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.

Population Aggregation

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.

Volatile Production

The Annonaceae fruits weevil (Optatus palmaris) causes high losses to the soursop production in Mexico. Damage occurs when larvae and adults feed on the fruits; however, there is limited research about control strategies against this pest. However, pheromones provide a high potential management scheme for this curculio. Thus, this research characterized the behavior and volatile production of O. palmaris in response to their feeding habits. Olfactometry assays established preference by weevils to volatiles produced by feeding males and soursop. The behavior observed suggests the presence of an aggregation pheromone and a kairomone. Subsequently, insect volatiles sampled by solid-phase microextraction and dynamic headspace detected a unique compound on feeding males increased especially when feeding. Feeding-starvation experiments showed an averaged fifteen-fold increase in the concentration of a monoterpenoid on males feeding on soursop, and a decrease of the release of this compound males stop feeding. GC-MS analysis of volatiles identified this compound as α-terpineol. Further olfactometry assays using α-terpineol and soursop, demonstrated that this combination is double attractive to Annonaceae weevils than only soursop volatiles. The results showed a complementation effect between α-terpineol and soursop volatiles. Thus, α-terpineol is the aggregation pheromone of O. palmaris, and its concentration is enhanced by host-plant volatiles.
