Efficacy of Different Coloured Sticky Traps Against Thrips of Chilli

Abstract

The field experiment was conducted at Spices Research Centre, Shibganj, Bogura, Bangladesh during Rabi season of 2017-18 to study the color preference of Scirtothrips dorsalis in chilli. The treatments were T1= Blue trap @40 trap/ha; T2= Yellow trap @40 trap/ha; T3= White trap @40 trap/ha; T4= Green trap @40 trap/ha and T5= Pink trap @40 trap/ha. Among the color traps used, at 35 days after installation (DAI) of trap blue color attracted highest (8.44 thrips/ sq. inch area of trap) number of S. dorsalis adults followed by white (5.43 thrips/ sq. inch area of trap), yellow (4.30 thrips/ sq. inch area of trap), green (3.52 thrips/ sq. inch area of trap) and pink (3.40 thrips/ sq. inch area of trap) color. Blue coloured sticky trap also attracted comparatively a smaller number of beneficial insects and can be used for relative estimate of S. dorsalis population and also for monitoring and mass trapping as a component of IPM program.

Comparison of Coloured Sticky Traps against Bean Flower Thrips (Karny) (Thysanoptera: Megalurothrips distalis Thripidae) in Summer Mung Bean

“…Similarly, M. sjostedti Trybom on French bean has been reported to be more attracted towards blue trap (Muvea et al 2014). Blue coloured sticky traps were most effective for in open field S. dorsalis rose crop (Sridhar and Naik 2015) and on chilli crop as compared to white, yellow, green and pink coloured traps (Hossain et al 2020). Similarly blue traps were useful than yellow for in fruit trees and green house rose F. occidentalis (Broughton andHarrison 2012, Khavand et al 2019) and for F. bispinosa in olive grove (Allan and Gillett-Kaufman 2018).…”

Determining the technical and economic feasibility of combining pest control techniques in open field and netting house chili cultivation systems

“…There was no insecticide applied to control thrips and armyworms in both open field and netting house since plant damages were below its control threshold (Figure 1). Yellow sticky traps have been found to reduce thrips dispersal, while plastic mulch can prevent pests from pupating in the soil (Haerul et al 2020;Hossain et al 2020). There was no insecticide applied to control armyworms since the related crop damage was below its control threshold (less than 12.5%) in the open field, and no armyworms were found inside the netting house (Figure 2).…”

“…The study aimed to determine the technical and economic feasibility of the combinations of various pest control techniques in open field and netting house chilli cultivation systems. The control techniques applied in this study included the application of sweet corn barrier (Ramazeame et al 2015), thiamethoxam (Mason et al 2000), silver plastic mulch (Razzak & Seal 2017), light traps (Singh et al 2014), fruit fly traps (Mulyadi et al 2021), yellow sticky traps (Hossain et al 2020), control threshold and fungicides application strategy (Moekasan & Prabaningrum 2017).…”

Drip irrigation system: useful technique to improve chili production

“…Thus, there was no insecticide application was applied in the field. The implementation of plastic mulch and yellow sticky traps on both systems have known to be effective in reducing thrips populations by preventing thrips from pupaing in the soil and trapping pest in sticky traps [24][25][26]. The crop damage due to the armyworm S. litura attack is presented in Figure 3.…”
