BIMCO advises members to check clauses as Asian gypsy moth season starts


The Asian gypsy moth (AGM) flight season is just around the corner. BIMCO advises its members to pay attention to the possible consequences of calling at ports where the AGM is indigenous or established.


Not all countries have introduced the new name yet, but BIMCO has decided to standardise on Flighted Spongy Moth Complex, abbreviated to FSMC.

Members need to be aware if calling ports in the following countries:

  • Russian Far East
  • China
  • Republic of Korea/Democratic Peoples Republic of Korea
  • Japan
  • Vietnam

Please be aware the list only serves as a guidance, and therefore, confirmation or changes should be gathered from the port agent.<

AGM is subject to spread like a wildfire unless active efforts are made to contain the spread. If allowed, the AGM will spread to areas where it’s not indigenous and cause great damage to agriculture and forestry and associated commerce. Calling above mentioned ports in the high-risk season will make the vessel subject to inspection in other areas of the pacific region, notably:

  • Canada
  • USA
  • New Zealand
  • Australia
  • Chile

If the vessel is found to be infested by AGM, authorities can order the vessel out of territorial waters thereby affecting the revenue of the vessel.


AGM is attracted to light, and as such the eggs will usually be found on parts of the vessel subject to lumination. The egg mass can easily be scraped off and destroyed using either alcohol, boiling water or incineration. After the eggs hatches, the larvae eats vegetation, primarily leaf, before entering the pupae stage for another 10-14 days. Finally, the moth stage will last 2-3 weeks, during which the only purpose is to mate and lay eggs. The male moth dies after mating, while the female dies after laying eggs.

Subject to the local climate, the final moth stage of AGM will be in the period from end May through September, according to the table below, supplied by the North American Plant Protection Organization:

Country Risk Area Specified Risk Period 
Russian Far East South of 60o North and west of 147o longitude (excluding those ports on the Kamchatka Peninsula) July 1 to September 30
China North of latitude of 31o 15' N June 1 to September 30
Republic of Korea In all areas June 1 to September 30
Japan – Northern In prefectures of Hokkaido, Aomori, Iwate, Miyagi, Fukushima July 1 to September 30
Japan –Western In prefectures of Akita, Yamagata, Niigata, Toyama, Ishikawa June 25 to September 15
Japan – Eastern In prefectures of Fukui, Ibaraki, Chiba, Tokyo, Kanagawa, Shizuoka, Aichi, Mie June 20 to August 20
Japan – Southern In prefectures of Wakayama, Osaka, Kyoto, Hyogo, Tottori, Shimane, Okayama, Hiroshima, Yamaguchi, Kagawa, Tokushima, Ehime, Kochi, Fukuoka, Oita, Saga, Nagasaki, Miyazaki, Kumamoto, Kagoshima June 1 to August 10
Japan – Far Southern In prefecture of Okinawa May 25 to June 30
