 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Thai Plant Extracts on the Oriental Fruit Fly I. Toxicity Test.) ผู้เขียน: Effect of Thai Plant Extracts on the Oriental Fruit Fly,  นายสุธรรม อารีกุล, ศาสตราจารย์ , Prateungsri Sinchaisri, Saen Tigvatananon สื่อสิ่งพิมพ์:pdf AbstractExtracts of plants materials were prepared by employing three procedures, namely the cold-rolling, the soxhlet extraction and the water distillation methods. Three hundred and three extracts from 165 species of plants were tested against two days old adult Oriental fruit flies using the mist spray at the rate of one gram equivalent each. Extracts from plant parts which demonstrated moderately high to high toxicities were rhizomes of Alpinia officinarium Hance, fruit skin of Anona squamosa Linn., whole plants of Euphorbia tirucalli Linn., leaves of Nicotiana tabacum Linn., leaves and branches of Azadirachta indica var. siamensis, Veleton, fruit skin of Citrus sinensis Osb., and roots of Stemona tuberose Lour. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Thai Plant Extracts on the Oriental Fruit Fly1 III. Attractancy Test) ผู้เขียน:S. Tudsri, B.R. Watkin, A.C.P. Chu, B.J. Forde สื่อสิ่งพิมพ์:pdf AbstractAttractive potency tests were made on 487 extracts of 231 kinds of plants among which 205 were identified and 26 were unknown species. The rates of competitive attractiveness were determind from the number of the Oriental fruit fly, Dacus dorsalis Hendel, which entered at 1, 6, 12 and 24 hours in to traps in an olfactometer in which one gm equivalent of each plant extract was placed in each trap. Eight day old flies of both sexes were used in this experiment. Plants among which demonstrated highly attractive to the test flies were Crinum asiaticum Linn., Dieffenbachia requine Schott., Nerium indicum Mill., Ocimum sactum Linn., Thitonia diversifolia Gray, and Vallaris graba Ktze. Plants among which their extracts exhibited moderate attractive potency were Bixa orellana Linn., Curcuma comosa Roxb., Cymbopogon flexuosus Nee & Stend., Datura metel Linn., Elsholtzia blanda Benth., Holmoskioldia sanguine Retz., Homalomena sp., Lantana camara Linn., Melia azederach Linn., Momorica charantia Linn., Monstera deliciosa Liebm., Murraya paniculate Jack, Musa sapientum Linn., Nerium indicum Mill., Ocimum gratissimum Linn., Poinciana pulcherima Sw., Quisquallis indica Linn., Ruellia tuberose Linn., Terminalia catappa Linn., Thysanolaena maxima Kty., and Vallaris glaba Ktze. Among unidentified plants, Chang-Kan, En-Luang, and Kha-pa were included in this case. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Thai Plant Extracts on the Oriental Fruit Fly II. Repellency Test.) ผู้เขียน:S. Tudsri, B.R. Watkin, A.C.P. Chu, B.J. Forde สื่อสิ่งพิมพ์:pdf AbstractThe repellent potency of plant extracts to the Oriental fruit fly, Dacus dorsalis, was determined on the basis of the rate of oviposition on cups containing 20% of citrus juice and coated outside with a mist spray of one gram equivalent of each plant extract per cup. One hundred and thirty extracts from 110 kinds of plants among which 97 were known species and 13 unknown were tested. Fifteen day old female flies which were known to lay high numbers of eggs were used in this experiment. Plant extracts which exhibited high repellency to the oviposition of the female flies were obtained from Azadirachta indica var. siamensis Veleton, Bixa orellana Linn., Citrus hystrix D.C., Cucumis melo Linn., Cymbopogon citrates Stapf., Hedychium coccineum var. angustifolium Roxb., Heliotropium indicum R. Br., Homalomena sp., Ocimum gratissimum Linn., Ricinus communis Linn., and Ternstroemia japonica Thunb. Among the unidentified species, they included En-Luang and Phra-Taba. Moderate levels of repellency were obtained from extracts of Allium sativum Linn., Melodorum fruticosum Lour, and Meha-Kamlang. Mild repellent to the oviposition of the flies was exhibited by plant part extracts of the following species: Acharas aspota Linn., Alpinia siamensis Schum., Andrographis paniculate Wall. Ex Nees, Anona squamosa Linn., Anthemis nobilis Linn, Bougainvillea spectabilis Willd., Cinnamomum siamense Craib., Cinnamomum zeylanicum Linn., Curcuma comosa Roxb., Curcuma longa Linn. ( = C. domestica Veleton), Curcuma zedoaria Roxae, Elholtzia blanda Benth., Eupatorium adenophorum Spreng., Jatropha curcas Linn., Jatropha gossypifolia Linn., Litsea cubeba Pers., Mentha cordifolia Opiz., Momordica charantia Linn., Myristica fragrans Linn., Piper sarmentosum R. ex H., Portulaca pilosa Linn., Quisqualis indica Linn., Stemona tuberose Lour., and Tinospora crispa Miers. Of the unidentified species, they included Gai-Khan, Kan-Tha-Mala, Lai-Ma, Ma-Haw, and Maurakot. |
