In this paper, we describe two new species of dajid isopods found enveloping the antennules decapod hosts: Akrophryxus acinaces sp. nov. parasitizing Pycnoplax surugensis (Rathbun, 1932) (off Pacific coast central Japan, approximately 200 m depth) and A. pallipalicus Parapalicus armatus Castro, 2000 (South China Sea, 410 depth). Females both exhibit characteristic spheroid shape in genus Willia...

Detecting the presence and amount of a fungus in leaf tissue, especially when it is suspected that other fungi are presen~, is quite difficult. Culture methods can be unreliable because a few spores of a fast growing fungus may overgrow other fungi within a, few days (e.g. McKENZIE and HUDSON 1976). Methods which measure the chitin content of fungal walls cannot differentiate between fungi; in ...

Laboratory, greenhouse and field studies were conducted on Oomyzus sokolowskii Kurdjumov, a parasite of diamondback moth, Plutella xylostella (L.), to judge its suitability for introduction in the field to control the plutellid. Oomyzus sokolowskii preferred the third and fourth instar diamondback moth larvae over fresh pupae for parasitization. It is thus a larval parasite. Within the range of...
