The Philippine Bureau of Agricultural Research reports the following most common cacao pests and diseases in the Philippines: \textit{black pod rot, vascular streak dieback, cacao pod borer, helopeltis, and cacao stem borer}. Black Pod Rotting alone causes 20 to 30\% pod losses, and kills up to 10\% of trees annually through stem cankers \cite{guest2007black}.  %%As shown in Figure \ref{fig:infectedPods}, one will observe a clear boundary between the healthy and infected part of the pod. The infected part of the pod is discolored and it spreads quickly to the whole pod surface, turning the pod into blackish brown. Sudjud et al. \cite{sudjud2013intensity} observed that the discoloration usually started from the tip of the pod or near the stem. The disease can occur in any age group of the pod. However, if the infected pod is still young, it cannot be harvested unlike pods that have already ripened. %%  To reduce the damage of pests ad diseases in the cacao industry, visual surveillance of cacao pods are done. As of today, farmers and agricultural technicians manually performs the visual inspection of the pods while comparing them an aid to assess the severity of the disease. This aids comes in form of a severity index for cacao pod rot based on a scale from 0 to 5 (see Figure \ref{fig:visualAid} below), patterned from Alvindia and Acda’s work on managing anthracnose of mangoes \cite{alvindia2015revisiting}.   %%They assign an index of 0 if there is no visible spot in the mango; 1 if there is one depressed spot that is dark in color and is 1 to 5 mm in diameter on the epidermis of the fruit; 2 if the fruit has 2 to 3 depressed spots that is dark in color and is 1 to 5 mm in diameter; 3 if 2-3 depressed spots, dark in color with more than 5 mm in diameter; 4 if more than 3 depressed spots, dark in color with more than 5 mm in diameter; and 5 if the depressed spots merged.
