Feeding-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 کاملProbing stimulants from the rice plant towards the smaller brown planthopper, Laodelphax striatellus (FALLEN) (Homoptera: Delphacidae).
When adult males of the smaller brown planthopper, Laodelphax striatellus were fed on 2% crude rice (leaf and stem) extract containing 15% sucrose there were characteristic stylet sheaths deposited on parafilm membrane. Further bioassays with the butanol-soluble fr. of the extract revealed that it is highly effective for the insects. When the butanol fr. was charged on an ODS open column and el...
متن کاملNutrient uptake of rice roots in response to infestation of Nilaparvata lugens (Stål) (Homoptera: Delphacidae).
This study investigated the uptake of three macronutrients, including nitrogen (N), phosphorus (P), and potassium (K), by rice roots in response to different infestation levels of Nilaparvata lugens (Stål) (Homoptera: Delphacidae). Hydroponics experiments were conducted on the rice variety 'Zhendao 2' (moderately resistant to Tryporyza incertulas, Lepidoptera: Pyralidae) and the variety 'Xiushu...
متن کاملEffects of temperature on mate location in the planthopper, Nilaparvata lugens (Homoptera: Delphacidae).
The planthopper, Nilaparvata lugens Stål (Homoptera: Delphacidae), uses acoustic signals generated by abdominal vibration and transmitted through rice (Oryza sativa L.) plants to locate mates. The influence of temperature (20, 28, and 32°C) on abdominal vibration patterns of individual females and males, proportion of mated females, and responsivity of male to female vibrational signals was in...
