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.

Abstract

Research on the effect of azadirachtin A isolated from neem tree (Azadirachla tndica A Juss) on msect Dolleschalia polibete. the most poten¬ tial insect destroying Graptophyllum pictum crop was caried out at the Entomological laboratory duing November 1997 to May 1998 The objective of the research was to evaluate the effect of azadirachtin A on some biological aspects of D. polibete. The formulation was obtained from FID Parry Ltd. (India), containing 1% azadirachtin A. The concentration recommended was 2-4 ml of formulation It of water or equal to 20-40 ppm of azadirachtin A The insects tested were obtained by reaing them in a screen house. Research was arranged in a completely randomized design, and randomized block design (for ovicidal). 6 treatments and 4-6 eplications. The treaments were concentrations of azadirachtin A (I) 80 ppm (2) 40 ppm (3) 20 ppm, (4) 10 ppm. (S) 5 ppm and (6) 0 ppm. Research consisted of three activities, i.e. effect of neem extract on (1) insect mortality and the survival rate. (2) as antifeedant, and (3) asovicidaon the insect. Results showed that azadirachtin A killed the insect slowly, it needed 3-10 days. Azadirachtin A acted as a growth inhibitor shown by the fact that at 5 and 10 ppm azadirachtin A, some pupae became malformed adults and other pupae died in a failed molt attempt Azadirachtin functioned as an antifeedant on some adult insects where the pupae were malformed and died on antifeedant and inhibit about 40% of feeding deference. Azadirachtin A also acted as an ovicidal inhibited about 50% egg-hatching.
