Abstract

This research aimed to find out an abundance of Thrips sp. population on Integrated Pest Management (IPM) and conventional farming at chilli plantation. The research was conducted on August until November 2012 at the Bayem Village, Sub-distric Kasembon, Malang, East Java and Entomology Laboratory, Departement of Plant Protection, Agriculture Faculty, Brawijaya University. The methods to determine abundance population Thrips sp. was using quadrant with 4 plants samples in 1 beds were taken. The observation was using 16 plants, on the each treatment of IPM and conventional farming. The result showed that the population of Thrips sp. (nymph) on IPM and conventional was not significantly different, while the population of Thrips sp. (adult) in the IPM treatment was significantly higher compared to conventional. Plant height on IPM treatment was higher than conventional treatment. The statistical analysis on Thrips sp. attacks indicated, that the intensity of damage on IPM treatment (0.16 %) and conventional treatment (0,14 %) were not significantly different. The yield of chilli on the IPM (31%) was significantly higher than compared to conventional treatment. Chilli cultivation costs on IPM was higher (2.5%) rather than the conventional. The yield of chilli plant per hectare on IPM had advantage higher (37%) than conventional. The calculation of the BCR at the IPM was higher (27%) than the conventional farming. Key words: Abundance, analysis of farming , IPM, Thrips sp.

Highlights

Chilli (Capsicum annuum L.) is a vegetable commodity that has a high economic value
Total population nymph of Thrips sp was not significantly different between Integrated Pest Management (IPM) and conventional, while the number of imago population in IPM was higher than conventional treatment
Plant height in IPM was higher than conventional treatment

Summary

Introduction

Chilli (Capsicum annuum L.) is a vegetable commodity that has a high economic value. Chilli needs continue to increase every year in line with the increasing number of population and the development of industries that require raw materials of chilli [1]. The productivity of chilli can be reduced due to pest disturbance. Main pest on the chilli is Thrips sp. In control of Thrips sp., Farmers are using various of pesticides and it have a negative impact such as reducing the abundance of natural enemies in chilli. To mitigate the negative impacts, an agroecosystem management by using Integrated Pest Management (IPM) on the field is required. IPM is an ecosystem-based strategy that focuses on long-term prevention of pests or their damage through a combination of techniques such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties. The application of polyculture in the IPM will be able to present the fauna diversity that will increase diversity of natural enemies. ‘Western Flower Thrips (Thysanoptera : Thripidae) in Greenhouse : Population Dynamics, Distribution on Plant and Assositation with Predators’, J.
