Abstract

The cashew tree (Anacardium occidentale) is a tropical plant that yields the world's most consumed nut. Anacampsis phytomiella (Lepidoptera: Gelechiidae) is the primary pest that infests cashew nuts, leading to losses of up to 80%. The comprehension of the spatiotemporal dynamics of pests enables enhanced planning of sampling and control methods. Artificial neural networks (ANNs) are computational models in machine learning with high predictive capability. Thus, the objective of this study was to determine a seasonal dynamic model of A. phytomiella using ANNs. Over 3 years, the pest attack intensity and climatic elements were monitored in two cashew orchards. A total of 1716 ANN models were determined. The model predictors included the time of plant fruiting, average air temperature, dew point, atmospheric pressure and rainfall. The temperature, atmospheric pressure and time of plant fruiting had a positive effect on pest infestation, while the opposite occurred with rainfall. The pest infestation curve in relation to the dew point exhibited a point of maximum. The model successfully predicted the intensity of A. phytomiella infestation across different years, plant fruiting stages and pest densities. Therefore, the ANN model determined in this study is promising for predicting the intensity of A. phytomiella infestation in cashew orchards.

基于人工神经网络的腰果严重害虫时间动态预测模型
腰果树(Anacardium occidentale)是一种热带植物,出产世界上消费最多的坚果。腰果小蠹蛾(鳞翅目:蠓科)是腰果的主要害虫,可造成高达80%的损失。对害虫时空动态的理解可以增强采样和控制方法的规划。人工神经网络(ann)是机器学习中具有高度预测能力的计算模型。因此,本研究的目的是利用人工神经网络建立一种植物芽孢杆菌的季节性动态模型。在3年多的时间里,对两个腰果果园的害虫发生强度和气候要素进行了监测。共确定了1716个人工神经网络模型。模型预测因子包括植物结实时间、平均气温、露点、大气压力和降雨量。温度、气压和植物结实时间对害虫的发生有积极影响,而降雨量对害虫的发生有相反影响。与露点有关的害虫侵害曲线呈现出一个最大值点。该模型成功地预测了不同年份、不同果期和不同虫害密度的棉铃虫侵染强度。因此,本研究建立的人工神经网络模型有望用于预测腰果果霉侵染强度。
