Abstract

Gmelina arborea is one of the important trees for forest plantation. It is used for pulp, paper and plywood. Considering that G. arborea is an exotic type, this species has highly risk of receiving pest and diseases. This research was aimed to study the biological characteristics, attack pattern and distribution of stem borers. Studies were conducted in PT. Sumalindo (East Kalimantan). The sampling plot was 20x20 m2, and the plants were stratified based on the plant age. Observations were directed to determine the species of stem borers and the damage they caused. Xyleutes ceramica and Acalolepta rusticatrix were documented attacking G. arborea, with their damage intensity of 13% and 54.8%. These insect attacked 22% and 64.4% of the plant plantation.

Abstract

Increasing the reproductive capacity through increasing plant growth and nutrition is one plausible mechanism of resurgence. This research was intended to determine the effect of deltamethrin on plant vigor and nutrition contents. The experiment was carried out outdoor. The treatments tested were deltamethrin (50 ppm), buprofezin (100 ppm), and control (water). Insecticide applications were applied one time (at age 26 d or 50 d) and two times (at age 26 and 50 d). Deltamethrin applications as many as two times did not increase the total chlorophyll and the photosynthesis rate, nutrients (total nitrogen, total protein, total sugar, total reducing sugar at aged 26 d, and sucrose), growth (plant height and number of tillers), and yield (number of panicles). However, application of deltamethrin at aged 26 d increased the amount of asparagine. Asparagine is known to be associated with the feeding rate of Nilaparvata lugens stimulation. Therefore, increasing level of asparagine after application of deltamethrin at sublethal concentration was considered as one of the factors that might be involved in the mechanism of N. lugens resurgence.Salah satu mekanisme resurjensi adalah peningkatan reproduksi hama melalui peningkatan nutrisi dan pertumbuhan tanaman. Penelitian ini dimaksudkan untuk melihat pengaruh deltametrin terhadap kandungan nutrisi dan vigor tanaman. Pengujian dilakukan di lapangan. Perlakuan yang diuji adalah deltametrin 50 ppm, buprofezin 100 ppm, dan kontrol (air). Aplikasi insektisida dilakukan satu kali masing-masing pada umur tanaman 26 dan 50 hst dan dua kali pada umur 26 dan 50 hst. Aplikasi deltametrin sebanyak dua kali tidak meningkatkan total klorofil dan laju fotosintesis, nutrisi (total nitrogen, total protein, total gula, total gula reduksi pada 26 hst, dan sukrosa) kecuali asparagin, pertumbuhan (tinggi tanaman dan jumlah anakan), dan hasil (jumlah malai) tanaman. Oleh karena asparagin berperan sebagai pemacu laju makan Nilaparvata lugens, maka peningkatan kadar asparagin tanaman setelah aplikasi konsentrasi subletal deltametrin diduga sebagai salah satu faktor yang terlibat dalam mekanisme resurjensi N. lugens

Abstract

Development of insect resistance to insecticide has been the major driving force for the development of new insecticides. Awareness and demand from public for more environmentally friendly insecticides have contributed in shifting the trend from using broad spectrum to selective insecticides. As a result, scientists have looked for new target sites beyond the nervous system. Insect growth regulators (IGRs) are more selective insecticides than conventional insecticides, and ecdysone agonists are the newest IGRs being commercialized, e.g. tebufenozide, methoxyfenozide, and halofenozide. Ecdysone agonists bind to the ecdysteroid receptors, and they act similarly to the molting hormone 20-hydroxyecdysone. The binding provides larvae or nymphs with a signal to enter a premature and lethal molting cycle. In addition, the ecdysone agonists cause a reduction in the number of eggs laid by female insects. The ecdysone agonists are being developed as selective biorational insecticides. Tebufenozide and methoxyfenozide are used to control lepidopteran insect pests, whereas halofenozide is being used to control coleopteran insect pests. Their selectivity is due to differences in the binding affinity between these compounds to the receptors in insects from different orders. The selectivity of these compounds makes them candidates to be used in combinations with other control strategies to develop integrated pest management programs in agricultural ecosystems.

Abstract

Recent reviews on Dorsalis and Dacine fruit flies had implication on host-insect inventory, including in Indonesia. Update is needed because of these changes and due to the rising of fruit and vegetable trade within islands, as well as with neighboring countries. Fruits were collected over a 3-year period from 24 provinces of Indonesia, covering areas from Aceh to Papua. This work was done specifically to obtain detailed information regarding the host range of the important species of Bactrocera spp., Atherigona orientalis, and Dacus longicornis, as well as Adrama determinata. Male lure Steiner traps to attract fruit flies were used in this study as an additional method to support species variation.Atotal of 1125 fruit samples were collected from many locations. Thirty five plant species from 18 families were recorded as fruit fly hosts and 27 plant species were new report as specific host for certain species of fruit fly. A larger array of host plants for fruit flies in Indonesia than reported before suggests the importance of effective quarantine measures to limit the spread of harmful fruit fly and to prevent the accidental introduction of invasive alien fruit fly species from other countries.

