Abstract

Chili peppers (Capsicum annuum), in their many varieties, constitute a culturally and economically important horticultural crop in a number of countries. The Indonesian cayenne large red chili (Capsicum annuum var. annuum) is used widely in Indonesia mainly in cooking. There have been reports of increased infestation of large red chili by insect pests, particularly fruit flies. The aim of this study was to investigate the effectiveness of five edible vegetable oils (palm oil, coconut oil, soybean oil, corn oil, and candlenut oil) and one non-edible vegetable oil (neem oil) in reducing landings, oviposition, and infestation by the Oriental fruit fly (Bactrocera dorsalis Hendel) in large red chili fruits. This lab-based experiment entailed exposure of large red chili fruits to 20 mature B. dorsalis females (14–21 days old) inside a 15-l plastic container. Six separate containers each held 10 large red chili fruits with a single oil treatment in each. Prior to exposure, each of the treated and control large red chili fruits was punctured once with a needle in order to create an opening for oviposition. Results indicate that the coconut oil formulation was most effective in preventing damage from B. dorsalis females, and reducing fruit fly landings, oviposition, and infestation.

Abstract

Pest attack in nutmeg is a cause of major damage both in the field and in storage. Information on the diversity of pest insects in storage, harvesting methods, and good drying needs to be known to reduce the level of damage to nutmeg. This study aims to determine the diversity of insect pests and the percentage of nutmeg damage due to various postharvest treatments. Nutmeg was packed in jute bag and stored for four months under warehouse conditions. Each jute bag containing nutmeg is treated based on the origin of nutmeg (picked from a tree or picked up on the ground), drying method (sunshine or fogging), and shell or without shells with each treatment replicated three times. Sampling of numtag was conducted after four month to calculate the number of each insect species found, determine the insect population, and determine the percentage of damaged seeds. Four insect species were found in nutmeg kernels in almost various treatments. They were Araecerus fasciculatus ((Degeer) (Coleoptera: Anthribidae), Carpophilus dimidiatus (Fabricius) (Coleoptera: Nitidulidae), Oryzaephilus surinamensis (Linnaeus) (Coleoptera: Silvanidae), and Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The dominant species was A. fasciculatus. The percentage of damaged kernels derived from nutmeg kernels fallen on the ground, dried either using sun-drying or smoke-drying, either in-shell or without shell, were higher than the kernels derived from ripe fruitswith various treatments. The recommendation of this research result is good postharvest handling of  nutmeg to prevent insect infestation should be conducted by collecting nutmeg derived from ripe fruits picked from the trees, nutmeg in-shell either sun-dried or smoke-dried, and storing nutmeg in-shell.

Abstract

A field study was carried out to assess the effects of mixed cultivar plantings on grain yields and on the abundance of pests in rice. Increasing plantation species diversity through cultivar mixtures is often claimed to decrease pest problems while stabilizing or even increasing yield, but the effects on pest abundance of planting rice cultivar mixtures in Indonesia have not been extensively studied. We tested for changes in pest abundance in experimental plots planted with five genetically distinct rice cultivars, combined in two different mixture arrangements (seed mix and row mix). These mixes were cultivated in lowland paddy areas, in replicated randomized block designs, during two growing seasons. Pest abundance was measured weekly in all plots, and rice yields were measured at harvest time. The results showed that the average abundance of pests was reduced in plots planted with cultivar mixes, compared to those planted with monocrops comprised of each of the component cultivars. Plots planted with the seed mix showed consistently reduced brown plant-hopper (Nilaparvata lugens (Stål)) abundance compared to monocrops in each growing season, with a relative reduction in pest abundance of 29.83% at the end of season 1 and 6.61% at the end of season 2, respectively. Plots planted with the row mix consistently showed decreased stem borer abundance compared to monocrops in each growing season, with a relative reduction in pest abundance of 100% at the end of season 1 and 1.4% at the end of season 2, respectively. In terms of yield, plant height proved to be a consistent yield component character, correlating positively with plant yield for both seed mix and row mix in both growing seasons. Our results showed higher average yields –and plant heights--for the mixed genotype plots compared to pure genotype stands in 2013. We found a greater relative increase in the yield of seed mix plots than row mix, measuring 7.26% and  4.63%, respectively in 2013. Among the two types of mixtures, seed mix showed higher overall grain yield. Our findings suggest that rice farmers can both increase yield and decrease pest abundance by planting cultivar mixes.

