Standard GB 9194-88 for the Control of Tea Geometrid
This standard applies to the control of the tea geometrid (Boarmia obliqua hypulina Wehrli) in mature plucking tea gardens. 1 Terms and definitions 1.1 Control threshold The pest population density at which, under the specified optimal control period, the incremental economic loss equals the incremental cost of preventing that loss. 1.2 Infestation center Larvae hatched from the same egg mass gather on the same plucking surface to cause damage. One aggregation point constitutes one infestation center. 2 Control
