Lepidoptera: Papilionidae) larvae is preparing wheat germ to cover the nutritional needs of the insect target. All of the material formulated in the artificial diet has different textures, water content, and nutritional composition compared to the natural diet from the butterflies host plant, Aristolochia leaves. The ability to choose and control the nutritional component of the artificial diet gives the best results for the mass-rearing of insect targets. Larvae of T. helena have been successfully mass-reared in artificial diet-based red beans as a substitute for wheat germ. Artificial diet incorporating red beans or kidney beans have been shown to increase longevity and the successful emergence of the adults from the pupal stage. An artificial diet was given to T. helena larvae from the 2nd instar until they formed a pupal. Previous research showed that T. helena adults, while hatching normally a males, often remained crippling butterflies. In the future, the artificial diet of butterflies is the solution increasing population of insects in Bantimurung-Bulusaraung National Park, South Sulawesi.
