Abstract

This study aims to identify and determine the parasitic level of Bactrocera mcgregori parasitoid from melinjo fruit (Gnetum gnemon) from Tanah Laut district and Banjarbaru Kalimatan Selatan City. The identification results of the three parasitoids showed the characteristics of the Hymenoptera order, the family Braconidae. The three parasitoids are Psytallia flecheri habitus (Silvestri) parasitoid, Psytallia lounsburyi (Silvestri) and Diachasmimorpha longicaudata (Cameron).

Abstract

Dates (Phoenix dactylifera L.) belong to the Arecaceae family of palms. Banjarbaru is one of the areas that started planting date palms in South Kalimantan. The community's knowledge of date pests still lacks. Therefore it becomes a problem for farmers. Before proper control is carried out, it is necessary to understand the types of pests first. Arthropod data on date palms at the Plantation and Livestock Service Office of South Kalimantan Province are not available. Hence, it is necessary to conduct inventory research and arthropod identification. This study aimed to determine the types of arthropods in date palms (P. dactylifera L.) in Banjarbaru. The method used was a survey method with purposive sampling carried out by collecting arthropods using swing nets, yellow sticky traps, and directly from four different locations. The field observations at four locations found 43 types of arthropods totaling 98 individuals. Twenty arthropods act as pests, 13 individuals as pollinators, and 10 individuals as predators. The arthropods were classified into ten orders and 27 families, with the largest number of individuals coming from the Lepidoptera order.

Abstract

Arthropoda Preference Test has been carried out on Zinnia Sp. In paddy plantations (Oryza sativa L.). This study aims to determine the level of arthropod diversity in paddy cultivation areas using Zinnia sp. compared to rice without Zinnia sp. The method used is a survey method with purposive sampling which was determined intentionally. The results of the comparison of the 2 treatments showed that in the vegetative phase the number of pests, predators, and parasitoids was more without treatment than using treatment, while the generative phase used less treatment than without treatment. Indeed, from the number of species obtained, there was no signicant difference, but it was seen from the number of fewer pests and more predators with refugia plantations compared to those without refugia. This is evidenced by the comparison of rice yields obtained more with treatment than without treatment 561:429 in units of kg.

Abstract

This study observed the spacing effect on arthropod diversity in soybean from November 2017 to January 2018. The treatments were arranged in a randomized block design, with five replications and five different spacings: A - 20x20 cm, B - 20x30 cm, C - 20x40 cm, D 20x50 cm, and E - 20x60 cm. The highest arthropods were found at the narrowest spacing (20x 20 cm) and the lowest at the broadest spacing (20x60 cm). Soybean plantations in the study area had a medium category for diversity index (H'), a fairly even category for evenness index (E), and a low category for dominance index (D). All types of relative index values did not differ between treatments.
