A Review of Successes and Impeding Challenges of IoT-Based Insect Pest Detection Systems for Estimating Agroecosystem Health and Productivity of Cotton

Abstract

Using artificial intelligence (AI) and the IoT (Internet of Things) is a primary focus of applied engineering research to improve agricultural efficiency. This review paper summarizes the engagement of artificial intelligence models and IoT techniques in detecting, classifying, and counting cotton insect pests and corresponding beneficial insects. The effectiveness and limitations of AI and IoT techniques in various cotton agricultural settings were comprehensively reviewed. This review indicates that insects can be detected with an accuracy of between 70 and 98% using camera/microphone sensors and enhanced deep learning algorithms. However, despite the numerous pests and beneficial insects, only a few species were targeted for detection and classification by AI and IoT systems. Not surprisingly, due to the challenges of identifying immature and predatory insects, few studies have designed systems to detect and characterize them. The location of the insects, sufficient data size, concentrated insects on the image, and similarity in species appearance are major obstacles when implementing AI. Similarly, IoT is constrained by a lack of effective field distance between sensors when targeting insects according to their estimated population size. Based on this study, the number of pest species monitored by AI and IoT technologies should be increased while improving the system’s detection accuracy.

A Comprehensive Review on Intelligent Techniques in Crop Pests and Diseases

“…To improve pest management, ANN and remote sensing data for cotton [32] detected Cotton Bollworms with 87% accuracy. Last, tomatoes [33] showed 98.3% accuracy in the YOLOv3 model in Early Blight diagnosis, avoiding disease spread and lowering losses. These developments demonstrate how AI transforms agriculture, fosters effective crop production, and reduces dependency on hazardous pesticides.AI offers hope for a resilient and fruitful future in international agriculture [37].…”

Navigating the Sea of Data: A Comprehensive Review on Data Analysis in Maritime IoT Applications

By applying data analysis to the information collected from IoT devices, maritime stakeholders can gain meaningful insights to enhance operational efficiency, improve safety, and make strategic decisions [75].…”

“…By analyzing data from various sensors and IoT devices on a vessel, potential safety hazards can be identified and addressed promptly. This contributes to the enhancement of safety measures, reducing the risk of maritime accidents and ensuring the well-being of the crew and the integrity of the cargo [75].…”

Improved Artificial Ecosystem Optimizer with Deep-Learning-Based Insect Detection and Classification for Agricultural Sector

“…Such sensors gather vital data, namely soil moisture, temperature, humidity, and the images of crops along with the surrounding vegetation. With real-time data analytics and processing techniques, the system rapidly identifies the pest outbreaks and immediately alerts the agricultural experts or farmers, thus allowing them to proceed with timely and targeted pest management measures [2]. This combination of the IoT and pest classification techniques has the potential to revolutionize pest control in agriculture, causing more sustained practices, decreased pesticide use, and, ultimately, maximum crop yields.…”
