Abstract

Kumchura (Kaempferia galanga, L.) rhizome, a herbal medicine and condiment used in many Asian countries, was known to possess licicidal quality. To ensure whether this quality extend to other insects, kumchura rhizome preparation was applied to eggs, larvae and adults of the melon fly, Bactrocera cucurbitae, Coquillet. Crude preparation of the rhizome was mixed with larval diet which was also served as a common artificial egg-hatching medium. The preparation proved to be ovicidal at minimum concentration ratio of 1 :4, kumchura:larval diet. No such larvicidal effects were seen at the same ratio, the effects observed were larval development inhibition and delay. In the repellency tests, proportionally less melon flies were found on diet containing kumchura, but no effect on oviposition was observed.

Abstract

To know daily periodicity attendance of rice bug (Leptocorisa oratorius F.) in response to sixth-day-decaying crab, an experiment was conducted in four consecutive days in May 1997 in Gamping, Special Territory of Yogyakarta. The experiment consisted of 17 treatments and 3 replications arranged in randomized completely block design. Seventeen hourly observations (treatments) were made on rice bugs attendance on the decaying crab by direct counting as well as the relative humidity and temperature from 5 am to 9 pm. The result of the experiment showed that the peaks of rice bug attendance were from 10 am to 6 pm, while the highest one was at 5 pm (20 rice bugs).

Abstract

Pheromones are chemical substances used by insects to communicate within their species. Our understanding about pheromones' chemistry, their functions and their overall performances over insect behavior provide us with wealth of information that lead to their use for insect pest control. The use of insect pheromones, particularly sex attractants, is quite advanced, but little information is available about Indonesian indigenous harmful insects' pheromones. More research and investigations need to be done to obtain target-specific substances rather than simply utilize imported products. Their implementation into Integrated Pest Management using farmers-oriented technology should be considered.
