Feeding-induced interactions between two rice planthoppers, Nilaparvata lugens and Sogatella furcifera (Hemiptera: Delphacidae): effects on feeding and honeydew excretion.
A series of laboratory experiments was conducted using electrical penetration graph, salivary flange, and honeydew measurement to study the effects of feeding-induced intra- and interspecific interactions on feeding behavior and honeydew excretion between planthoppers Nilaparvata lugens (Stål) and Sogatela furcifera (Horváth). Feeding-induced intra- and interspecific interactions affected many ...
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 کاملSelection of global Metarhizium isolates for the control of the rice pest Nilaparvata lugens (Homoptera: Delphacidae).
BACKGROUND This study was initiated to search for fungal candidates for microbial control of brown planthopper (BPH) Nilaparvata lugens Stål, to which little attention has been paid in the past two decades. RESULTS Thirty-five isolates of Metarhizium anisopliae (Metschnikoff) Sorokin and M. flavoviride Gams & Rozsypal from different host insects worldwide were bioassayed for their lethal effe...
متن کاملAgro-ecological zoning of brown planthopper [Nilaparvata lugens (Stal)] incidence on rice (Oryza sativa L.)
Multiple linear regression models (pest-weather models) were developed between monthly mean brown planthopper (BPH), Nilaparvata lugens light trap catches and monthly mean values of minimum temperature (Tmin), maximum temperature (Tmax), morning relative humidity (RH 1 ) and evening relative humidity (RH 2 ) observed at Maruteru, Andhra Pradesh during 2000-2007 kharif seasons. Comparison betwee...
متن کاملLife-table analysis of the performance of Nilaparvata lugens (Hemiptera: Delphacidae) on two wild rice species.
Life tables of the planthopper Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) on two wild rice species, Oryza officinalis Wall, ex Watt. and Oryza rufipogon Griff., and on 'Taichung Native 1' (O. sativa indica TN1) were studied at 27 degrees C in the laboratory. The raw data were analyzed based on the age-stage, two-sex life table to take both sexes and the variable developmental rate among...
