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

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

The red flour beetle, Tribolium castaneum (Herbts) is a major pest of flour from various grains. The infested flour is discoloured and will emit a disagreeable odour due to the secretion of benzoquinone from the insect’s abdominal glands. Considering the economic losses effected by T. castaneum, new alternative control measures are needed for this pest. This study sought to determine the host preferences of T. castaneum from amongst six kinds of flour to assess their vulnerability to infestation. The research was conducted in the Plant Pest Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya. The host preferences of T. castaneum were examined using a six-arm olfactometer. Feeding preference tests were performed for a duration of 12 hours at 200 ml/minute airflow in each chamber-arm, followed by oviposition preference observations one week later. Feeding preference was calculated for the total pool of adults observed, segregated by sex, whereas oviposition preference was calculated as the number of eggs laid. Flour nutrition (proximate composition, phenolic content, and riboflavin content) were analyzed. Our results showed a feeding preference by T. castaneum for bran, soy and tapioca flour was greater over wheat, corn, and white gelatinous rice flour, while for oviposition, bran flour was the most preferred.

Abstract

The sweet potato whitefly, Bemisia tabaci (Gennadius) is a cosmopolitan pest on various types of agricultural crops. The whitefly is able to cause damage to plants by directly consuming plant parts using stylet and as a vector of plant viruses. Red chili (Capsicum annuum) and tomato (Solanum lycopersicum) plants are important horticultural plants that are often infested by B. tabaci. Whiteflies are known to reproduce with copulation that produce male and female offspring and without copulation that produce male offspring. The purpose of this study was to determine the reproduction ability of B. tabaci with and without copulation in red chili pepper and tomato. Adult of B. tabaci was taken from a greenhouse in Cikabayan, IPB Dramaga. One female who just emerged from the pupa or final instar nymph was invested in red chilli and tomato plants in polybags to determine the B. tabaci offspring produced without copulation. The same method was also done for whitefly with copulation, but using a pair of adult whitefly (male and female). Each treatment was repeated 5 times. Observations were made every day on the number of eggs produced by one female adult per day, the egg incubation period, the length of the nymph period for each instar, pupa, and adult. The results of this study showed that the fertility of B. tabaci which reproduces with and without copulation in tomato plants was higher than in chili pepper plants, but there was no difference in life cycle and sex ratio.

Abstract

Fruit flies attack mostly on fruit vegetables and fresh consumed fruit. Symptoms of damage is decaying of fruit surface resulting to fruit falling. Data on the diversity of fruit fly species in South Sumatra and their patterns of presence have not been widely reported. The aim of the research was to study diversity and presence patterns of fruit flies based on the host and trap. The research was conducted using a survey method in 9 cities and districts in South Sumatra Province. Fruit flies were collected by collecting infected fruit and using traps containing cue lure (CL) and methyl eugenol (ME). There were 24 types of plants observed, including fruit, vegetables, and fruit for consumption. Fruit flies identification was carried out by observing external morphological characteristics. The identification resulted 18 species in which CL and ME trap 10 and 7 species, respectively. One species (Bactrocera latrifons) did not trapped in both traps. Among 18 species, 7 of them were obtained from fruit collections. The type of attractant affected species diversity and number of fruit flies caught. B. latifrons was only found in fruit rearing. The altitude of observation area affected fruit flies diversity. All species were found in the lowlands, except B. ascitus, B. cilifera, and B. latrifons. In the moderate lands and highlands, the number of fruit fly species found was less than in the lowlands.

Abstract

The presence of Spodoptera frugiperda J.E. Smith or fall armyworm (FAW) have now detected in West Java. However, no information is available on their attack intensity even though the data is crucial for the implementation of appropriate control methods. The investigations were carried out in Garut (Limbangan, Wanaraja, dan Banyuresmi) and Tasikmalaya (Sukaratu) Regencies from 25 to 27 February 2020. At each location, 100 plants were selected for recording observations on leaf damage following the Davis Scale. The results showed the attack intensity in Wanaraja (34,78%), Banyuresmi (34.78%), and Sukaratu (39.89%) showed moderate damage. On the other hand, Limbangan one of the corn production center, showed high damage with the intensity of the pest up to 52.78%. The attack intensity of FAW tends to correlate with their attack level. This means that plant damage levels increasing at higher attack levels.
