Monitoring Notes for Spotting Bugs in
Monitor the crop every two weeks (more often if you wish) during periods when the crop is susceptible to bug damage.
Randomly select then mark 10 trees, more if you wish (of same variety if possible) in a hot spot area and 10 trees in the rest of the block. If you don't have a distinct hot spot, select one section that might have more pressure than the rest. Otherwise, just do one"plot" but increase your sample to 20 trees (40 for passionfruit and pawpaw). Give us a call if you have any queries about this.
For passionfruit and pawpaw inspect 20 or more trees or plants is each plot.
Return to these trees each time you monitor.
By marking trees we are trying to avoid a bias.
Select 10 fruit (or shoots in passionfruit) at random on each tree - you shouldn't have to pick the fruit.
As you inspect fruit look out for bugs and record accordingly. If you want to note if a nymph is small etc do this in "comments". Remember that, if you are finding nymphs in the crop then the bugs are breeding in the crop.
Inspect each fruit for FSB damage.
Record number of fruit (or shoots) that have old or new damage.
In avocados, internal damage is indicated by depressions and damage on the skin but only until full fruit size
(maybe 2 months before harvest). Damage caused from then to harvest is mostly not visible until fruit is skinned."
