Inspection of insect sticky paper traps is an essential task for an effective integrated pest management (IPM) programme. However, identification and counting of the insect pests stuck on the traps is a very cumbersome task. Therefore, an efficient approach is needed to alleviate the problem and to provide timely information on insect pests. In thi...

The unavailability and variability of training samples are the two essential concerns in the training of deep neural network models for image classification. For automated image monitoring systems, these problems are difficult when training a model through supervised learning methods because of the time and effort required. This paper proposes an a...

Background: Main bottleneck in facilitating integrated pest management (IPM) is the unavailability of reliable and immediate crop damage data. Without sufficient insect pest and plant disease information, farm managers are unable to make proper decisions to prevent crop damage. This work aims to present how an integrated system was able to drive f...

One of the issues in training a deep learning-based object detector is the imbalance in the number of objects found in an image. This makes an object detector inadequately trained on different backgrounds and varying numbers of objects. To propose a solution to this problem, this work presents a method for generating synthetic cocoa pod borer (CPB)...

Indoor crop production requires multiple trials to determine which conditions and parameters help in optimizing plant growth. A solution for this problem is to promptly detect nutrient deficiency. This paper proposes an artificial intelligence of things (AIoT)-based system that aims to monitor plant growth and detect stunted plant growth caused by...

The cocoa pod borer (CPB) (Conopomorpha cramerella) is a very small insect pest native to Asia and Oceania. CPBs cause extensive damage by boring holes into cocoa pod husks and cause premature ripening. Due to its resemblance to other insect pest species, most farm managers fail to recognize it; this makes farm managers unable to avert crop damage....

Heat stress is one of the major challenges in livestock production and management. Due to heat stress, dairy cows experience health and fertility problems as well as lower milk production, resulting in great economic losses to dairy farmers. One of the approaches to assessing heat stress in dairy cows is by monitoring their respiration rate (RR). M...

Pollen foraging efficiency provides vital information for the behavioral research on honey bees. The pollen production of beehives can be measured by manually weighing the pollen collected from pollen traps. For long-term pollen foraging monitoring, this approach is both inefficient and laborious. This study presents an efficient method for automat...

The population loss rate of a honey bee colony is a critical index to verify its health condition. Forecasting models for the population loss rate of a honey bee colony can be an essential tool in honey bee health management and pave away to early warning methods in the understanding of potential abnormalities affecting a honey bee colony. This wor...

The inability to classify insects up to the species level is the current limitation of recently developed automated insect recognition algorithms. Yet, there are situations in integrated pest management (IPM) that call for more precise classification of insects. This research proposes an effective method for automated identification of low-resoluti...

With the advances of computer vision over the recent years, its applications have extended from handling static images to tackling the challenging domain of video analysis, with human activity recognition being among the core research topics. However, recognizing and recording the activity of agricultural workers through surveillance videos is stil...

Tomato (Solanum lycopersicum L.) is a high-value crop all over the world. This means that systematic and intensive management of tomato crops is necessary.

The application of deep neural networks in computer vision has remarkably improved the reliability of automated insect pest identification algorithms. However, to build a robust deep neural network classifier model, sufficient number of image data is necessary. In preparing image data, collection and annotation of large datasets can be labor-intens...

Greenhouse whitefly (Trialeurodes vaporariorum) is a major insect pest of greenhouse crops. To prevent the damage caused by whiteflies, farmers control the population of whiteflies by spraying pesticides in a regular basis. However, pesticides are costly and may affect the environment and health of farmers. To provide a more efficient way for apply...
