Phylogenetic position of the yeast-like symbiotes of Tagosodes orizicolus (Homoptera: Delphacidae) based on 18S ribosomal DNA partial sequences

Revista de Biología Tropical, 2004
Tagosodes orizicolus Muir (Homoptera: Delphacidae), the endemic delphacid species of tropical America carries yeast-like symbiotes (YLS) in the abdominal fat bodies and the ovarial tissues, like other rice planthoppers of Asia.

EGG AND NYMPHAL PARASITES OF RICE LEAFHOPPERS AND PLANTHOPPERS. A RESULT OF FIELD STUDIES IN TAIWAN IN 1979 (PART 1)

, 1981
Results of field studies on egg parasites of rice leaf- and planthoppers made in Taiwan in 1979 are presented. Anagrus optabilis was reared from the eggs of Sogatella furcifera, Paracentrobia andoi and Anagrus optabilis from Nilaparvata lu-gem, Anagrus ...

Geographic and research center origins of rice resistance to Asian planthoppers and leafhoppers: implications for rice breeding and gene deployment

This study examines aspects of virulence to resistant rice varieties among planthoppers and leafhoppers. Using a series of resistant varieties, brown planthopper, Nilaparvata lugens, virulence was assessed in seedlings and early-tillering plants at seven

Changes in insecticide resistance and host range performance of planthoppers artificially selected to feed on resistant rice

Host plant resistance has received considerable attention for the management of insect herbivores on crop plants. However, resistance is threatened by the rapid adaptation of target herbivores towards virulence (the ability to survive, develop and damage

Forecasting model of population fluctuation and occurrence of brown planthoppers

, 2014
褐飛蝨為台灣最重要水稻害蟲之一，如防治不當則導致水稻品質及產量降低，造成莫大的損失。台灣每年亦會遭受海外蟲源之遷入，每年遷入時間及族群大小不一，且蟲害可長距離遷移，遷入台灣之害蟲來源區域甚廣，再加上大環境氣候異常，害蟲族群之變化更劇烈，有待長期監測，以掌握族群之變動。因此配合長期田間害蟲族群發生動態，利用時間序列分析方法，建立門檻自相關模式，並結合相關重要因子(例如:水稻移植後之天數)當作解釋變數，來發展提早偵測害蟲之大發生，為早期預警、適時施藥防治、達到水稻安全生產目的之重要目標。Brown ...
