摘　　要：Termites are social insects that inhabit colonies in the soil. Termites feed on a wide range of plants found within diverse habitats of Luanda Sub-County. This study aimed at assessing feed preference of edible termites and analyzing their phytochemical composition. Termites were exposed to ten different test plants in their natural habitats to assess feed preference. Forty-seven study sites were selected as they had high termite abundance from previous studies. The test plants were <i></span><i><span style="font-family:Verdana;">Grevillea robusta</i></span></i><span style="font-family:Verdana;">, sugarcane, maize, blue citronella grass, <i></span><i><span style="font-family:Verdana;">Eucalyptus</i></span></i><span style="font-family:Verdana;">, mango, avocado, neem, bamboo and a mixture of all the ten plants. Small pits were dug in the ground where the ten treatments were placed and replicated four times each. The test plants were placed in the evening then covered with soil block. The number of termites feeding on the test plants was counted after 12 hours the following day. There were separate trials for crushed and uncrushed feed substrates. The feed substrates that showed high feed preference was selected for phytochemical analysis. The plants whose crude extract was obtained were </span><i><span style="font-family:Verdana;">Grevillea robusta,</span></i><span style="font-family:Verdana;"> bamboo, <i></span><i><span style="font-family:Verdana;">Eucalyptus</i></span></i><span style="font-family:Verdana;">, cypress, maize and sugarcane. The results for this study were analysed using one-way ANOVA. The study revealed that crushed feed substrates had a high level of feed preference by termites p < 0.05. The mixture of all the feed substrates also showed high termite preference and a mean and SE of 676.500 ± 41.7^{</span>^{<span style="font-family:Verdana;">a</span>}<span style="font-family:Verdana;">}.
