These are count of metcalfa colony at 0 DaysAfterTreatment (=> before trt),
2,
7 and 14 DAT (=>three column of data after treatment)

First column  contain  the number of the treatment
1=>check
2=>experimental insecticide @low rate
3=>experimental insecticide @normal rate
4=>experimental insecticide @double rate
5=> Standard insecticide

Second column contain progressive number of plot (randomized treatment)
Third column contain progressive number of each sub sample.
So
how can I perform pre-post control following Henderson-Tilton formula that is

(1-(insect_in_control_before_trt * insect_in_treatment_after_trt) /
((insect_in_control_after_trt * insect_in_treatment_before_trt))*100

so can anybody suggest me how can I sum every sub sample by each plot(20 data
per column) and perform H-T formula?

or ABBOT

100*(1-(insect_in_treatment_after_trt / insect in control after trt)


tnx in advance
