Background: Bacterial diseases in cultured fish are considered the main problem to aquaculture system. Skin is the structure that covers the body in fish. Skin histopatological alterations were used to assess the effects of Aeromonas hydrophila exposure on the yellowfin seabream )Acanthopagrus latus(. Methods: In this regard, 90 A. latus were exposed to sublethal concentrations of A. hydrophil...

Fishes surveyed for parasites.

The broad mite (Polyphagotarsonemus latus (Banks)) is an important pest in many crops, including azalea (Rhododendron simsii Planch. hybrid). Broad mites cause the malformation of shoot tips, leaves and flowers azalea. It known that jasmonic acid (JA)- salicylic (SA)-dependent signaling pathways are related to presence herbivorous mites. Here, we describe levels two main plant defense-related h...

Rhinocyllus conicus, a weevil introduced for biological control of exotic weeds, has had major nontarget ecological effects on native thistles. Some practitioners have argued that this is an isolated case. We report, however, that another Eurasian weevil (Larinus planus), currently being distributed in North America for the control of Canada thistle (Cirsium arvense), is significantly reducing ...