Abstract

Family Curculionidae is a group of beetles (Order Coleoptera) that have an important role in different ecosystems, either as herbivores or pollinators. Land-use change, mainly from natural forest to agriculture area can have negative affect on population of  curculionid beetles. The objective of this research was to study seasonal diversity, both in terms of species richness and abundance of curculionid beetles in different land-use types in Hutan Harapan landscape, Jambi. Curculionids were sampled using fogging methods. The study was conducted in four different land-use types i.e. forest, jungle rubber, rubber, and oil palm plantations in both dry (from May to September 2013) and rainy season (from November 2013 to February 2014). Four plot each of 50 m x 50 m were set up in the four land use types. We found 1762 individuals belonging to 12 subfamili and 118 species curculionid beetle. The most abundant species was found in forest (81 species) and the lowest was in the rubber plantations (20 species). The most common curculionid that were found in each land-use type were Curculioninae sp.21 (forest), Entiminae sp.06 (jungle rubber), Scolytinae sp.09 (rubber plantation) and Elaeidobius kamerunicus Faust (oil palm plantations). The highest abundance of curculionid was in oil palm plantations (853 individual) and the lowest was in rubber plantations (33 individual). Land-use type and vegetation diversity affect species richness but not abundant of curculionids. Analysis showed that different season significantly affect composition of curculionid in the forest but it has no effect in other land use types.

Abstract

Aphids (Hemiptera: Aphididae) are considered as one the most important pest in the world. Some species of aphids were reported as serious pests and plant virus vectors, especially on horticultural crops. Weeds in the agricultural area can serve as an alternative hosts for some aphids which are plant pests or plant virus vectors. The objective of this research was to identify aphid species of weeds in the agricultural production area in West Java and to provide the identification key. Aphids collection was done on the weeds in the agricultural fields in 9 districts of West Java. Aphids were collected from 13 species (5 families) of weeds. The identification of aphid was peformed based on the adult specimens. The research manased to come up with 12 species of aphid on weeds. Three of the 12 collected species were Epameibaphis frigidae (Oestlund), Metopolophium dirhodum (Walker), and Pseudaphis sijui (Eastop) has never been reported in West Java. Six species were known as vectors of plant viruses in agricultural crops. The most commonly found aphid species was Schizaphis graminum (Rondani) in the yard grass (Eleusine indica).

Abstract

Brown planthopper (Nilaparvata lugens Stal) population from Klaten and Yogyakarta may develop into new biotype, but research on the genetic aspect of these populations is limited.  Random amplified polymorphic DNA (RAPD)-PCR technique was used to identify the genetic similarity of brown planthopper population from Klaten and Yogyakarta compared to the population of nearby region. Brown planthopper were collected from paddy field in Klaten, Yogyakarta, Sukoharjo, Boyolali, Karanganyar, Sragen, and Ngawi. Five random primers, namely OPB 01, OPB 07, OPC 04, OPC 08, and OPN 15 were used to amplify the brown planthopper. The present study revealed that five random primers produced DNA band patterns clearly and comparable. However, no primer produced DNA band that could differentiate the brown planthopper population from Klaten and Yogyakarta compare to the population from nearby region. Based on dendrogram, the population from Klaten and Yogyakarta showed a genetic similarity to the nearby population from Sukoharjo, Boyolali and Sragen, except from Karanganyar and Ngawi. Intra-population genetic studies of brown planthopper from Klaten and Yogyakarta may be needed to reveal more genetic characters.
