Genome sequence of the small brown planthopper, Laodelphax striatellus
Background Laodelphax striatellus Fallén (Hemiptera: Delphacidae) is one of the most destructive rice pests. L. striatellus is different from 2 other rice planthoppers with a released genome sequence, Sogatella furcifera and Nilaparvata lugens, in many biological characteristics, such as host range, dispersal capacity, and vectoring plant viruses. Deciphering the genome of L. striatellus will f...
متن کاملTake-Off Time of the First Generation of the Overwintering Small Brown Planthopper, Laodelphax striatellus in the Temperate Zone in East Asia
Overseas migration of the small brown planthopper, Laodelphax striatellus (Fallén), occurs during the winter wheat harvest season in East Asia. Knowing the take-off time of emigrating L. striatellus is crucial for predicting such migrations with a simulation technique because winds, carriers of migratory insects, change continuously. Several methods were used in China and Japan from late May to...
متن کاملFeeding-induced interactions between Nilaparvata lugens and Laodelphax striatellus (Hemiptera: Delphacidae): effects on feeding behavior and honeydew excretion.
Using electrical penetration graph, salivary flange, and honeydew measurement, this study investigated the effects of feeding-induced intra- and interspecific interactions on feeding behavior and honeydew excretion of brown planthopper (Nilaparvata lugens) compared with small brown planthopper (Laodelphax striatellus). Results showed that many measures of feeding behavior were affected by feedi...
متن کاملTRANSGENIC PLANTS AND INSECTS Field Assessment of the Effects of Transgenic Rice Expressing a Fused Gene of cry1Ab and cry1Ac from Bacillus thuringiensis Berliner on Nontarget Planthopper and Leafhopper Populations
In 2003 and 2004, Þeld studies were conducted at three sites in Zhejiang Province in China to assess the impacts ofBacillus thuringiensis(Bt)Berliner riceexpressing a fusedgeneof cry1Ab and cry1Ac on nontarget planthoppers and leafhoppers. Populations in Bt plots were sampled with yellow sticky card traps, Malaise traps, and a vacuum-suction machine, and compared with samples from non-Bt contro...
متن کاملCross-resistance and possible mechanisms of chlorpyrifos resistance in Laodelphax striatellus (Fallén).
BACKGROUND Laodelphax striatellus (Fallén) is a major pest of cultivated rice and is commonly controlled in China with the organophosphate insecticides. To develop a better resistance management strategy, a chlorpyrifos-resistant strain of L. striatellus was selected in the laboratory, and its cross-resistance to other insecticides and possible mechanisms of the chlorpyrifos resistance were inv...
