Effect of biopesticides against stem borer (Lophobaris piperis) and Thrips sp. on pepper (Piper nigrum)

Abstract

One of the pepper crop production obstacles is the presence of pests. Several pests that often attack pepper plants in the Sukamulya Experimental Station is pepper stem borer (Lophobaris piperis) and Thrips sp. We studied the effect of biopesticides of botanical pesticides and biological pesticides at the Sukamulya Experimental Station, Sukabumi – West Java in 2020 against the pepper stem borer L. piperis and Thrips sp. in pepper plantation. The research was designed in a randomized block with three treatments, namely (1) botanical pesticides, (2) biological pesticides and (3) control (water), and nine replications. The treatment application is carried out once a month, done immediately after observing the intensity of the pest attack. The results showed that the attack of pepper stem borer was low (below 10%), so the effect of the treatment could not be seen significantly. The Thrips attack was high enough, it was seen that there was the ability of botanical pesticides to reduce the intensity of the attack. Meanwhile, the biological pesticide had not yet shown its ability to reduce the intensity of Thrips sp.
