AbstractPests fruit fly attacks could be an obstacles to the export of fruits. Heat treatment is needed to disinfest the fruit fly without affecting the fruit quality and safe for health. The objectives of this research were (1) to analyze the mortality of Bactrocera papayae fruit flies by in-vitro and by in-vivo, and (2) to analyze theeffect of vapor heat treatment (VHT) and storage temperature on quality of Arumanis mango. The results showed that the 100% mortality in-vitro of fruit fly B. papayae at temperature 46 oC was 10 minutes. While 100% mortality in-vivo at temperature 47 oC was 20 minutes. Exposure time of VHT, storage temperature,and their interaction didn’t significantly afffect weight loss, total soluble solid, hardness, but significantly affected vitamin C. VHT didn’t cause physiological damage which the fruit is still undergoing a process of normal respiration. The fruits on storage temperature of 13±2 oC can last for 18 and 28±2 °C just can last for9 days. VHT at temperature of 47 °C for 25-30 minutes was effective to disinfestation of fruit flies infested inside the Arumanis mango and VHT followed by low temperature storage (13±2 oC) was able to maintain mango quality during storage.

Currently, most cockroach control in urban environment relies on bait application. Aversion of some commercial bait by cockroach cause failure to control cockroach problems. Developing local bait can improve this situation. This research was aimed to find proper combination of some cockroach diet to be formulated in effective bait. Research was conducted in Department of Plant Protection, Bogor Agricultural University, since November 2007-March 2008. Combination of peanut butter, chicken egg, and strawberry jam seem to be a candidate of effective bait for local cockroach.

We studied the distribution of the Yellow Crazy Ant (Anoplolepis gracilipes) Smith (Hymenoptera: Formicidae) in Bogor Botanical Garden (BBG). Biological invasions by A. gracilipes can negatively impact other species. Individual nests of this ant can form supercolonies within which aggression is absent, intraspecific aggression occurs between workers from different supercolonies. The aim of this research was to study aggression between and resource discovery of different A. gracilipes supercolonies in BBG. Intraspecific aggression was calculated as three different aggression indices obtained by performing intercolonial arena encounters. Resource discovery was measured as time until honey baits in known distances to colony entrances were discovered. In 2013, we encountered five spatially distinct nest clusters of A. gracilipes in BBG, which cover ca. 25% of its area. Aggression tests showed that workers from KRB 1 were significantly more aggressive towards each other. The absence of intercolonial aggression between three of five nest clusters suggested that they actually belong to the same supercolony. On average, A. gracilipes needed less than 1 hour to find the food on bait plate in 20 m distance. We found 3 supercolonies of A. gracilipes which derived from 5 spatially distinct cluster of nests in BBG.

Control of postharvest pest on cocoa beans during storage is generally conducted by fumigation with phosphine. Long-term exposure to phosphine and improper fumigation practices could stimulate the development of resistant strains against phosphine. The aims of this research were to know the resistance status of red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) against phosphine from cocoa bean storages in Makassar, South Sulawesi and to conduct the field efficacy test of phosphine against insects resistant strain to confirm their resistance status. The study was conducted by collecting T. castaneum from five different cocoa beans storages in Makassar. Resistance status was tested in the laboratory using the standard method recommended by FAO and by conducting field efficacy test on adult strains resistant to phosphine. The results showed the presence of insect resistance to phosphine. Adult, pupae, and larvae of T. castaneum were found to be resistant to phosphine with the resistance factors of 1.15–8.08, 1.58–13.63, 1.53–3.25, respectively. The results of field efficacy tests showed that dosage 2 tablets/m3 was effective in controlling resistant strain of adult, pupae, and larvae of T. castaneum.

Chrysanthemum (Chrysanthemum indicum) as one of horticultural commodities has a good prospect to be developed as source of country revenue. The export of cut flowers of chrysanthemum from Indonesia tends to increase year by year. However, Thrips parvispinus Karny (Thysanoptera: Thripidae) which is major insect pest of chrysanthemum often attacks this flower in the field until postharvest causing the decrease of quality of flowers. The poor quality of cut flowers of chrysanthemum including the presence of T. parvispinus will be rejected by foreign businesses. Therefore, control measures of this insect pest by quarantine officers are important. Treatment can be done using liquified formulation phosphine fumigant. The objectives of this study were to determine the concentration of liquified formulation phosphine and exposure time which will were effectively kill T. parvispinus and to evaluate the quality of cut flowers of chrysanthemums treated with phosphine fumigant. T. parvispinus was exposed to liquied formulation phosphine at 9 concentrations (0, 25, 50, 75, 100, 125, 150, 175 and 200 ppm) with 3 exposure times (1, 3, and 6 hours). Moreover, validation test of concentration nd exposure time of liquified formulation phosphine on cut flowers of chrysanthemum was conducted to evaluate the quality of chrysanthemum cut flowers of treated with phosphine fumigant. Results showed that liquified formulation of phosphine at concentration of 200 ppm and on 1 hour of exposure time completely killed T. parvispinus by 100% mortality. At 200 ppm and exposure time until 6 hours did not affect the quality of cut flowers of chrysanthemum.

