Abstract

Research has been conducted at farmer’s fruit garden in Cilebut area, Bogor during 1997–1998. The objective is to know the effect of some application techniques of oil distilled from Melaleuca bracteata leaves on trapping fruit fly. Research consisted of three activities, those were the effect of some techniques of application on trapping fruit flies (I) weekly, (2) in two weeks and (3) the effects of some concentrations of methyl eugenol (ME) on trapping fruit fly. All treatments were hung at the fruit trees as high as 1.5 m. Observations were done in the number and gender of fruit flies trapped weekly and two-weekly. Result revealed that melaleuca distilled oil can be applied either by dropping into water or into cotton ball. Melaleuca leaves distilled oil should be applied once in two weeks, since its effectiveness lasted for two weeks only. The minimum concentration of methyl eugenol which could fruit flies effectively was 57%.

Abstract

Research has been carried out at the Pest and Disease Laboratory, Research Institute for Spices and Medicinal Crops, Bogar, in the 1997. Research consisted of three parts, those were; (I) The toxicity of Dens elliptica, Blumea balsamifera, and methaldehyde, by determining the LC50 values, (2) Effect of the leaves of B.balsamifera, Euphorbia tirucalli and Tephrosia vogelii, (3) Effect of the most poisonous plant as ovicides. Result showed that D.elliptica was the most poisonous material to golden snail with its LC50 value was 400ppm, but it was still under the toxicity value of methaldehyde (11. 78 ppm). There was no significant difference among B.balsamifera, T.vogelii and E. canaliculata, but extract of B.balsarnifera tended to be better material among those plant extracts tested. The extract of D.elliptica did not affect egg hatching of golden snail.
