Abstract

Brown planthopper (Nilaparvata lugens (Stål)) is one of the major rice insect pests that is known to cause high loss of rice production. One of the strategies to control this pest is by using resistant rice varieties. The aim of this research was to study the resistance of IPB 3S variety to BPH by measuring BPH fecundity, sex ratio, feeding activity as well as population increase compared to Ciherang variety against brown planthopper (N. lugens). Fecundity test used a pair of BPH adult infested on 21 days after planting (DAP) of rice plants. Eggs laid in rice stalks and the rest of eggs in the ovary were counted. In order to know the change of sex ratio, a pair of BPH adults was infested on 30 DAP rice plants and allowed to lay eggs. The calculation of sex ratio was conducted at adult stage of BPH by segregation between male and female adults. Feeding activity of BPH was evaluated using ninhydrin and analyzed qualitatively using spectrophotometer. Ten fourth instar nymphs of BPH was infested on 30 DAP old of rice seedlings. Honeydew secreted by BPH was collected to filter paper sprayed with ninhydrin. Population increased test was conducted by infesting five pairs of BPH adults on 35 DAP old rice plants. Observations was conducted on nymph and adult stages. Each test was replicated 10 times. In general, IPB 3S is slightly resistant to BPH, compared to Ciherang variety. The feeding activity of BPH is higher in Ciherang compared to IPB3S. However, the fecundity and population increased of BPH in Ciherang is similar to IPB3S.

Abstract

Rhinoceros beetle (Oryctes rhinoceros) is the main pest of various crops, especially Arecaceae. This research aims to obtain the best growing media of the Arecaceae for the growth of O. rhinoceros larvae. This research expected was designed using a complete randomized design with 5 treatments and 4 replications. The treatment used was different media growth from Arecaceae plants namely palm oil, coconut, sago, and areca, chopped stem, as well as topsoil as control. Parameters measured included individual weight gain of larvae, larval length, a width of O. rhinoceros larvae, with supporting data of soil temperature and humidity, and chemical analysis of organic matter (C-Organic, total N, P-total, and K-Total). The results of the study showed that the growing media of oil palm stem chopped tends to be the most suitable for the growth of O. rhinoceros larvae in case of individual weight increased of larvae (8,8 ± 0,38 g), the length size of larvae (6,15 ± 0,82 cm), and the body width of larvae (1,05 ± 1 cm), and followed by the less and less suitable of the following media growing from chopped stem: coconut, sago, and areca. Thus, oil palms supports the growth of O. rhinoceros more than coconut. This information is important for pest management in smallholders oil palm plantation where oil palms are usually planted along with coconut plants.

Abstract

Pests are one of the main obstacles in improving mungbean production in Indonesia. Currently, conventional control by using synthetic pesticides is less successful because the population and damage due to the organism are still high. This study aims to evaluate the mungbean pest control technology by using biopesticide. The experiment was conducted using randomized block design, five treatments and five replicates. The treatments were P1: preventive of neem seed powder (NSP), entompothogenic virus which contain Spodoptera litura nuclear polyhedrosis virus (Virgra), and conidia of entomopathogenic fungi Beauveria bassiana (BeBas) application; P2: SBM, Virgra, and BeBas application based on economic threshold (ET); P3: application of synthetic pesticides based on schedule; P4: application of synthetic pesticides based on ET; and P5: without control. The results showed that the pests were armyworm (Spodoptera litura (Fabricius)), whitefly (Bemisia tabaci (Gennadius)), Empoasca sp., Megalurothrips usitatus (Bagnall), brown stink bug (Riptortus linearis (Fabricius)), green stink bug (Nezara viridula (Linnaeus)), and pod borer (Maruca testulalis (Geyer)). The application of NSP, Virgra, and BeBas, as preventive measures and the application of synthetic pesticides based on schedule effectively were suppressed pest population. In contrast, the application of biopesticides and synthetic pesticides based on ET did not suppress the development of major pests. The application of biopesticide based on ET are safe for the survival of natural enemies. Meanwhile, the application of synthetic pesticides can destroy existing natural enemies. Integrated management of NSP, Virgra, and BeBas, that are applied preventively are potential to be innovative technology for controlling the major mungbean pest to replace synthetic pesticides.

