There are several obstacles in cocoa cultivation, one of which is the low level of productivity. The low level of productivity is caused by many factors, one of which is the presence of pest. One of the main pests on the cocoa plant is the cocoa pod sucker (Helopeltis sp.). This study aims to determine population density and intensity of the cocoa pod sucker (Helopeltis sp.) On cocoa (Theobroma cacao L.) in several districts in East Lampung Regency. This research was conducted in September 2018, conducted in three sub-districts in East Lampung Regency. This research method was carried out by survey, by directly observing Helopeltis spp. existing in each sample plant. The results showed that the population density of Helopeltis sp. in Margatiga District, 0.19 head / fruit, 0.06 head / fruit in Sukadana District, and 0.16 head / fruit in Sekampung Udik. The population density of Helopeltis sp. in the three sub-districts there is no significant difference. The intensity of damage to cocoa pods in Margatiga District was 45.58%, 22.00% in Sukadana District, and 22.42% in Sekampung Udik District.
