- Abstract
The seasonality of infestation pest and population dynamics of Dicladispa armigera (Chrysomelidae: Coleoptera) commonly known as Rice Hispa were studied at Paroka experimental farm, University of Agriculture, Faisalabad, Pakistan in two consecutive years 2010-2011 on February and September season crops of sugarcane, respectively. A trial was also carried out during 2012 to find out the most effective insecticide against the pest. The results showed that peak population level of the pest (6-7 adults/sweep) was found in June during both years (2010 and 2011). The pest was absent in sweeps from November to January. Pest population in February and September crop was 2.611±0.543 and 1.944±0.383 per sweep, respectively. Damaged leaf area was higher in the months of June-September ranging from 30-70 percent in February crop and 10-35 percent in September crop. Temperature was the most important factor that favored the population with r =0.4375 to 0.7784. Damaged leaf area was highly significantly correlated with adult population in both season crops with r =0.8804 and r =0.7731, respectively. Percentage reduction of adult population was found maximum (94%) in the chlorpyrifos treatment showing rapid knockdown effects followed by acetamiprid (70%) and fenpropathrin (58.5%). Minimum of damaged leaf area and higher yields were also recorded in chlorpyrifos (6.2% and 81 kg/plot) and acetamiprid (7.26% and 74 kg/plot) treatments.