Ants provide important ecosystem services such as predation and decomposition. The ecosystem services in different land-use systems will be influenced by the dominant ants species in those areas. The objectives of this study were to investigate the impact of land use types on ant community structure and to measure the ecosystem service provided by ants. The study was done in several land-use types in Jambi i.e. secondary forest, jungle rubber, rubber plantation, and oil palm plantation during April–Juni 2014. In each land-duse type, four plots were selected with a size of 50 m x 50 m for each plot. Each plot consisted of five subplots of 5 m x 5 m. In each plot, a tree was chosen for further observation on ant diversity and its ecosystem services. Ants were collected with the baiting method using Corcyra cephalonica larva that was laid on a plastic plate and put on the ground and on the tree stem. Ecosystem services were measured by observing the number of C. cephalonica larvae that were carried or removed by ants within a 1-hour observation. The results showed that the forest has the highest ant species richness than other land-use types. Land-use types have no impact on ant species richness but affected ants species composition. The highest removal C. cephalonica by ants was found in the secondary forest. Ants that played important role in ecosystem service in this study as predator were Achantomyrmex sp. 01, Aenictus sp.01, Carebara sp. 01, Tetramrium sp. 02, O. denticulata, Tetramorium sp. 03, Crematogaster sp. 02, A. gracilipes and Rhoptromyrmex sp.01.

Indonesia has seen an increase and widespread reports of resistance among stored-product insect pests to phosphine. The use of Syzigium aromaticum (clove oil) as an alternative fumigant may be a useful strategy to control infestation by phosphine-resistant varieties of stored-product insects. The objective of this study was to examine the effectiveness of whole (unfractionated) clove oil as well as its component fractions as a fumigant and repellent against the red flour beetle (Tribolium castaneum (Herbst)), and to develop a simple fumigant formulation for this purpose. The experimental design used to test the effectiveness of clove oil and its fractionation was a completely randomized design (CRD). Meanwhile, testing the effectiveness of tablet formulations was carried out by factorial CRD. Fumigation test results gave LD50 and LD95 values of 0.234 and 1.142 ml/l respectively, for crude clove oil used in a fumigation chamber against T. castaneum. An n-hexane fraction of clove oil tested under the same conditions was more lethal, causing 95% mortality of T. castaneum at the dose of 0.801 ml/l during fumigation. Finally, tablets containing a set proportion of clove oil and naphthalene (1:1) reached LD91 against T. castaneum after 7 days’ fumigation.

Cocoa (Theobroma cacao) is one of the important commodities in Indonesia. The quality of cocoa beans has decreased during storage, one of which is due to the attack of Araecerus fasciculatus (De Geer). This pest attack can be overcome by fumigation that is safe for the environment through the use of essential oil. The study aimed to examine the mortality and repellent effects of kaffir lime leaves essential oil (KLLEO) to A. fasciculatus and to analyze the compound content of active fraction KLLEO using GC-MS. Research stages included maintenance and insect rearing, toxicity and repellency tests, fractionation, and analysis of active fraction compounds of essential oils. The study was designed using CRD with 6 treatments and 4 replications. The n-hexane fraction of KLLEO caused the highest mortality of A. fasciculatus adults after 72 hours of fumigation. The LD50 and LD95 values of the n-hexane fraction of KLLEO were 0.30 and 1.66 ml/l air, respectively. The dose at 1 ml/l air caused the highest mortality of A. fasciculatus adult by 73.75%. Examine using an olfactometer, KLLEO has high repellency against adult A. fasciculatus with the value of the repellency index reaching 100% at 1 ml/l air. The most dominant compound in the n-hexane fraction of KLLEO was the citronellal. Therefore, the KLLEO has some potential to be expanded as a botanical fumigant towards A. fasciculatus.

Decomposition is an important process in nature, as it can break down organic matter into smaller particles and nutrients. Nutrients are returned to the environment and can be reused by other organisms. One important organism that plays a role in the decomposition process is termites because termites are able to decompose organic matter such as wood in all habitats. Different termite habitats can be seen in terms of different types of land use. Some types of land use, such as natural forests, secondary forests, palm oil plantations, and settlements, can be used as a test site for wood decomposition by termites. All types of land use can be found in Dharmasraya Regency, West Sumatra Province. The purpose of this study was to study the decomposition of wood by termites in several different types of land use. Four types of land use are selected from habitats with the least disturbed conditions to the extent of high habitat disturbances, namely natural forests, secondary forests, palm oil plantations, and settlements. The study was conducted in Dharmasraya Regency, West Sumatra Province. The research method uses pine wood bait (Pinus merkusii), measuring 1.9 cm x 1.9 cm x 25 cm. The wooden bait is winded for seven days, and the wood bait is weighed to gain its initial weight and measured moisture content. Furthermore, wood bait that has been installed is observed and re-weighed to gain final weight and measured water content. The results showed that deforestation in Dharmasraya, West Sumatra had an effect on reducing wood decomposition by termites. Five (5) termite species were found in wood bait, including Pericapritermes sp.1, Microtermes sp.1, Schedorhinotermes sp.1, Macrotermes gilvus, and Coptotermes curvignathus.