Abstract

Megalurothrips usitatus (Bagnall), is the main pest on mung bean causing crop failures, thus the objective of this study was to determine the proper mung bean planting time and timing of thrips control, with minimal risk of yield loss. This experiment was conducted at Muneng Research Station, Probolinggo, East Java during dry season of 2015. This research was conducted using a split-plot in completely randomized design with planting time as the whole plot and pest control time treatment as a sub-plot with 2 repetitions. There were six planting time as the whole plot: first planting 20 May 2015, second planting 30 May 2015; third planting 9 June 2015; fourth planting 19 June 2015; fifth planting 29 June 2015, and sixth planting 9 July 2015. While, the pest control time treatment was done with an active agent fipronil insecticide as a sub-plot which consists of 4 treatments: (1) without insecticide treatment during vegetative and generative phase, (2) insecticide application during generative phase only, (3) insecticide application during vegetative phase only, and (4) full insecticide treatment during vegetative and generative phase. The results showed that the symptom of thrips attack began to appear 21 days after planting (DAP) by observing initial curling of trifoliate leaves. The thrips population per plant increases with increasing plant age. The highest populations of thrips were found on the second planting time (end of May) combined with no control during vegetative and generative phase, which is 17.8 individuals/plant at 18 DAP. The highest yield lost, was found on first planting time (90.2%) and second planting time (85.6%), if there is no control during vegetative and generative phase. It is indicated that in May become the appropriate time as a critical period of mung bean against thrips attack. From this study it can be concluded that to reduce the risk of high yield losses due to thrips attacks is to avoid from planting green beans in May. In thrips endemic areas, pest control at the beginning of plant growth and during the vegetative phase is a determining factor for the yield of mung bean. The season of “bediding” can be a warning sign for farmers before thrips infestation and to immediately take pest control measures.

Abstract

The structure of agricultural landscape, both of its composition and configuration can affect the presence of predators and parasitoids, and influence the effectiveness of biological control. This study was aimed to examine the relationship between landscape structure and the diversity of Hymenoptera parasitoids in long bean fields in Bogor, West Java. In total, six long bean fields were selected and quantified within a radius 500 m from long bean field. In each long bean field, Hymenoptera parasitoids were sampled in a 50 m x 25 m plot using direct observation. The research result found 283 individuals of Hymenoptera parasitoids belong to 9 families and 31 species. Based on the Mantel test, the landscape structure did not affect the species composition of parasitoids in long bean. However, at class scale, landscape composition especially crop field and semi-natural habitat have an effect on parasitoid abundance. Agricultural landscape with higher patch number of crop fields tends to have higher parasitoid abundance. It indicates that landscape composition at class scale is more affected to Hymenoptera parasitoids than at landscape scale.

Abstract

Land-use change from forest to plantation can cause the loss of various types of insect diversity group, one of which is the beetle group. Curculionids or weevils is one of the largest families in the Order Coleoptera due to its adaptability in almost all habitats in nature. This research is aimed to study the effect of seasonality on species richness and the abundance of weevils in oil palm and rubber plantation in Hutan Harapan and Bukit Duabelas National Park, Jambi. Sample was collected in the dry season and rainy season 2013–2014 by fogging method using pyrethroid knockdown insecticides. In each land use, 4 observation plots were erected with selected 3 points as a subplots, so there are 16 plots or 48 subplots in total. The results showed that 1.761 individuals of weevils from 9 subfamilies and 45 morphospecies. Based on analysis, seasonal difference did not affect species richness and abundance of weevils, while land-use types affect abundance of weevils. Analysis of similarity using Bray-Curtis Index showed 4% of similarity in two land-use types, and 46% of similarity between two seasons. The diversity index in oil palm plantation were lower than rubber plantation. The most dominant species that can be found in both land-use types is Elaeidobius kamerunicus Faust., while Rhynchophorus sp.01 is only found in oil palm plantation, and Curculio sp.04 is only found in rubber plantation.

