چکیده
Brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is an economically important insect pest of rice crop worldwide including Pakistan. The use chemicals insecticides to control the BPH population has been considered effective strategy. However, long-term and intensive resulted in resistance against this pest. In study, six recommended were tested over period 2015-2019 determine susceptibility level. From 2015-19, was reduced all insecticides. Increasing trend LC50 values recorded fipronil (18.23-35.11 mg/L), imidacloprid (64.22-128.8 buprofezin (185.01-315.0 chlorantranilipyrole (199.2-263.3 pymetrozine (248.2-315.5 nitenpyram (21.07-34.3 mg/L) respectively from 2015 2019. Correlation coefficient indicated a significant relation (P < 0.05) between fipronil, imidacloprid, buprofezin. study will be helpful for management strategies prevent development

An adenylyl cyclase like-9 gene (NlAC9) influences growth and fecundity in the brown planthopper, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae)
The cAMP/PKA intracellular signaling pathway is launched by adenylyl cyclase (AC) conversion of adenosine triphosphate (ATP) to 3', 5'-cyclic AMP (cAMP) and cAMP-dependent activation of PKA. Although this pathway is very well known in insect physiology, there is little to no information on it in some very small pest insects, such as the brown planthopper (BPH), Nilaparvata lugens Stål. BPH is a...

The brown planthopper (BPH), Nilaparvata lugens, sugar transporter gene 6 (Nlst6) is a facilitative glucose/fructose transporter (often called a passive carrier) expressed in midgut that mediates sugar transport from the midgut lumen to hemolymph. The influence of down regulating expression of sugar transporter genes on insect growth, development, and fecundity is unknown. Nonetheless, it is re...

BACKGROUND In recent years, outbreaks of the brown planthopper, Nilaparvata lugens (Stål), have occurred more frequently in China. The objective of this study was to determine the susceptibility of N. lugens to neonicotinoids and other insecticides in major rice production areas in China. RESULTS Results indicated that substantial variations in the susceptibility to different insecticides exi...

BACKGROUND The brown planthopper (BPH), Nilaparvata lugens Stål, is a major rice pest in many parts of Asia. Neonicotinoids such as imidacloprid and dinotefuran are widely used for control of this pest, and resistance to these insecticides has developed in recent years. This pest has also been widely exposed to triazophos and fenvalerate, although these insecticides are not used for the control...

A new virus, belonging to the reovirus group, was found in an apparently healthy colony of the brown planthopper, Nilaparvata lugens, and was referred to as the Nilaparvata lugens reovirus (NLRV). The virus was found in the cytoplasm of the insect cells, sometimes associated with tubular structures, which is one of the characteristic features in tissues infected with reoviruses. The virus was p...
