Cumulative percentage reduction of third-instar larvae of Leucopholis lepidophora in areca nut field with different treatments 3 and 6 weeks after application in North Canara district, Karnataka, India during 2015–2017. Different letters on the top of error bars indicate statistically different values for different nematode concentrations using Tukey’s test (P < 0.05). Bars = standard error. Sa, Steinernema abbasi; Hi, Heterorhabditis indica; 1 = 1.7 × 105 IJs palm−1, 2 = 3.5× 105 IJs palm−1. Chlorpyrifos was used at the rate of 6 ml palm−1 as a drench application
