<p class="5abstrak"><em>Papilio</em><em> blumei</em> is an endemic butterfly of Sulawesi and especially in Bantimurung Bulusaraung National Park. This research was to observed of the behaviour and natural enemies of <em>P. blumei</em> in Bantimurung Bulusaraung National Park. The behaviour of the insect were mating, foraging, competiting, ovipositing and mud-puddling. Life table was used for analysis of mortality factors, therefore the number of mortality was analyzed by key-factors formulation. The result indicated that mating strategies is patrolling. Foraging activity of the sixth instar was the highest compared to the other instars and the lowest one activity of the prapupa stadium of <em>P. blumei</em>. Nectar host plants for the imago of butterfly were <em>Sarcosephalum latifolius</em> and <em>Eugenia sp</em>. There was <em>Scudderia sp</em>. as an interspesific competitor for larval <em>P. blumei</em>. The intraspesific competitor of the imago stage was male of <em>P. blumei</em>. Female <em>P. blumei</em> laid eggs on abaxial leaf <em>E.hupehensis</em> and the eggs hatched after six days. The larva of  <em>P. blumei</em> has a overheating behaviour and the adults has a mud puddling. The natural enemies of <em>P.blumei </em>is <em>Trichogramma</em> sp., with k value = 0.381, <em>Pteromalus </em>sp., with k value = 0.125 and <em>Formica </em>sp., with k value = 0.096.</p>

AbstractThe diamondback moth (DBM, Plutella xylostella L. (Lepidoptera: Plutellidae)) consumes a wide variety of brassicaceous host plants and is a common pest of crucifer crops worldwide. A highly unusual infestation of a sugar pea crop was recorded in Kenya in 1999, which persisted for two consecutive years. A strain (DBM-P) from this population was established in the laboratory and is the only one of several strains tested that can complete larval development on sugar peas. The oviposition acceptance and preference of the DBM-P strain was assessed in the presence of cabbage plants, sugar pea plants or both, in comparison to another strain (DBM-Cj) that was collected from cabbage and is unable to grow on pea plants. As expected, DBM-Cj females preferred to oviposit on cabbage plants. Surprisingly, DBM-P females also laid most eggs on cabbage and very few on peas. However, they laid significantly more eggs on the cabbage plant when pea plants were present. Our findings suggest that DBM-P manifested the initial stages of an evolutionary host range expansion, which is incomplete due to lack of oviposition fidelity on pea plants.
