Abstract

A study on identication of owering weeds as predatoryinsect alternative foods was conducted at Bantimurung-Bulusaraung National Park, South Sulawesi, Indonesiain February 2013. Among the plants that naturally growin the national park area Cassia siamea andClerodendron paniculatum, which were source of nectarfor insects, particularly butteries. Visits of predatoryinsect to owering weeds and species of both insectsand owering weeds were recorded. The preferredowering weeds visited by the predatory insects are C.striata (Papilionaceae), A.conyzoides (Asteraceae) andL. camara (Verbenaceae) followed by S. nodiflora(Asteraceae), S. rhombifolia (Malvaceae) and L.crustacea (Scrophulariaceae). A large number of adultsand pupae of Coccinella sp. was found in theBantimurung-Bulusaraung National Park.Keywords : nectar, pollen, alternative host, weeds,Indonesia

Abstract

White stem borer Scirpophaga innotata Walkers is known as a species that always causes loss of rice yields in Indonesia and the Asia region and Australia. White stem borer attacks all stages of rice plant growth starting in the nursery until harvest. Until now, synthetic chemical pesticides are still a mainstay of farmers in controlling these pests. Then it is necessary to promote biological pest management, the use of biological agents is pest management technology because a save, economical and effective. Biological control through multiplication and parasitoid release needs to be focused on parasitoid it has adapted to the local environment. This study aims to examine the role of egg parasitoid S. innotata through the type and level of egg parasitization at various phases of rice plant growth. This research was conducted by collecting as many white rice stem borer eggs as possible based on the growth phase of rice plants, i.e. age 11-25 days after planting (DAP), 26-40 DAP, 41-55 DAP, 56-70 DAP, and 71-85 DAP. Observations were made by counting hatching and non-hatching eggs, as well as the type and number of parasitoids that appeared. The results show that the egg parasitoid found was Trichogramma japonicum Ashmead, Tetrastichus schoenobii Ferriere, Telenomus rowani Gahan. The highest level of egg parasitization is at 71-85 DAP.

Abstract

Canopy Arthropod Community Dwellers in Maize Planting. Dwellers the canopy arthropod community structure observed in maize planting in the Village Bajeng, District of North Polombangkeng, Takalar District, South Sulawesi. Observation of the canopy arthropod dwellers performed using suction machine. The results showed that the arthropod community on corn cropping consists of arthropod natural enemies, fitofag and other arthropods. Most of the arthropods that act as predators, which consists of four insect family is Formicidae, Coccinellidae, Carabidae, Gryllidae, and the two spider families is Lycosidae and Linyphiidae. Maize crop canopy arthropod dwellers generally is formicid, coccinellid, cicadellid, and pentatomid. In the maize crop canopy, formicid and aphid abundance were higher in the edge plots, whereas coccinellid, lycosid, and linyphiid higher in the center of the plot.

Abstract

Agriculture cultivation systems and farmer’s income are the crucial issues in many agriculture-based developing countries. Our previous study proved that the polyculture system positively affects land productivity and land-use efficiency. This research investigated the relationship between intercropping farming systems and farmer’s income. We hypothesized that the intercropping farming system increases farmer’s income compared to monoculture. The farming income analysis was carried out using Microsoft Excel and STATA software. The results showed that the farmer’s income derived from the intercropping farming system differs from monoculture. Based on the T-test, the intercropping farming system provided a higher income. Intercropping farming systems that have higher plant diversity, contributed to higher farmer income from different plant yields. Farmers that applied the intercropping system would harvest of 2-3 different plants from one cultivated land at the same time with regular planting distance. These indicated that the intercropping farming system reduces the risk of loss due to price fluctuations of products and the higher input costs during the production process.

Abstract

Intercropping cropping patterns can increase the diversity and abundance of soil arthropods that can function as pest control for plants while maximizing land use. This study aims to determine the diversity and abundance of soil arthropods in the planting of monoculture chilies, intercropping with watermelon, chili intercropping with corn, and chili intercropping with corn and watermelon. The study was conducted in the Maros Regency, South Sulawesi Province, Indonesia. The study was conducted from August to November 2018. A sampling of natural enemy insects using pitfall traps installed for 1x24 hours with observational intervals every two weeks. From all of the cropping patterns, the soil arthropods that were found were spiders and several ant, namely: Odontomachus sp., Monomarium sp. and Anoplolepis sp. The insect diversity index was found to be low with an average of 0.07 in the chili cropping pattern intercropped with watermelon up to 0.17 in the monoculture chili cropping pattern and the chili cropping pattern intercropped with corn and watermelon. Soil arthropods that dominate in all types of cropping patterns were the Minimu monomorium ant species with the highest population of 2,987 individuals found in the chili cropping pattern intercropped with watermelons.
