Summary, etc. | The population dynamics and management of coconut root grub (Leucopholis coneophora Burmister) was studied in the laboratory and field of College of Agriculture, Padnekkad, Kasaragod, Kerala during 2013-14. In the study on efficiency of light traps in collecting the adult beetles, the mercury light trap has recorded the prolonged collection, highest number of beetles and female beetles followed by ultraviolet trap and black light trap. The daily maximum and minimum temperature and soil temperature negatively and rainfall positively correlated with adult emergence. Larval population has shown a decreasing trend from August to February and highest larval population per coconut basin was 29.96. Laboratory plastic cup experiments, field pot experiments and field cage experiments were conducted to develop management measures. In the plastic cup studies, 100 per cent mortality was observed in the treatments with Novaluron, Clothianidin, Azadirachtin 1500 ppm @ 5ml/L, 10ml/L, 15ml/L and Malathion which are on par with CNSL 2% (80) and Chlorpyrifos (66). In the pot studies, maximum mortality of 98 per cent was observed in treatments with Azadirachtin 10ml/L and 15ml/L followed by Malathion with 97 per cent and Clothianidin with 87 per cent which are significantly better. In the cage studies, the treatment viz. Azadirachtin 15ml/L gave highest mortality (97 per cent) followed by Malathion (87), Clothianidin (73), Azadirachtin10ml/L (70) and Azadirachtin 5ml/L (63). There was no mortality in absolute control. The EPN Heterorhabditis indica inflicted no mortality. In no-choice test conducted to study the repellency of botanicals to root grub larva, significantly highest repellency was observed in cashew nut shell liquid (CNSL) 2 % followed by Azadirachtin concentrations. In starvation test, significantly highest repellency was observed in Azadirachtin 1500 ppm 15 ml/L. followed by CNSL 2%. In phytotoxicty studies, CNSL 2, 4 and 6% significantly inhibited the germination and growth parameters of cow pea. |
