 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Plant Crude-Extracts on the Cattle Tick (Boophilus microplus) Insecticidal Action I) ผู้เขียน:ดร.ณรงค์ จึงสมานญาติ, รองศาสตราจารย์, ดร.สุรัตน์วดี จิวะจินดา , นายวีระพล จันทร์สวรรค์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe ethanol crude-extracts from five plants species; Acanthus ebracteatus Vahl., Acorus calamus L., Annona squamosa L., Luffa acutangula Roxb., and Stemona collinsae Craib. having high larvicidal activity on cattle ticks, were in vitro bioassayed with the insecticidal activity on adult tick by dipping method. The 10% of ethanol crude-extract of Annona squamosa seeds had high insecticidal action. The corrected mortality of adult ticks after dipping at 48h were 100%, 100% and 92.50% in 10%, 5% and 2% of its crude-extract respectively. The 10% of ethanol crude-extracts of L. acutangula seeds had moderate toxicity. The crude-extract of A. calamus rhizomes and S. Collinsae roots showed low insecticidal activity, and the crude-extract from A. ebracteatus and A. squamosa leaves had very low insecticidal activity. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Tamarindus indicus L. Against the Boophilus microplus) ผู้เขียน:ดร.ณรงค์ จึงสมานญาติ, รองศาสตราจารย์, นายวีระพล จันทร์สวรรค์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe crude-extract of Tamarindus indicus L. with water and 10% ethanol in water were tested the acaricidal activity on the engorged female cattle tick (Boophilus microplus) by dipping method. The mature tamarind fruits taking off the seeds were extracted by water or 10% ethanol in the ratio of 1:2 and 1:5 W/V for 7 days. The corrected mortality of the ticks were observed after dipping at 24 h, 48 h and 7 days. The mean of corrected mortality of ticks of these 4 crude-extracts of tamarind fruits were 56-70 %, 70-89% and 77-99% by no statistically significant different after dipping at 24 h, 48 h and 7 days, respectively. The organic acids in tamarind fruits (oxalic, malic, succinic, citric and tartaric acids) were also bioassayed the acaricidal activity by dipping method. The oxalic acid of 0.5% and 1% concentration exhibited the highest acute acaricidal activity (56% and 62% mortality of ticks at 24 h after dipping, respectively). The tartaric acid 1% concentration showed the highest delayed acaricidal activity (73% mortality of ticks at 7 days after dipping). The mixture of 0.5% of oxalic acid with 0.5% of malic, succinic, citric and tartaric acids by concentration of 1:1 V/V were tested the acaricidal activity. The acaricidal activity of these acid mixtures were not more stronger than those of each individual acid. Both of crude-extract of tamarind fruits and their organic acids caused the patchy hemorrhagic swelling on the skin of ticks after dipping at 15 min. This indicates that the crude-extract of tamarind fruits by water or 10% ethanol is possibly use in practical for controlling the tropical cattle tick. The active substances are their organic acids, especially oxalic and tartaric acids. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Acaricidal Effect of Plant Crude-extracts on Tropical Cattle Ticks (Boophilus microplus)) ผู้เขียน:ดร.ณรงค์ จึงสมานญาติ, รองศาสตราจารย์, ดร.สุรัตน์วดี จิวะจินดา, นายวีระพล จันทร์สวรรค์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe 171 ethanol crude-extracts from 151 plant species were in vitro tested for acaricidal activity on adult tropical cattle ticks by the dipping method. The 10% solution of crude-extract of Calotropis gigantea R. Br. And Streblus asper Lour. Exhibited high acaricidal activity (92% and 100% corrected mortality of ticks 48 h after dipping). Relatively high acaricidal activity (71-85% mortality) was found in the crude-extracts of Aganorcrion polymorphum P.S., Datura metel L. and Rhinacanthus nasutus Kurz. Acaticidal activity of some crude-extracts was observed 5 days after dipping, Which might indicate delayed toxicity. The high delayed acaricidal activity ( 86-100% non laying ) was occurred in Alpinia officinarum Hance, Annona muricata Llk Calotropis procera R.Br., Michelia champaca L;, Pachyrrhisus erosus L., Plumbago zeylandica L, Polyscias balfouriana B., Premna latifolia Roxb., Thunbergia erecta T. Anders., and Thunbergia laurifolia Lindl.. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Pathological Studies of Marek's Disease in Laying Hens) ผู้เขียน:เจริญ ทองมา, ภิรมย์ ศรีวรนาถ, วีระพล จันทร์สวรรค์ สื่อสิ่งพิมพ์:pdf AbstractThe results of pathological studies including clinical signs and mortality rate of Marek's disease in laying hens were as follo~vs, the clinical signs of the disease in laying hens were categorised into 2 forms, one had clinical signs of depression and sudden death and some were found dead without clinical signs- The other group ].lad clinical signs of depression, lameness and emaciation and some showed signs of posterior paralysis, drooping wings and alopecia. The mortality rate in this outbreak was 48.5%. Seventeen chickens with nervous signs randomly selected for post-mortem examination showed the gross findings of nerve enlargement and tumourous masses in visceral organs, muscles and skin. Microscopic findings included pleomorphic lymphoid infiltration in nerves and visceral organs and lymphocytic perivascular cuffing in brain. These gross and microscopic findings were identical to classical form of Marek's disease. The chicken with history of sudden death had no gross and microscopic findings in nerves and brain but only tumourous masses containing pleomorphic lymphoid cells could be observed in visceral organs, muscles and skin. This form of the disease was characterised as acute form of Marek's disease. Methyl green-pyronin staining was very helpful guide for differential diagnosis of acute form of Marek's disease and lymphoid leukosis. Ocular form of the disease was not observed in this study. