神戸市 18日に「ヒアリ」対策本部を設置

先月、神戸港で荷揚げされたコンテナから強い毒を持つ外来種のアリ「ヒアリ」が見つかりましたが、新たに約100匹が見つかりました。

今回、見つかったヒアリは体長が2.5ミリから6ミリ程度です。刺されると激しい痛みや発熱などを引き起こし、体質によってはアレルギー性のショックで死亡する恐れもあります。
先月、中国から神戸港に到着したコンテナの中で大量のヒアリが見つかったことを受けて、今月、環境省や神戸市が周辺を調査しました。
その結果、コンテナ置き場のアスファルトの亀裂からヒアリ約100匹が見つかり、市がすべて駆除したということです。
ヒアリは女王アリが卵を産んで繁殖しますが、神戸市によりますと、今回、見つかったなかに女王アリはいなかったということです。
神戸市は18日、「ヒアリ」対策本部を設置し、市民に対処方法や情報提供を呼び掛ける方針です。

Queen

Fire ant queens, the reproductive females in their colony, also are generally the largest. Their primary function is reproduction; fire ant queens may live up to 7 years and can produce up to 1,600 eggs per day, and colonies will have as many as 250,000 workers.^[10][12] The estimated potential life span is around 5.83 to 6.77 years.^[13] Young, virgin fire ant queens have wings (as do male fire ants), but they rip them off after mating.

Males (drones)

Males mate with the queen. They die soon after mating.

Other roles

There are other types of roles in an ant colony like the workers and the soldier ants. The soldier ants are known for their larger and more powerful mandibles while the worker takes care of regular tasks (the main tasks in a colony are caring for the eggs/larvae/pupae, cleaning the nest, and foraging for food).^[10] However, Solenopsis daguerrei colonies contain no workers, as they are considered social parasites.^[14]



Solenopsis daguerrei is a species of parasitic ants native to Argentina and Uruguay .^[1] The young queens of the species invade the nests of other species, such as the red imported fire ant (RIFA) (Solenopsis invicta). This is made possible by the fact that the S. daguerrei queen produces pheromones which are very similar to those produced by the queens of the host species. The young queen finds a queen of the host species and latches onto it, eating the food intended for the host queen and slowly killing it. The S. daguerrei queen then begins laying eggs. These are taken care of by the host ants, sometimes preferentially to their own brood. S. daguerrei only produce winged virgin queens and males. No workers are needed, since these are provided by the host species. The winged ants fly off to mate and invade new colonies.
