CBB IPM - 30 Tree Sampling Method for CBB Monitoring - Part I - In the Field - Duration: 3:22.

[birds chirping]

(Narrator) The 30 Tree Sampling Method for coffee berry borer monitoring helps

determine the beetle population on your farm.

It gives an estimate on your berry infestation,

and bean damage, as well as help you to determine the most effective

times to spray Beauveria bassiana.

This video will go over step 1 of the sampling.

Step two and three can be found in the second video.

To begin step 1,

you'll start monitoring and sampling around 30 days after your initial

flowering. However you may want to start sooner if your trap catch or your own

observations indicate an increase in CBB activity.

To start sampling you'll need

the following items: a clipboard with a map of your farm, a 30 tree sampling

worksheet, a knife, pen or pencil, permanent marker, storage bag, flagging

tape, calculator, tally counter, and any visual aids that you might need such as

a hand lens or reading glasses.

Once you're in the field, mark a zig-zag

pattern on your map to use as a guide while you sample.

Choose at least 12 trees per acre

or 30 trees per hectare to sample along the zigzag.

Here you can see our map is simply drawn with notes on the physical features and the number

of rows of coffee. If needed you can add other features such as the pruning stage,

coffee variety, microclimate, or even management practices.

Please tailor your farm map based on your needs.

Begin sampling at tree number 1,

a tree close to the corner of the coffee field. Randomly select the coffee branch

found on the middle of the tree that has around 30 to 120 berries.

Count the total number of green berries on the branch and remember not to count any ripe

cherry. If there aren't enough green berries on the branch, you can count off

the two branches. Record the total number of green berries on column A of your worksheet.

Next, count the number of green berries infested with CBB, which are

unripened berries with holes at the flower end of the fruit.

Here are some examples of green berries that are infested with CBB. Record the total

number of infested green berries on column B of your worksheet.

Afterwards, randomly pick 3 to 4 CBB infested green berries from the branch and place

it your storage bag. If you're unable to find infested green berries on your

branch, you can collect them from a neighboring branch.

If you notice anything interesting about the trees in your area, record notes on column C of

your worksheet. For example you can take notes on hotspots, raisins, unhealthy or

diseased trees, or any other issues with insects or pests. If you need to come

back to a tree on a later date, you can flag the tree and then continue your sampling.

Next check your map and move towards the next sample tree, but before

you reach the tree..STOP and choose your sample branch from a distance. This

will help you avoid biasing your data, if you tend to be looking for branches with

high infestation. Once chosen repeat the previous steps and continue until

all the trees have been sampled.

If you sampled from 30 trees, you should have

about a 100 infested green berries. Immediately proceed to step two and

three, which is covered in the next video.

CBB IPM - 30 Tree Sampling Method for CBB Monitoring - Part II - Dissection and Decision - Duration: 3:13.

[Bird chirping]

(Narrator) This video will cover the second part of the 30 Tree Sampling Method

for coffee berry borer monitoring.

It will go over how to determine the CBB positions in

the berries and when it's a good time to spray Beauveria bassiana.

After collecting your berries from the field, you'll need to process them

immediately to determine the beetles position inside the berries.

The AB position is when CBB has just started to bore into the fruit and is still visible.

In this position, CBB can be controlled with Beauveria bassiana or other pesticides.

While in the CD position, the beetle has bored further in, causing

damage to the bean, and at which point cannot effectively be treated with insecticides.

To determine what position the CBB is in,

you'll need to dissect your green berries.

Carefully cut each berry and determine if the beetle is...

AB Alive,

AB Dead,

AB Absent,

or CD whether the beetle is alive, dead, or absent.

Use the worksheet to tally your findings.

Please make sure not to kill the beetle while opening the berry.

Here are different ways to carefully dissect

your berries using a knife or pruning shears.

If it's difficult to see the beetle,

use visual aids and have ample light during dissection.

Once you have dissected all the berries,

complete the calculations on the worksheet.

For % infestation,

you'll need to use the numbers collected in the field.

Add all the numbers in column A,

to get the total number of green berries.

Then add all the numbers in column B,

to get the total number of infested berries.

Next,

divide the column B total, by the column A total, and multiply it by a hundred.

For % AB Alive,

divide the AB Alive tally, by the total number of dissected berries

and multiply it by a hundred.

And for % CD, divide the CD tally, by the total number

of dissected berries and multiply that by 100.

These numbers will give you a snapshot of CBB on your farm

and help you determine if is a good time to spray.

The higher the percent infestation and or AB Alive is,

the more likely you'll need to spray.

The higher the percent CD is,

the more likely your spray application was late

or requires modification for great of effectiveness.

To help you with your spray decision,

you can use Table 1 on the worksheet as a guide.

Start by finding your percent infestation on the right hand column.

Then, on the top row, find your percent AB Alive.

Next, see where they intersect

and find the number or color in the legend and review the recommendation.

Please note, Table 1 may differ from your spray thresholds

and you should adjust it accordingly.

If you do decide to spray, spray immediately

when weather conditions are favorable.

Also, make sure to save your completed worksheet for future reference.
