Abstract

The aim of the research was to identify the influences of the number of hosts and the density of parasitoid on the behavior of selfsuperparasitism at Trichogramma chilotraeae. The behavior of selfsuperparasitism was studied by examining the percentage of selfsuperparasitism as affected by the variability of host number (3, 6, 12, 24 and 48) exposed to 1 and 2 female parasitoids. A descriptive analysis was conducted in order to identify an ovipositioning sequence. The results indicated that the number of hosts significantly affected the  selfsuperparasitism percentage in the exposing treatments 1 and 2. The percentage of selfsuperparasitism was positively correlated with the ratio of the host number and the female parasitoid density. The tendency of the selfsuperparasitism behavior occurred in the early stage of ovipositioning.

Abstract

The objective of the research was to study behaviour and parasitism efficiency of the egg parasitoid Trichogramma chilotraeae in relation to host and parasitoid density under laboratory condition. Eggs of Corcyra cephalonica were used as hosts for Trichogramma chilotraeae. Five different host (egg) densities: 3, 6, 12, 24 and 48 eggs were provided to one and two active female parasitoids T. chilotraeae. Percentage of parasitism, female progeny, and selfsuperparasitism were counted. Results showed that, host density was found to have a strong effect on parasitism rate, female progeny and selfsuperparasitism. Two parameters, parasitism and selfsuperparasitism decreases with increasing number of host density, in contrast, female progeny increase with increasing host density. Parasitoid density affected selfsuperparasitism and female progeny only on one level of host density (3 hosts) but not to all parameters of other density treatments.

Abstract

The objective of the research was to study sex ratio and oviposition sequence of egg parasitoid Trichogramma chilotraeae in relation with host density under laboratory condition. Parasitoid response with respect to oviposition sequence was examined by exposing five different host (egg) densities: 3, 6, 12, 24 and 48 on female parasitoids T. chilotraeae. Results showed that in general, female parasitoid laid its female progeny at the beginning of oviposition sequence. Host density was found to have a strong effect on sex ratio. Sex ratio increase with increasing of  host number.

Abstract

Land-use change, mainly from natural forest to agricultural or settlement area, beside have negative impact on biodiversity also cause a new problem such as the presence of pests. In urban area, the most intrusive and common pest is ant. The objective of this research was to study the occurrence pattern of ants in urban habitat. The research was conducted in several urban habitat in of Palu, Central Sulawesi include of settlement, garden, city park, shrub, agricultural area and forest margin. Ants were observed with bait trap using tuna and sugar. In total, we found 38 ant species from all gradients of urban habitat in Palu. Ant diversity were significantly correlated with habitat condition. Species richness and composition of ants tend to increase with decreasing degree of human disturbance (from settlement to forest margin). The most dominant ant that always found in all urban habitat are Anoplolepis gracilipes, Solenopsis geminata and Paratrechina longicornis. Those species are wellknown as tramp species that co-exist with human and have negative impact to local ant species. Urbanization and anthropological disturbance facilitate the occurrence of tramp ant species in Palu urban habitat.

Abstract

One of the common insects that attack tomato plant is whitefly (Bemisiatabaci Genn.). One of those classified as entomopatogen is Verticillium lecanii. The purpose of this study was to determine the effect of V. lecaniispore density on B. tabaci mortality in tomato plants. The study was conducted from January to April 2017 and located in a screening house belonging to the Department of Plant Pest and Disease and Plant Pest and Disease Laboratory, Faculty of Agriculture, Tadulako University. This study used a randomized block design consisting of five treatments including control with three replications so that there are 15 experimental units. The spore density ofV. lecanii consisted of five levels i.e. control (without treatment, p0), 10-3 Spores ml-1 (p1), 10-6 Spores ml-1 (p2),10-9 Spores ml-1(p3) and 10-12 Spores ml-1 (p4). Based on the results of the study, 10-3Spores ml-1 was the spore density that caused the highest mortality of B. tabaci with the mortality of 96.67% within eight days after the application, so the use of V. lecanii was quite effective as a bioinsecticide in controlling imago B. tabaci.