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Bioassay Techniques of Insecticidal Plant - Extracts on Tropical Cattle Ticks (Boophilus microplus)) ผู้เขียน:ดร.ณรงค์ จึงสมานญาติ, รองศาสตราจารย์, นายวีระพล จันทร์สวรรค์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe engorge female of tropical cattle ticks survived in vitro more than 72h and began laying at 70-75h after taking from cattles. The larvae were hatches 14-23 days after laying. The unfed larvae survived more than 2 months in humid bottle. The leg contact method was used for larvicidal bioassay. The larvae were left to contact with the dry film of plant-extract. The mortality of larvae in empty, evaporated ethanol-and ethyl acetate- coated bottles as control were considerably low and no significant difference were found among them. In insecticidal bioassay of adult ticks, both body dip0ing and leg contact methods could be applied. The dipping method was rapid and easy procedure for screening bioassay. The leg contact methods was used for bioassay in the fractionation of compounds dissolved in non polar organic solvents. The mortality of engorge female ticks was very low at 48 h after dipping with water, methanol, ethanol, acetone and 2% polyoxyethylene sorbitan mono – oleate. After dipping with ethyl acetate and toluene the mortality were high. The survival checks of larvae was observed on its leg movement after exposing to fresh air. The treated engorge female tick was observed in its leg and body movement after exposing to warm-air, 100w lamp’s light sunshine and direct press to the body. The non survival ticks were confirmed by its non laying. This study demonstrated that the cattle ticks can be bioaassayed for larvicidal and insecticidal activities in vitro before further application in vivo |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Aspirin and Sucrose on Vase Life of Cut Ross) ผู้เขียน:ดร.ณรงค์ จึงสมานญาติ, รองศาสตราจารย์, ดร.สุรัตน์วดี จิวะจินดา, นายวีระพล จันทร์สวรรค์, รองศาสตราจารย์, Udom Kaewsuwan, Panas Buranasilpin สื่อสิ่งพิมพ์:pdf AbstractChristian Dior cut roses were vased in holding solutions containing 5% sucrose together with 100, 200, 300, 400, and 500 ppm aspirin at room temperature (28.4 C and 69.1% RH). The results showed that cut roses in the holding solution containing 300 ppm aspirin +5% sucrose had the longest vase life of 7.42 days while those in tap water had vase life of 3.83 days. Cu roses in the holding solution had less blueing and bent neck, larger size of blooming, higher rate of water uptake and weight increase than those in tap water. Cut roses in the holding solution containing only 5% sucrose with pH adjustment to 4.0 equalizing to that of the holding solution containing 300 ppm aspirin +5% sucrose, their vase life was shorter than those kept in the holding solution. This suggests that the role of aspirin in extending the vase life of cut roses is a germicide aside from lowering pH of the holding solution. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effective Plant Crude-Extracts on the Tick (Boophilus Miscroplus) I. Larvicidal Action) ผู้เขียน:ดร.ณรงค์ จึงสมานญาติ, รองศาสตราจารย์, ดร.สุรัตน์วดี จิวะจินดา, นายวีระพล จันทร์สวรรค์, รองศาสตราจารย์, Udom Kaewsuwan, Panas Buranasilpin สื่อสิ่งพิมพ์:pdf AbstractForty four species of plants were extracted with ethanol. The larvaes of the tick (Boophilus microplus) were left to contact with the coating of 1.14 mg/cm2 of crude-extract in bottle. Five crude-extracts of these plants having larvicidal action (90-100% mortality rate) are as follow; Acanthus ebracteatus Vahl., Acrorus calamus L., Annona squamosa L., Luffa acutangula Roxb., and Stemona collinsae Craib. The insecticidal action of these crude-extracts on the adult tick is being test. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Acaricidal Activity of Peel Oil of Citrus spp. On Boophilus microplus) ผู้เขียน:Narong Chungsamarnyary, นายวีระพล จันทร์สวรรค์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractPeel oil from three varieties of Citrus maxima Merr. (pomelo): Khaao-phuaing (immature fruit), Thong-dee (immature and mature fruits) and Khaao-nam-phueng (mature fruits); Citrus reticulata Blanco., Citrus suncris Linn., Citrus sinensis Linn. And Citrus hystrix DC. were collected by mechanical pressing. These peel oil and the d-limonene substance were diluted with 95% ethanol into 1:5, 1:10 and 1:5 (V/V) and tested the acaricidal activity on the engorged female cattle tick (Boophilus microplus) by dipping method. The acaricidal activity on the tick larvae was tested with these oil and d-limonene dilution of 1:10 and 1:15 (V/V). The peel oil of C.reticulata and C.maxima variety thong-dee (immature and mature fruits) showed high acaricidal activity at the concentration of 1:10 (V/V) on engorged female ticks. These peel oil activity were 2 times thigher than that of d-limonene. The peel oil concentration 1:10 of C.sinensis and C.maxima (mature) exhibited high larvicidal activity, while the oil of C.hystrix, C.reticulata, C.suncris and C.maxima (immature fruits) showed relatively high larvicidal activity. Their larvicidal activity were 1.5 times stronger than d-limonene. The peel oil of the other citrus spp. Exhibited weaker acaricidal activity. This indicated that the peel oil from the citrus fruits could be directly applied to control the cattle tick. The waste of the over fruiting immature pomelo, would be of potential usage as a biocontrol substance. |
