Stored product insect can cause consumer rejection and economic loss due to quality concerns and phytosanitary regulation. Insect traps have been regularly used as a control method, however its effectiveness on controlling stored copra meal insect pests is not yet known.This study was carried out to compare the effectiveness of three types of insect traps for detection of insect pests of copra meal.The three types of insect traps were pitfall trap, probe trap, and ultraviolet (UV) light trap (blacklight and LED-light emiting diodes). Research was conducted at Laboratory of Entomology SEAMEO BIOTROP, Bogor and two storage facilities of copra meal in North Sulawesi. Laboratory experiment was conducted using completely randomized design with two factors and four replications. The first factor was the types of insect traps (pitfall trap, probe trap, and probe trap with UV LED) and the second factor was insect species (Lasioderma serricorne (Herbst) and Tribolium castaneum (Fabricius)). The experiment at storage facilities was conducted with nested block design where the insect species trapped were nested in the insect traps. The result of laboratory experiment showed that the probe trap captured more insects (30.4%) significantly higher than pitfall trap (17.1%), however there was no significant difference of number of insects trapped in probe trap with and without UV LED. In addition the probe trap captured more T. castaneum and Tenebroides mauritanicus than other type of insects trap, but probe trap with UV LED was more effective to detect L. serricorne and Necrobia rufipes (Fabricius) in the stored copra meal.

Wood-based packaging material is usually made from low-quality kind of wood, making it a potential medium for carrying or housing wood-destructive organisms. The objective of this research was to investigate the toxicity of ammonia as a fumigant for controlling the dry-wood termite, Cryptotermes cynocephalus. Ammonia was applied as ammonium hydroxide (NH4OH) 25%, which was placed inside the fumigation chamber. At 2.25 cm wood thickness, toxicity tests were performed using 3 levels of NH4OH doses (0, 700, and 3800 mL/m³) and 4 levels of exposure (4, 6, 8, and 10 hours). The toxicity of ammonia fumigant at 1.25 cm wood thickness was assessed using 6 dose levels of NH4OH (0, 200, 378, 587, 1732, and 4188 mL/m³) for 4 hours of exposure. The LD50 and LD90 values of ammonia against the dry-wood termite, C. cynocephalus, inside the sengon wood at 2.25 cm thickness after 4 hours of exposure were 3263 mL NH4OH/m³ and 22,781 mL NH4OH/m³, respectively. Moreover, for 1.25 cm wood thickness, for the same exposure duration (4 hours), the LD50 and LD90 values of ammonia fumigant were 541.594 mL NH4OH/m³ and 1432.125 mL NH4OH/m³, respectively. Meanwhile, for 0.25 cm wood thickness, the LD50 and LD90 values were 67.67 mL of NH4OH/m³ and 241.140 mL NH4OH/m³, respectively. In addition, for 2.25 cm wood thickness, the LD50 and LD90 values of ammonia fumigant were lower when the exposure time was longer (2149 and 10,722 mL NH4OH/m³ for 6 hours of exposure, and 1373 and 8705 mL NH4OH/m³ for 8 hours of exposure).

Changes in land use due to deforestation can affect the diversity, composition, and structure of fauna communities, including termites. This study aims to examine the diversity, composition, and structure of the termite community in several land uses. Land uses include natural forest, secondary forest, plantation of oil palm, and settlements in Dharmasraya District, West Sumatra Province. The research was conducted to determine the distribution of species and termite colonies in Dharmasraya District. The research method used observation on the level of habitat disturbance. The observations were conducted on 50 m x 10 m plots. One plot was split into 5 m x 5 m sub-plots, and there were 20 sub-plots in total. Termite samples collected from each plot were identified in the laboratory. This study found 14 species of termites on different land uses in Dharmasraya Regency West Sumatra Province. The level of disturbance of land use types affects the composition and structure of termites within it, especially from taxon groups and their food groups, and there are similarities in termite species composition in natural forests and secondary forests and and also similarities on termite species composition in oil palm plantations and settlements.

Macrotermes gilvus (subterranean termite) can play dual roles as decomposers of natural wood and pest in plantations and urban area. The damages caused by termites in the urban area reaches 35% and in the wood industry can reach 40%. Nowadays, termite control is still carried out by the application of synthetic termiticide. In termites’ case, environmental pollution issue is more important than the resistance of termite to termiticide, so it’s necessary to find alternative termiticide from natural materials. This study examined the potential of clove essential oils to control M. gilvus with two methods. The test methods were oil residue on filter paper and soil in a glass tube H. Clove essential oil on filter paper was applied and dried for one minute, after that put in the petri dish. For soil treatment, the soil was soaked with clove essential oil for one hour and dried for one day, after that the soil treatment put into the bridge tube. Each method was infested by 50 termites with ratio 90% workers and 10% soldiers. Termite mortality on treated filter paper was observed after 72 hours, and on treated soil were observed daily until 7 days. The result showed that clove essential oils caused mortality of M. gilvus more than 90% after consumed and contacted on treated filter paper and contacted on treated soil with concentration 0.80% and 1.20%, respectively. Based on the results, clove essential oil has the potential to be developed and can be used as an alternative against termites, that was environmentally friendly.

The infestation of Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) results in the reduction of flour weight, changes in flour color, and a musty odor in stored materials. One alternative control method is using patchouli extract (Pogostemon cablin), which has insecticidal activity. The extraction methods and the application techniques in controlling storage pests influence the effectiveness of the extract as a botanical insecticide. The study aims to examine the differences in yield, composition, content, toxicity, and repellency levels of patchouli extracts obtained using various extraction methods for controlling T. castaneum. The study employs three patchouli extraction methods: maceration, steam-water distillation, and ultrasonic extraction. Three application techniques are used in this study: fumigation, topical and residue. The observed variables include the content and composition of the extraction yield, toxicity levels, and repellency levels. Data analysis is performed using probit analysis to determine LD/LC50 and LD/LC95, and ANOVA at 5% level, followed by Tukey’s test. The research results indicate that the extraction method assisted by ultrasonic waves yields the highest extraction yield. However, patchouli extract obtained through the distillation method exhibits the highest toxicity effects when applied with topical and residue techniques. The LC50 and LC95 values of patchouli extract obtained via distillation are 0.804% and 1.541% while the LD50 and LD95 values are 49.140 μg/imago and 135.729 μg/imago. The main compounds found in patchouli extract obtained through distillation are patchouli alcohol, α-guaiene, δ-guaiene, and seychellene. Patchouli extract obtained through distillation has the potential to act as a contact insecticide and repellent against T. castaneum.
