Abstract:
The study was conducted at Belis, Caliking, Atok, Benguet in a field where coffee trees had been standing for 19 years with coffee berry borer infestation from October 2015 to January 2016 to determine the infestation of coffee berry borer, to establish appropriate number of lure traps per number of trees, to determine the percent damage of coffee berry borer during harvest, to know the longevity of the lure content, to identify possible source of the next generation of coffee berry borer, to identify sibling species of coffee berry borer acaught in the lure trap and to record other species of insects caught in the lure traps.
The coffee berries were already infested with coffee berry borer before the traps were set.
The use of three lure traps per 20 coffee trees caught the highest population of coffee berry borer and increasing to four and five lure traps reduced the number of damaged harvested berries.
The use of four and five lure traps had the lowest percent damage on harvested coffee berries.
The attracting capacity of the lure mixture ranges from 19 days to 22 days.
There was an emergence of female coffee berry borer from the fallen berries collected from the ground after harvest.
Sitophilus granaries Linnaeus or the grain weevil, a pest of stored grains, was attracted by the lure trap.
Other insects caught in the trap were Dendrophagus crenatus Paykull, suspected predator of CBB, Stelidota coensa Erichson and Agallia constricta Van Duzee, Grammodes geometrica Fabricius, which are general pests of other crops, Philonthus tenuicornis Mulsant and Rey and Camponotus pennsylvanicus (DeGeer), both general predators of insects, Aedes aegypti (Linnaeus), pest to humans, Drosophila melanogaster Meigen, a sacavenger and Diadegma semiclausum Helen, a parasitoid of Diamond-back moth.
