Abstract

Attack of Aphis gossypii is one of constraints in cultivating of patchouli plant. An experiment with the purpose to examine the effectiveness of botanical insecticides to A. gossypii on patchouli plant. The experiment was carried out in Research Station of Indonesian Spice and Medicinal Crops Research Institute, at Cicurug, Sukabumi from June to October 2011. The experiment was arranged in a Randomized Block Design, nine treatments and three replications. The treatments were mixing of neem oil + soap nuts, neem oil + clove oil, neem oil + citronellal oil, neem oil + clove oil + citronellal oil, citronellal oil, clove oil, neem extract, carbosulfan, and control. Patchouli plants were planted with spacing of 40 cm x 60 cm. The number of plant population plot-1 was 25 plants and the number of sample plot-1 for observation was five plants. Sampling of observed plants was conducted diagonally. Observation was carried out by counting population of A. gossypii on one shoot. Application of insecticides was conducted one day after the first observation. Interval of application was every week, conducted eight times. Other parameters observed were plant height and production of patchouli. Results showed that all treatments of botanical insecticides were effective to decrease of A. gossypii population. The most effective treatment was that of neem extract with the value of  efficacy was more than 80% occurred at seven assessments. Plant high between treatment is not significant different.

Abstract

Brown planthopper is still a major problem in rice. Control using botanical insecticides is considered less effective, since its persistence in rice plantation is short. Research on the persistence of botanical insecticide residues of pyrethrum and neem in rice has been conducted in green house of Entomology, Indonesian Spices and Medicinal Crops Research Institute, Bogor from January to December 2016. The research was aimed to determine the persistence of botanical insecticide residue on rice by testing it to brown planthopper mortality. The study was arranged in complete randomized design with six treatments and four replications. The treatment consisted of two pyrethrum formulas (EC); two neem formulas (EC); positive controls of synthetic insecticides (a.i. carbosulfan) and negative control (water). The method used was Leaf Residue Method, by spraying the formula into one month-old rice plants, then 10 brown planthopper nymphs of forth instar were introduced into each plant in the first, second, third and fourth day after spraying.  The planthopper mortality was observed in the first, third, sixth, 24th and 48th hours after introduction. The residuals of all insecticides tested were still affecting the  mortality of brown planthopper until the fourth day after spraying, although the effectiveness decreased by the time. The average mortality on the first day introduction after spraying ranged between 53-73 % and in the fourth day after spraying was 18-25 %.

Abstract

Brown plant hopper (Nilaparvata lugens Stal) is the main pest on rice cultivation.  Synthetic insecticides application had negative impact to the human health and environment. The research objective was aimed to examine the effectiveness of botanical (pyrethrum and neem) and bio-insecticides (Beauveria bassiana/Bb and Metarhizium anisopliae/Ma) against brown plant hopper. Research was conducted at Entomology Laboratory of Indonesian Spices and Medicinal Crops Research Institute, Bogor in 2017. Trial consisted of two activities: the effectiveness of botanical and bio-insecticides to brown plant hopper mortality and horizontal transmission of bio-insecticides on brown plant hoppers. Botanical pesticide tested was (1) pyrethrum I (5 ml.l-1 water ), (2) pyrethrum II (5 ml.l-1 water), (3) neem I (20 ml.l-1 water), (4) neem II (20 ml.l-1 water), (5) synthetic insecticide (2 ml.l-1 water) and (6) control.  Bio-insecticide treatments were (1) Bb (spraying, 2.5 ml/plant), (2) Bb (granule, 5 g/pot), (3) Ma (spraying, 2.5 ml/plant), (4) Ma (granule, 5 g/ pot) and (5) control.  Treatments of horizontal transmission was the ratio of infected : healthy brown plant hopper 1 : 10; 2 : 10; 3 : 10 and 4 : 10. Botanical insecticides were prospective to suppressing brown plant hopper population of 85-87 % (pyrethrum) and   60-70 % (neem).   B.  bassiana was able  to   suppress   brown   plant     hopper population (18.2%), better than   M. anisopliae (5.6 %). Biological insecticide application by contact (spraying) was better than applied in granules form.  Botanical insecticide application showed no horizontal transmission from infected to healthy insect. Botanical insecticide (pyrethrum and neem) was more prospective than bio-insecticide (B. bassiana and M. anisopliae) in controlling brown plant hopper.
