Dacus dorsalis Hendel and Dacus zonatus (Saunders) ) ผู้เขียน: นายสุธรรม อารีกุล, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractComparative toxicity tests of ten insecticides were made against Dacus zonutus (Saunders) and Dacus dorsalis Hendel (Tephritidae, Diptera). In the feeding method, it reveals that the susceptibility of both species to trichlorfon and malathion was increased as the age of adult flies increased from 1,7,14,21 and 24 days respectively. Results from this study also showed that D. zonatus was 2.5 and 1.5 times respectively higher resistant to trichlorfon and malathion than D. dorsalis. The species also demonstrated higher tolerance to the following insecticides when they were tested at two days old age through the following methods: isoprocarb, methyl parathion, and BHC by vaccuum dusting; DDT, trichlorfon, carbaryl, and malathion by toxicity deposit; and malathion by topical application. However, the results were reversed when the topical application was employed in testing with trichlorfon, carbaryl, methomyl, dimethoate, and cypermethyl. The insects showed no significant difference in their susceptibility when trichlorfon, malathion, and cabaryl were injected directly into their blood stream. Malathion and trichlorfon are normally recommended for bait sprays in combination with an attractant such as the yeast protein hydrolysate. Since D. zonatus is comparatively higher resistant to both insecticides, it may need higher dosages for the bait sprays in the field in order to obtain satisfactory results of simultaneous controls of both species. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : The Economic Importance of the Fruit Fly, Dacus zonatus (Saunders) in Thailand) ผู้เขียน: Saen Tigvatananont, นายสุธรรม อารีกุล, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractEgg, larval, pupal and adult stages of the fruit fly, Dacus zonatus (Saunders), lasted on the averages 33.13 hours, and 7.40,11.00 and 71.00 days respectively when reared on a semiartificial diet which consisted of banana pulp, corn flour, Brewer's yeast, sugar, tissue paper, sodium benzoate, hydrochloric acid, and water. They were comparatively close to the oriental fruit fly, Dacus dorsalis Hendel, which lasted on the averages 36.13 hours, and 8.20, 11.50 and 88.40 days respectively when reared on the same diet. Riped fits sampling from trees of Singapore almond (Terminalia catappa Linn.), ma-kok-nam (Elaeocapus madopetalus Pierre), guava (Psidium guajava Linn.), and rose apple (Eugenia javanica Lamk.) in Bangkok area in july, August, December, and February showed the infestation of D. zonatus in association with D. dorsalis. Th'e ratios of adult flies of D. zonatus and D. dorsalis emerged from these fruits were 1 : 1.09, 1 : 0.07,l : 2.88 and I : 1.33 respectively. With its wide range of host and distribution, D. zonatus has become one of the major economic important pests of fruits, comparable to D. dorsalis, in this country. |
