Abstract

Biology and Transformation of the Migratory Locust Locusta migratoria manilensis Meyen (Orthoptera: Acrididae) at Several Laboratory Population Density Levels. The migratory locust, Locusta migratoria manilensis Meyen (Orthoptera: Acrididae) is one of insect pests in Indonesia that undergoes a unique polymorphic biology. The locust develops a transformation phase which is triggered mainly by high population density. Its recent outbreaks in several regions of Indonesia cause major concern and control strategies must be developed to strengthen control efforts in the future. Its unique polymorphic phenomenon, therefore, must be investigated thoroughly for the basis of management of the outbreak. Due to its agility and its long range flying ability, the most realistic technique to study behavioral and morphological change of the locust is in controlled condition at a laboratory or a green house facility. The experiment was aimed to study effects of colony densities on the biology and transformation process of the migratory locust. More specifically, the experiment was to study effects of population density on the feeding activity, mortality rate, and the ratio of F/C and E/F of the migratory locust L. migratoria manilensis. The population densities were simulated in colonies at 2, 5, 10, 20, dan 30 couples per cage (cage size: 45x45x90 cm) reared in a green house. Results of the experiment show that, in general, higher densities of the migratory locust colonies tended to feed more rigorously than those of the less dense colonies. The locust remained in solitary phase at the density of 2-5 couples per cage whereas the transient phase occured at the density of 10-20 couples per cage. The colonies transformed to gregarious stage when their densities were 30 couples per cage or higher. Mortality percentage tended to be higher at colonies with higher density, especially for the third instar of the migratory locust.

Abstract

Several experiments have been conducted to study genetic variation, fitness and reproductive incompatibility of H. varicornis from different geographic populations. Genetic variation from Pandai Sikek (PS), Alahan Panjang (AP) and Kayu Aro (KA) was analyzed by using random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) technique and the similarity of genetics measured using NTSys program. The fitness of female wasps such as longevity, fecundity and preoviposition was observed and then compared among those populations. Incompatibility in reproduction was determined by accounting of reproductive compatibility (RC) index in crossing of intra and interpopulation both of PS and AP. The results showed high genetic variation of H. varicornis among population from Alahan Panjang, Pandai Sikek and Kayu Aro with similarity coefficient of 30 to 70%. The best fitness showed the female wasps from Kayu Aro that was significantly different (P= 0.00) in longevity (24.60 ± 6.4 days), fecundity (63.6 ± 28.6 eggs) and parasitization (53.60%) but not significantly different (P=0.07) in number of the first day eggs (1.1 ± 1.4 eggs). Crossing of AP and PS indicated incompatibility in reproduction among the population.

Abstract

The effect of Aglaia odorata Lour. twig extract on development of a parasitic wasp Eriborus argenteopilosus (Cameron) in its host Crocidolomia binotalis Zeller. This laboratory study was conducted to evaluate the effect of ethyl acetate soluble fraction of methanolic twig extract of Aglaia odorata Lour. (Meliaceae) on the development of a parasitic wasp Eriborus argenteopilosus (Cameron) (Hymenoptera: Ichneumonidae) in its host larvae Crocidolomia binotalis Zeller (Lepidoptera: Pyralidae). Extract treatment was given through the host. C. binotalis larvae were fed broccoli leaves treated with A. odorata extract at LC25, LC50, and LC70, then were exposed to the female adults E. argenteopilosus. Mortality of the parasitized host larvae, survival of immature stages of the parasitoid in the host larvae, and longevity and fecundity of the emerging female parasitoids were recorded. The results showed that combinations of extract treatments (at LC25, LC50, and LC70) and parasitization increased the mortality of the parasitized host larvae (38,4 - 42,7%) more than twice that of the parasitized control larvae. Those extract treatments, however, did not exert any negative effects on developmental time of the parasitoid immature stages nor on some morphological characters, longevity and fecundity of the emerging female parasitoids. Thus, A. odorata extract showed promise to be integrated with the parasitoid for the control of C. binotalis.

Abstract

Eggs of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) on its host plants could beparasitized by some species of parasitoids, especially of the genus Trichogrammatoidea andTrichogramma. This research was aimed to study the population dynamics of egg parasitoids of H.armigera on unsprayed fields of cotton monoculture and intercropped with maize. The plot size ofeach field was 19 m x 20 m, with five replicates. We collected H. armigera eggs from both fieldsperiodically since 23 days after planting (dap) to 100 dap. The eggs were collected on 9 sample units(size of sample unit: 1 m2) in 7-days interval. The number of collected and parasitized eggs wasrecorded and the emerged parasitoids were identified to species level. The result showed that thefluctuation pattern of H. armigera egg population was not different on cotton monoculture and cottonintercropped with maize. The parasitoid population was relatively high during the flowering phase ofcotton and maize. The parasitoids of H. armigera eggs found in cotton monoculture and cottonintercropped with maize were T’toidea armigera, T’toidea guamensis, T’toidea bactrae bactrae,T’toidea bactrae fumata, T. chilonis and T. chilotraeae . The dominant species on early season untilthe flowering phase of the plants was T’toidea armigera, while on the latter phase of the plantphenology was T. chilotraeae. Implication of this population dynamics and the succession of theparasitoids in biological control are discussed.

