Using a smart watering system for controlling thrips inside mangosteen canopy in Nakhon Si Thammarat province, Southern Thailand

Abstract

Mangosteen (Garcinia mangostana) production is important in Thailand for domestic consumption and export in other countries. High-quality mangosteen is considered when there is no scar on the surface. Thrips infestation is a common cause of scars which reduces the market value of mangosteen. Thrips density is highly affected by humidity; higher humidity decreases thrips numbers. In this study, a smart watering system was designed, developed, and used to increase the humidity and reduce thrips numbers inside mangosteen canopy in Southern Thailand. The system successfully reduced the thrips numbers. This study also shows a negative correlation between humidity and thrips numbers.

Potential development of mangosteen (Garcinia mangostana L.) through optimizing land use in Pati, Central Java, Indonesia

“…Even though the plant has dense canopy, but it does not affect the moisture which influence the fruit quality. Moisture is a significant risk that affects the growth of thrips population [31]. The trunk has cylindrical shape with a curved upright branching.…”

Integration of IoT-Enabled Technologies and Artificial Intelligence (AI) for Smart City Scenario: Recent Advancements and Future Trends

“…Various smart city applications include sensors, actuators, and smart device technologies in this context. There is a vast array of commercial devices available that can measure different physical quantities and external variables, i.e., sensors for measuring humidity [71,72], temperature [73], environment monitoring [74], water nutrient monitoring [75], etc. Actuators are used for controlling/moving other objects or systems through physical interaction or virtual control [76].…”