Abstract

Sycanus aurantiacus Ishikawa & Okajima, found in Bali, was first described in 2007 as a new harpactorine species based on morphological and biological characteristics; however, its genome has not yet been sequenced. In this study, we examine the mitochondrial cytochrome oxidase subunit I (MtCOI) nucleotide sequence of S. aurantiacus in order to determine whether it represents a new harpactorine species. A sample from Pancasari, Bali, Indonesia was collected at the same location S. aurantiacus was first discovered in 2007. The selected mtCOI gene (650 bp) was successfully amplified using mtCOI primer pairs LCO1490 and HCO2198, and the resulting MtCOI sequence of the S. aurantiacus sample was compared with those from other hapactorine species recorded in GenBank. This comparison revealed low genetic similarity between S. aurantiacus and most other harpactorine species worldwide, except for the Genus Sycanus (JQ888697) from USA whose mtCOI shares approximately 91% similarity with the Pancasari sample. Phylogenetic analysis indicated a close genetic relationship between Sycanus from Bali and the Genus Sycanus (JQ888697) from the USA. The mtCOI sequence of S. aurantiacus had not been recorded previously, and our comparison with existing Sycanus sequences provides support to the understanding that S. aurantiacus is indeed its own species.

Abstract

The African oil palm weevil, Elaeidobius kamerunicus is an effective pollinator of oil palm. Each individual palm produces exclusively male or female inflorescence so that the success of pollination depends on the ability of the pollinator to transfer pollen from male to female flowers. The objective of this research was to study the amount of pollen carried by E. kamerunicus between male and female inflorescences (pollen load) and the amount of pollen carried on each part of the weevil’s body (pollen distribution). Fifty each of male and female  E. kamerunicus individuals were collected from male and female flowers on trees in 3 locations: Siantar (North Sumatra), Dramaga (West Java), and Morowali (Central Sulawesi). Data on pollen load and pollen distribution on the weevil’s body were analyzed using ImageJ software. Results show that E. kamerunicus individuals collected more pollen from male flowers than from female flowers. In addition, male insects carried more pollen on their bodies than female insects. Pollen distribution on weevil body parts was highest on the elytra, followed by the thorax, abdomen, legs, and head respectively.

Abstract

Tetranychus kanzawai is a species of mite that can cause agricultural crop losses of about 60–90%. One way to control pests that are environmental friendly is to use the predatory beetle Stethorus punctillum. This study aims to determine the demographic statistics, preferences, and functional response of S. punctillum on T. kanzawai. Observation of the S. punctillum biological using 100 eggs, observations were made of the number of individuals living until adult females produce offspring. Preferences of S. punctillum using 50 eggs and 50 nymphs and T. kanzawai adults, observations were made on the number of  T. kanzawai preyed by instar larvae I, II, III, IV, and S. punctillum adults. Functional response is done by giving S. punctillum prey as many as 30, 40, 50, 60, 70, 80 eggs T. kanzawai, observations made on the remaining number of eggs. S. punctillum eggs last for 7.01 ± 0.72 days. First instar larvae lasted for 4.84 ± 0.51 days, second instar 3.16 ± 0.52 days, third instar 3.00 ± 0.27 days, and IV instar 2.48 ± 0.50 days. Females lay eggs 64.47 ± 2.37 eggs. Gross reproduction rate (GRR) of S. punctillum 64.29 individuals/generation, net reproduction rate (Ro) of 17.18 individuals/female/generation, intrinsic accretion rate (r) of  0.27 individuals/female/day, average the generation period (T) is 62.41 days, and the double time (DT) is 2.51 days. The data shows that S. punctillum has a preference for T. kanzawai egg stages and type III functional response curves with Th 7.68 minutes and a 0.22 eggs/minute.
