Abstract

Sciarid fly (Bradysia ocellaris Comstock) population growth and its distribution in the mushroom house was studied. Insects were collected using sticky yellow traps laid on 21 stations in the house over 18 weeks. At the first time, insects population was low. After that, insect population grew and reached at a maximum level in the 8th week. In subsequent weeks, insect population fluctuated. In the other hand, insect population dispersal also occured in the house. Based on spatiotemporal analysis using contour map and semivariogram analysis, insect population showed aggregation pattern, in a small group is called subpopulation. This was related to biological characters of insect such as eggs oviposition in mass and short flights.

Abstract

Bradysia ocellaris Comstock is an important insect pest of oyster mushroom at Bandung. Eggs are oval, 0.44 ± 0.12 mm in length, 0.26 ± 0.08 mm in width, and translucent. Larvae are worm-like, legless, translucent, and capsule distinctive black. Larvae consist four instars. Pupae are obtectate, 2040 ± 0.22 mm in length, and 0.69 ± 0.10 mm in width. Adults are small, females 2.58 ± 0.28 mm and males 2021 ± 0.28 mm in length. Life cycle is 16 -6 26 days. Larvae feed on media, mycelia and fruit bodies.

Abstract

Monitoring of the red flour beetle (Tribolium castaneum Herbst) population by using semiochemical. based bait is important for supporting integrated pest management program. The baits were formulated succesfully using wheat bran as carrier and vegetable oils such as corn oil, soybean oil and palm oil as kairomone, and 4,8 dimethyl decanal. (DMD) as aggregation pheromone. The beetles responded to all baits both in laboratory and warehouse. The level of attractancy on bait loaded DMD is higher than others. Therefore loading of DMD is obligatory.

Abstract

Nilaparvata lugens Stål. is an essential pest in rice plants. This pest attack can reduce crop yields and even crop failure. This research was conducted to obtain secondary metabolites that are effective in controlling brown planthopper (BPH). A randomized block design was used to test the effectiveness of secondary metabolites against BPH. The treatments tested were secondary metabolites produced by eight isolates of fungi consist of three concentrations: 5, 10, and 15%. Water and imidacloprid insecticide were used as control. The eight isolates were: J11 (Aspergillus sp.), J22 (Lecanicillium saksenae), J34 (Myrothecium sp.), J35 (Beauveria sp.), J41 (Fusarium sp.), J56 (Fusarium sp), J60 (Simplicillium sp.), and J65 (Curvularia sp.). Each treatment was repeated three times. The variables observed were mortality and time of death of BPH. Data were analyzed using the F test and followed by a DMRT if significant differences existed. The results showed that the secondary metabolites of the Lecanicillium saksenae, Myrothecium sp., and Simplicillium sp. fungi effectively controlled BPH pests by 80‒100% within 3.22‒5.47 days. The fungus L. saksenae, Myrothecium sp., and Simplicillium sp. contain insecticidal compounds, clogging the insect spiraculum, antifeedant, repellant, and antimicrobial.
