Monochamus Notatus

Females of both Monochamus scutellatus (Say) and Monochamus notatus Drury (Coleoptera: Cerambycidae) preferred to oviposit in large diameter pine logs. When females of both species were present, oviposition on the largest diameter log by M. scutellatus was much reduced. There were both inter- and intra-specific contests among females, usually over oviposition holes cut by females in the bark. Contests among females occurred disproportionately on the largest logs. Previously inseminated females paired with radiation-sterilized males laid no fertile eggs, supporting the hypothesis that a male is highly likely to fertilize eggs laid by a female with which he is paired. In intraspecific contests among females over oviposition holes and among males over females, a challenger could supplant a resource holder only in an escalated contest. However, in interspecific contests, M. notatus challengers were able to supplant M. scutellatus resource holders without escalation. In both sexes, a contest was more likely to be nonescalated when the resource holder was larger than the challenger. Among males, a larger resource holder was significantly more likely to repel a smaller challenger than was a larger challenger to replace a smaller resource holder.

Kecoa merupakan serangga yang suka hidup ditempat terlindung, tertutup maupun lipatan-lipatan sehingga susah diberantas, akan tetapi serangga tersebut mempunyai alat komunikasi yang  digunakan untuk memanggil sesamanya untuk berkumpul yang disebut aggregation pheromone. Aggregation pheromone ini diteliti untuk dimanfaatkan sebagai salah satu cara pengendaliannya. Pada penelitian ini aggregation pheromone diteliti dengan mengekstrak kotoran kecoa dengan berbagai macam pelarut dan hasil ekstraknya diuji secara biologi ditunjukkan dengan banyaknya kecoa yang datang dan berkumpul pada ekstrak AP tersebut. Dalam penelitian ini pelarut methanol merupakan pelarut yang paling baik dalam ekstraksi AP yang ditunjukkan adanya 80% kecoa yang datang berkumpul. Dari ekstraksi tersebut setelah dianalisa dengan alat kromatografi gas diperoleh senyawa aktif yang merupakan Aggregation pheromone dari kecoa Periplaneta americana L.  Senyawa tersebut diduga periplanon A dan periplanon B dengan waktu retensi 25,417 menit dan senyawa B dengan waktu retensi 27,007 menit.

Ethanol and sulcatol (6-methyl-5-hepten-2-ol), primary attractant and population aggregation pheromone, respectively, for Gnathotrichussulcatus, were deployed alone or in combination in traps at 10 locations in a commercial sawmill at Chemainus, B.C. The traps were in operation for the last week of the months, April through October 1974, and caught 3098 beetles. Sulcatol was the only significant treatment. Traps baited with it alone or in combination with ethanol caught over 98% of the beetles. There was no significant interaction between ethanol and sulcatol. There was a distinct bimodal seasonal trend in numbers of beetles caught. Locations with the greatest catches of beetles were those where unseasoned lumber was stored, which suggests that beetles either emerged from and (or) oriented to such lumber.