Abstract

Presence of insects in agricultural habitat is affected by the surrounding circumstances such as the complexity and structure of landscape. Landscape structure is often formed as a consequence of the fragmentation of semi-natural habitat, which can negatively affect species richness and abundance of insects. This study was aimed to study the effect of complexity and structure of landscape on the diversity, abundance and traits of flower-visiting insects in cucumber fields. This study was conducted in cucumber fields surrounded by other agricultural crops, shrubs, semi-natural habitat and housing area, in Bogor, Cianjur and Sukabumi regencies, West Java, Indonesia. In a total of 16 agricultural areas, complexity and parameter of landscape especially class area (CA), number of patches (NumP), mean patch size (MPS), total edge (TE), and mean shape index (MSI) of seminatural habitats were measured. Sampling of flower-visiting insects was conducted using scan sampling methods. The result showed that landscape complexity affected species richness (but not abundance and trait) of flower-visiting insects both for mobile and less-mobile insects. Flower-visiting insects also responded differently to landscape structure. Species richness, abundance and variation of body size of mobile insects were affected by structure of semi-natural habitat.

Abstract

Wolbachia that have been found to be maternally inherited in arthropods, including insects behave primarily as a reproductive parasite by inducing feminization and/or death among genetic males; causing cytoplasmic incompatibility, and activating parthenogenesis, in host insects. This research aims to detect the presence of Wolbachia in several parasitic insects and to determine the diversity of Wolbachia at the supergroup level. Insect genetic samples were collected, amplified using wsp (Wolbachia surface protein) gene and with the sequences then analyzed using species homologues drawn from the Genbank database. These activities were dedicated to detect intracellular presence of Wolbachia and assembled the phylogenetic tree of the respected bacteria. Phylogenetic analysis confirmed that Wolbachia existed in the samples belonged to the supergroup A (found in Cherapron sp.) and supergroup B (found in E. japonica). Wolbachia were detected in seven out of nine wasps i.e. Anagyrus lopezi, Ceraphron sp., Microplitis manilae, Brachymeria lasus, Scelionidae sp01, Trichogramma sp, and Exorista japonica. Single infection by Wolbachia supergroup A was detected in A. lopezi, Ceraphron sp., M. manilae, and Scelionidae sp01. Meanwhile single infection by Wolbachia supergroup B was detected only in E. japonica. Double infection by both supergroups occurred in B. lasus and Trichogramma sp. samples.

Abstract

Endophytic fungi is an endosymbiont that lives within host plant tissues and does not necessary cause any harm to plants. This type of fungus are important as mediators in plant-herbivore interactions. One of the endophytic fungi in rice is Nigrospora sp. The effects of Nigrospora sp. on the biology and demographic statistic of Nilaparvata lugens Stál (Hemiptera: Delphacidae) were studied in the laboratory. We used Nigrospora sp. culture powder was used to inoculate the fungi to rice seeds by mixing 10 g of flour endophytic per 1 kg rice seeds. The mixture was then stored in damp and dark storage. Results showed that the rice seeds treated with endophytic fungi showed some resistance to N. lugens. Eggs and early stages of nymph mortality was increased, higher than the control. Endophytic fungi also affect the nymphs growth rates by slowing it down, prolonging N. lugens life cycle, preoviposition period as well as delayed the age at first reproduction. N. lugens population growth is effected by Nigrospora sp. in laboratory scale. Thus, it has the potential as an alternative way to control N. lugens population. In addition, inoculation of endophytic fungi could be a useful method for protecting rice plants from N. lugens.

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

The condition of agroecosystem may affect the diversity and effectiveness of parasitoid communities as natural enemies of insect pests. Agricultural intensification such as monoculture cultivation as well as application of insecticide could also cause declining to parasitoid diversity and ineffective performance of parasitoids in agricultural field. The objective of this research was to study trophic interaction between pests and parasitoids in different field of vegetable crops and to investigate the factors that determining those interactions as well as its implication on parasitoid effectiveness. Vegetable crop fields were grouped into three different categories i.e. based on the pattern of cultivation, diversity of vegetable crops around the field and age of plant. On each crop field, insects were sampled using 50 m of transect by collecting eggs, larvae and pupae of pests. In total, 15 species of pests and 15 species of parasitoids were recorded from eight species of vegetable crops. Based on the analysis, trophic interaction between pests and parasitoids were affected by cultivation system, condition of crop field (species diversity of crops in its surrounding) and age of vegetable plants. Although it was not significance, the effectiveness of parasitoids according to their parasitism level, tend to higher in trophic interaction that determined from crop field with organic systems and with diverse of crop plants.
