| Abstrak This study aims to establish the influence of shade and littered to number of types, population, intensity of attacks and the population of predators Helopeltis spp. Which was the central cacao plate plantations in the napu valley. The study is held in January to March 2018 in the village of Watumaeta, Banyusari, Wuasa, and Kaduaa, town lore north of Poso county, central Sulawesi. On this research is based on a random design group (RAK) a factorial pattern consisting of two factors. The first factor is a percentage of shade (N) consisting of two levels: N1 = 0-40% and N2 = 60-100%, the second factor was serized (S) on cacao environments consisting of two factors: S1 = servent with an density of 1 tons and S2 = serasset with 4 tons density with 4 treatment combinations, each match repeated 4 times, resulting in 16 unit experiments. Influence treated is further tested with honest's real test (BNJ) extent of 0.05%. Identification found that the species of helopeltis spp. Found two species of inhabits of cacao plantations in the Napu valley helopeltis antonii signorethelopeltis and theivora waterhouse. The highest helopeltis spp. Population is at the nymph stage in the treatment of the 6 ton literred / plot (S2) on palm observation to eight, 5.68 individual / tree whereas at its phase in imago on the littered 6 tons / plot (S2) week to eight is 5.09 individual / tree. Percentage of the attacks intensity of helopeltis spp. The eastern attacks are modern as the eastern attacks of literred 6 tons / plots (S2) to six with a percentage of 32.91%. Presentation of the population of predators helopeltis spp. Highest with his attacks level in treatment of literred 6 tons (S2) on the week of observation of the four 127.3 individuals / plot. |
