Abstract

ABSTRACT This study aimed to present the design and field test results of an LED (light emitting diode) lamp for integrated pest management (IPM) and other entomological studies. The light spectrum of the LEDs was tuned to optimize insect attraction and lower energy consumption. An electronic circuit with control software was integrated with the lamp, enabling it to operate in standalone mode, automatically identify night and day, monitor and control the battery charge with energy from a photovoltaic solar panel, protect the battery against over-discharge, and provide feedback about the operating status of the system. Additionally, energy consumption is about five times lower than that of the fluorescent lamp, reducing the battery and solar panel size needed for its energy supply. In the 2017/2018 growing season, the smart LED lamp was installed in a Sonne light trap in an irrigated rice field, and the total number of insects captured was compared with the number collected in a conventional light trap fitted with a traditional 15 W black light fluorescent lamp. Total captures in the Sonne trap were approximately three times greater than in the conventional system.

Highlights

Light traps are used to attract and catch nocturnal insects via positive phototropism (Shimoda & Honda, 2013; Sheikh et al, 2016)

Summary

Introduction

Light traps are used to attract and catch nocturnal insects via positive phototropism (Shimoda & Honda, 2013; Sheikh et al, 2016). This solution is used to monitor pests and their natural enemies in several applications, including integrated pest management (Aguiar et al, 2010; Hickel et al, 2015; Baehaki et al, 2017; Silva, 2017; Zhang et al, 2020), and research on species diversity and habitat characterization (Price & Baker, 2016; Infusino et al, 2017). Optimal operation of the “Luiz de Queiroz” trap requires a battery with 70 Ah storage capacity and a 60 W solar panel (Zanuncio et al, 1991; Silva, 2017)
