Abstract Whitebacked planthopper, Sogatella furcifera Horvath (Homoptera: Delphacidae) is a migratory and very serious pest of rice crop in Pakistan. The experiment was carried out to study the population dynamics by capturing Whitebacked planthopper (WBPH) in light traps and its association with abiotic factors (temperature, relative humidity and rainfall). Population dynamics was monitored using light traps installed in four rice growing districts viz., Sheikhupura, Gujranwala, Narowal and Bahawalnagar of Punjab province in Pakistan. Results revealed that mostly population of WBPH started to appear on traps during first week of September and peak population of WBPH recorded in 2nd and 3rd week of October with a decline started in the end of November. Weather variables shown significant relationship with WBPH population dynamics. Rainfall showed positive increased influence synchronization with pest population in light traps. The correlation data exhibited positive correlation of WBPH population on light trap with relative humidity in September. Minimum temperature disclosed significant and negative association with WBPH population in October. Results of the present investigation suggest that weather variables significantly affected the population dynamics of S. furcifera. Keywords Sogatella furcifera . Population dynamics .

Whitebacked planthopper (WBPH) is widely distributed and serious insect pest of rice crop in Pakistan (Mochida et al. 1982). WBPH not only damage directly to the crop by ovipositing and feeding on the plants but it also transmits the southern rice black streaked dwarf virus (SRBSDV) (Zhou et al. 2008; Guo et al. 2013) and rice black streak dwarf virus −2 (RBSDV-2) (Zhang et al. 2008). Due to heavy attack crop looks scorched (which is called hopper burn) causing reduced photosynthesis and crop growth (Sumikarsih et al. 2019). For example in China rice planthoppers are the most destructive agricultural insect pests which can damage an area of about 20 million ha annual