Abstract

Nilaparvata lugens is the type of insect pest whose resurgence is induced by insecticides. Deltamethrin is an insecticide commonly used by farmers to control pests other than N. lugens on rice. This research was conducted to determine the effect of sublethal concentrations and application frequency of deltamethrin on subsequent growth and development of third instars of N. lugens. The selected concentrations were 50 ppm (LC25) and 225 ppm (LC50), and the frequency of applications ranged 1–3 times. Each concentration was applied to the third instars of the parent generation (one time), the parent and their first offspring (two times) and the parent, their first and second offspring (three times). N. lugens used in this experiment was the susceptible population derived from the laboratory population. Application of deltamethrin on two and three consecutive generations increased nymphal mortality, the population of offspring produced by the surviving adults, and the ratio of treated and control females in producing the offspring. Increasing the frequency of application increased the ratio, and the females received three applications produced nymphs 2.65 times more than the control females. The two sublethal concentrations did not have significant impact on the above parameters. Furthermore, the interaction between concentration and frequency of application was absent. These findings suggest that several applications of deltamethrin at sublethal concentrations would contribute to the resurgence of N. lugens.

Abstract

Khapra beetle, Trogoderma granarium Evert (Celeoptera: Dermestidae) entered Central Java together with importation of stored products four decades ago. A survey was conducted to detect whether the Kaphra beetle existed in Central Java after they had been fumigated during commodity arrival. If the Kaphra beetle is absent, the data could be treated as the starting point toward declaring a pest free area (PFA) of Kaphra beetle in Central Java. The survey employed the procedure established in Australia, except this survey lasted for 11 months starting from April 2008 to February 2009. Insect traps (Trécé Incorporation, Oklahoma, USA) were placed in eight sites distributed in six districts identified as high risk for Kaphra beetle. The traps were substituted following the label. The traps were checked every 2–4 weeks making the total observations varying from 18–24 times, except one site (eight times). No Kaphra beetle was observed during this detection survey. This finding strongly suggests that Kaphra beetle is not present in Central Java. Survey should be continued to collect data sufficient to declare PFA of Kaphra beetle.

Abstract

The use of insecticides at sub-lethal dosage may induce insect resurgence. Factors contributing the insect resurgence include mortality of natural enemies, mass migration, improvement in plant nutrition, or increase in insect reproductive capacity which works individually or in combinations. This article provides a comprehensive review from recent publications, particularly those dealing with the impact of insecticide applications on plant nutrition and insect reproduction, and function to upgrade our knowledge since most publications in Indonesia were made in the 1980s. The insecticides together with its metabolites and conjugates could function as plant growth regulators, increase absorption, improve the nutritional content, influence the biochemical and ultrastructural aspects of the plant, or protect the plant from stresses. An increase in the nutritional value of the plant would increase feeding rate, fecundity, and longevity of the insects. Furthermore, insecticides could also directly stimulate the reproductive capacity of the insect. All of these impacts might end up in increasing the population of insect after application of certain insecticides. Research findings related to the elucidation on the mechanism underlying the phenomenon of resurgence could be used in considering the registration of new insecticides or extension of the existing insecticides.

Abstract

Bactrocera carambolae was founf on carambola fruit in Yogyakarta Special Province and there were three species of parasitoids, i.e. Fopius arisanus, Agasnaspis sp., and Asobara sp. The population of Agasnaspis sp. and Asobara sp. were very low and was only found in Samas coastal area. F. arisanus was dominant and always found in all observation sites. There was no significant result on their parasitism (for region, F(2,35) = 0.057; p>0.005; for elevation, F(2,35)= 0.704, p>0.05; for habitat, F(2,35)= 0.215, p>0.05). Parasitism of F. arisanus on fruit fly in Yogyakarta Special Province was generally low, i.e. it ranged from 0.5495 ± 0.3843 (in Sleman), to 1.2935 ± 0.8206%. Evaluation of the existence of F. arisanus and augmentation efforts might be needed to improve its ability to parasitize fruit fly in Yogyakarta Special Province.

Abstract

The objective of this research was to know the resistance level of beet armyworm Spodoptera exigua to methoxyfenozide. The lara were collected from the shallot production areas in the districts of Nganjuk (East Java), Bantul and Kulonprogo (Yogyakarta Specia Territory) and Brebes (Central JAva). The bioassay used first instars of S. exigua with artificial diets that had been dipped in a series of methoxyfenozide solutions. Larval mortality was recorded at 72 hours after the exposure. The LC50 value of methoxyfenozide for the population from Sanden (Bantul) was the lowest (0.53 ppm) among 16 tested population, therefore it was used as refenrence population to determine the resistance ratio (RR) values of other populations. The RR values of the tested populations varied from 1 to 240,8 times. Population collected from Wanasari (Brebes) was found to have the highest level of resistance of methoxyfenozide as a result of using methoxyfenozide intensively to S. exigua controlling.
