We noticed some of the guava fruits at our farm are having small borers which burrow into the fruit and make it mushy inside. Please see attached pics and please give your suggestions as to how we can control this. We have installed light traps and fruit fly pheromone traps
First choice would be non- chemical methods but not averse to off the shelf insecticides.
The first pic shows small holes thru which the borers go in and out
The second pic is a cut away of the inside
The third pic is of the small borer, it is the brown one at almost the centre of the pic
