Abstract
Cocoa is one of the plantation commodities that are the mainstay of the economy in Indonesia. However, the fact is that cocoa production in Indonesia continues to decline. One of the causes of the decline in cocoa production in Indonesia is due to the attack of Helopeltis sp. The attack of Helopeltis sp. on cocoa resulted in a decrease in production up to 50% and an increase in production costs up to 40%. Therefore, to minimize the damage caused by Helopeltis sp. control measures must be taken. If we have information or knowledge about the activity of pest, control will be more effective and targeted. Observations were made directly and using focal animal sampling method. Observations were carried out in three time periods, namely in the morning (06.00 - 08.30 WIB), afternoon (10.00 - 12.00 WIB) and afternoon (13.00 - 15.00 WIB). Parameters in this observation include the activity of visiting Helopeltis sp., time of visit and observing the presence or absence of Helopeltis sp. who visited the cacao flower. The result is Helopeltis sp. shows the duration and time of the most active visit in the morning and there is no Helopeltis sp. who visited the cacao flower.
