The tropical climate shift is causing herbivores to emerge almost ceaselessly throughout the year in certain regions exhibiting homodynamic cycles and unbalanced biodiversity. Crop management and pest management are being viewed as separate activities, with recent focus on sustainability. Even though there is a great deal of information on crop loss assessment, systems analysis, systems modelling, individual pest sciences, and pest management, the Integrated Pest Management (IPM) concept is not frequently deployed. The IPM system is a multi-tactic approach to pest management in agricultural production that takes into account economic, environmental, ecological, and human health implications. This paper provides an overview of key achievements in the development of management strategies, including the transition from a specific level of pest control that focuses on the suppression of target pests to an eco-friendlier and/or systems approach to pest management that employs a variety of non-chemical options as well as the judicious use of pesticides. The agroecological protection techniques and their integration to sustainably minimise pest risks are also reviewed here and describe technological advances in tropical pest management using host resistance, semiochemicals, natural enemies, selective pesticides, ecological engineering and habitat management which promotes sustainable pest management.

“…The activity of mango leaf Webber in the mango orchards start in July and it wreaks havoc up to December (ICAR, 2014). The pest in recent years has taken serious forms in orchards of Nepal as well (Venkata Rami Reddy et al, 2018). Orchards located in Sarlahi, Saptari, Siraha, Mahottari and other districts of eastern Nepal which are a top producer of mango in Nepal are also found to suffer significantly from Mango leaf Webber.…”

Mango Leaf Webber (Orthaga euadrusalis Walker, (Pyralidae: Lepidoptera); A Potential Threat in Tropical Plains of Nepal

et al. 2022

Mango Leaf Webber (Orthaga euadrusalis Walker, 1858) is a phytophagous insect feeding on mango leaves by scraping the leaf surface leaving behind midribs and habitat inside the webbed leaf bunch, which is one of the major pests of mango in south Asian nations including Nepal. The infestation of the pest has the potential to cause production loss of 25-100% if not managed. Thus, the management of the pest is crucial to protect mango production and collateral economics. For management, the web nest can be scraped off and burnt along with pupa and larva. Integrated management practices include biological methods using predators like Brachymeria lasus, Hormius, Hormiusa, Pediobius bruchicida, Oecama sp., etc. pathogens like Serratia marcescens and Beauveria bassiana, etc., pruning and removal of old and infested branches and planting resistant variety like Amrapali, the legal method by regulating mobility of plant parts as well as the chemical method by using chemical pesticides like Quinalphos, Cypermethrin, Chlorpyriphos, Acephate and botanical pesticides like Nimbicidine, Nemactine, etc. for management of the pest. The management methods given in this paper would be a valuable resource for mango growers, researchers, and consumers in managing the mango leaf Webber problem.

“…Mango planting areas are widely distributed in tropical and subtropical regions, with Asia's mango production accounting for 72.9% of the world's production [1]. However, due to the climate's high temperature and humidity, pests and disease outbreaks in mango orchards are frequent, becoming a difficult and painful aspect of mango plant protection operations [2]. Thrips is the most important insect pest in Asian mango, which mainly inserts its mouthparts into the mango leaf or fruit flesh to suck the sap, destroying the internal tissues and chlorophyll cells, thus affecting the gathering of water and nutrients required for photosynthesis [3].…”

Thrips constitute the primary pest responsible for reducing mango yield and quality every year in Asia. Therefore, the efficient monitoring of thrips damage across mango orchards on a large scale to aid farmers in devising rational pesticide application strategies poses a significant challenge within the current mango industry. This study designs a mango thrips damage inversion prediction method based on the maximum likelihood classifier (MLC). Initially, drone multispectral remote sensing technology is utilized to acquire multispectral data from mango orchards, which are then combined with ground hyperspectral information to identify sensitive bands indicative of mango leaf damage caused by thrips. Subsequently, correlation analysis is conducted on various vegetation indices, leading to the selection of the Greenness Normalized Difference Vegetation Index (GNDVI), which exhibits a strong correlation coefficient of 0.82, as the spectral characteristic parameter for the inversion prediction model. The construction of a remote sensing prediction model for thrips damage distribution in mango orchards is then undertaken based on the MLC. Acknowledging the bias-variance trade-off inherent in the MLC when processing spectral data and its potential limitations in feature extraction and robustness, this study proposes a modification wherein neighboring pixels are weighted differently to enhance the model’s feature extraction capabilities. Experimental results show that the novel MLC maintains stable estimation levels across various numbers of domain pixels, achieving an inversion accuracy of 91.23%. Through the reconstruction of the pixel matrix, the damage distribution of thrips in mango orchards can be swiftly and comprehensively visualized over extensive areas.
