Abstract

Many lepidopterans are among the diverse arthropod pests that attack tomato crop. Some of these lepidopterans are more problematic and widespread than others. This chapter concerns nine of the particularly problematic lepidopterans on tomatoes. Because of their assorted bionomics, some species are more damaging in certain regions. These lepidopterans attack tomato foliage, stems, immature and ripe fruits, and they all have hosts other than tomato. As with other tomato pests, several approaches are available to manage these pests, including plant resistance, biological control, sanitation, trapping, mating disruption, use of scouting and thresholds before making insecticide treatments, and selection of narrow spectrum insecticides that minimally impact natural enemies. Growers are advised to use an integrative approach that utilizes as many of these strategies as possible.

Integrated effect of insecticide and sex pheromone on the tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae)
2023, Crop Protection
The tomato leafminer, Tuta absoluta (Meyrick), is currently a major threat to tomato globally. Growers in Ethiopia rely on insecticides to control the pest, which is not sustainable because of the insect's ability to develop resistance fast. The rational use of pesticides is useful to delay pesticide resistance. The integrated effect of sex pheromone and insecticide in the population of the tomato leafminer and its damage on tomato was investigated for two seasons between 2020 and 2021 at Melkassa center of the Ethiopian Institute of Agricultural Research (EIAR). Treatments consisted of trapping using sex pheromone alone, insecticide use alone and a combination of trapping using sex pheromone and insecticide (integrated treatment) along with the untreated control. Four fields, each with three replicates of plots for each treatment were used by keeping each field wide apart to minimize the movement of adult population of the insect. Treatment effects were assessed by counting the immature stages of the insect and damage both on the leaves and tomato fruits. Treatments differed significantly for mining larvae but not for the number of eggs. Leaf damage was significantly higher in the untreated control than in the rest of the treatments. In both years, similar trends of results for the percentage of damaged fruits were observed, which was lowest in the integrated treatment followed by insecticide alone, pheromone trap alone and untreated control. Results from this study suggest the need to integrate pheromone traps with insecticides to achieve better protection from Tuta absoluta damage on tomato.
A review on biology and possible management strategies of tomato leaf miner, Tuta absoluta (Meyrick), Lepidoptera: Gelechiidae in Nepal
2023, Heliyon
Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), Tomato Leaf Miner (TLM) moth, is one of the notorious oligophagous pests of solanaceous crops that mines primarily on mesophyll of leaves as well bore tomato fruits. In Nepal, T. absoluta, the pest that has a potential to create loss up to 100%, was detected in 2016 in a commercial tomato farm at Kathmandu. So, the farmers and researchers must heed for effective management contrivance to improve the yield of tomato in Nepal. The devastating nature of T. absoluta causes its unusual proliferation so that it needs dire study of its host range, potential damage and sustainable management strategies. We discussed the data and information on T. absoluta available in several research papers comprehensively and provided succinct information on occurrence of T. absoluta in the world, its biology, life cycle, host plants, yield loss due to T. absoluta and several novel control tactics which helps farmers, researchers, policy makers to sustainably rise the tomato production in Nepal as well as in global context to attain food security. Sustainable pest management strategies such as Integrated Pests Management (IPM) approaches incorporating and prioritizing biological control methods with usage of chemical pesticides with less toxic active ingredient can be encouraged to the farmers for controlling the pests sustainably.
Synthesis of clay-reduced graphene oxide composite catalysts for the electrochemical detection of flubendiamide: application in food samples

Some of these pests are more troublesome and widespread than others. Lepidopteran pests feed in a variety of ways, such as on foliage, stems, immature fruit and ripe fruit [2]. The problems caused by these lepidopterans on vegetable crops can be solved using a variety of integrated pest management (IPM) technologies [3].
This paper presents a simple and low-cost approach to synthesizing reduced graphene oxide/clay modified pencil electrode (rGO/Clay/PGE) through thermal reduction of GO/Clay for ultrasensitive detection of Flubendiamide (FBD). The graphene oxide (GO) was prepared by exfoliation of graphite with an eco-friendly procedure. The as-produced rGO/Clay was characterized by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), and Scanning electron microscopy (SEM). The electrochemical behavior of the synthesized electrode was studied by cyclic voltammetry (CV). Under optimized conditions, rGO/Clay/PGE exhibited excellent analytical properties toward FBD determination. A calibration curve was well-established from 0.1 to 100 μmol/L for FBD with a detection limit of 0.006 μmol/L. The method was successfully adopted for the detection of FBD in white rice samples.
