 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Efficacy of Cypermethrin, Neem Extract and Bacillus thuringiensis for Controlling Insect Pests of Vegetable Soybean) ผู้เขียน:Md. Abdullah, Ouab Sarnthoy, Somchai Isichaikul, ดร.ศิริพรรณ ตันตาคม, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractField experiments were conducted during dry and wet seasons (1999-2000) at Kamphaeng Saen Campus of Kasetsart University, Nakhon Pathom, Thailand to evaluate the efficacy of cypermethrin 10 EC, neem extract (Azadirachtin 0.1%) and Bacillus thuringiensis var. kurstaki (53,000 SU/mg) in controlling the major insect pests of vegetable soybean. Melanagromyza sojae, Spodoptera litura, Spodoptera exigua, Helicoverpa armigera, Lamprosema indicata, Etiella zinckenella and Bemisia tabaci were the most abundant species in both seasons. Insecticides were sprayed at 10 days interval until harvest. Cypermethrin showed significantly better control among the treatments. Neem extract moderately suppressed the insect pests with statistically significant efficacy over the control. B. thuringiensis var. kurstaki showed less efficacy than neem extract but exhibited statistically significant efficacy over the control in most cases. Highest yield was recorded in cypermethrin treated plot (9.83 t/ha) followed by neem extract (8.39 t/h), B. thuringiensis var. kurstaki (7.98 t/ha) and control (6.22 t/ha) in dry season whereas yields were 5.83, 4.83, 4.0 and 2.83 t/ha for cypermethrin, neem extract, B. thuringiensis var. kurstaki and control in wet season, respectively. Additionally, Menochilus sexmaculatus and spider were found less in cypermethrin treated plots whereas in other treatments they were significantly higher in number. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Synergistic Effects of Sesame Oil with Cypermethrin on the Survival and Detoxification Enzyme Activity of Plutella xylostella L. Larvae) ผู้เขียน:ดร.สุรพล วิเศษสรรค์, รองศาสตราจารย์, John Milne, มัณฑนา มิลน์, Pintip Kanasutar สื่อสิ่งพิมพ์:pdf AbstractTwo types of insect-toxicity tests, (1) contact and (2) no-choice leaf dipping test, were conducted using the insecticide cypermethrin without piperonyl butoxide (PB), cypermethrin with PB and cypermethrin with sesame oil against the 2nd –3rd instar larvae of Plutella xylostella L. Sesame oil showed good synergism with cypermethrin yielding synergistic ratios (SR) that ranged from 1.54 – 6.33 in the contact method and 2.04-5.88 in the no-choice leaf dipping method and were comparable to using PB, which showed SR’s of 6.33 and 6.71, respectively. Both PB and sesame oil mixed together with cypermethrin inhibited monooxygenase activity by approximately two-third but induced glutathione–S-transferase ca. 2-3 folds in both methods. The synergists had no effect on esterase activity (CF ca. 1.2). Residues of cypermethrin in the larvae increased by 1.29 – 2.57 folds in the treatments with added sesame oil compared to a 2.86 fold increase when PB was added, using the contact method. The no choice leaf dipping method revealed that cypermethrin residue levels increased by 2.82 – 6.91 fold with added sesame oil and 8.27 fold with added PB. This indicated that both PB and sesame oil played the same role in the inhibition of an enzyme, possibly monooxygenase. Field trials with Chinese kale showed the same trends that were evident in the laboratory work. The addition of sesame oil to the insecticide reduced the larval population by 70-80 percent while the addition of PB reduced the larval population by up to 88 percent in the kale crop. Monooxygenase activities of insect larvae collected in the field from kale sprayed with cypermethrin plus synergist (sesame oil or PB) were lower than those from kale treated with insecticide alone. The results in terms of synergism and changes in enzyme metabolism were discussed. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Cypermethrin Insecticide Residues in Vegetable Soybean, Glycine max (L.) Merrill, at Different Days of Pre-harvest Interval) ผู้เขียน:Md. Abdullah, Ouab Sarnthoy, ดร.สุรัตน์วดี จิวะจินดา สื่อสิ่งพิมพ์:pdf AbstractThe experiments were conducted to investigate cypermethrin insecticide residues in vegetable soybean at different days of pre-harvest interval for two growing seasons. Soybean pods were collected at 0, 1, 3, 5 and 10 days after last application with cypermethrin. Residues were extracted from pods and determined using gas liquid chromatography with an electron capture detector. Cypermethrin when applied at the rate of 100 g ai/ha using a knapsack sprayer showed a mean residue level of 0.71 and 0.52 mg/kg at 0 and 1 day, respectively, in dry season (December- February) whereas the residues were 1.62 and 1.17 mg/ kg at 0 and 1 day, respectively, in early wet season (April-June). A pre-harvest interval of 3 days was found safe (0.42 mg/kg) for consumers in dry season whereas early wet st season soybean exhibited residue level of 0.48 mg/kg at 10 day which fell below maximum residue limit of 0.5 mg/kg as prescribed by Food and Agriculture Organization/World Health Organization. Therefore, a pre-harvest interval of 10 days should be considered for cypermethrin residues in vegetable soybean to avoid any health risk of consumers. The dissipation rates of cypermethrin on soybean pods were more or less similar at the same days for both seasons which was 70% (based on 0 day) at 10 days. |
