✦ Synopsis
The pygmephoroid mite, Brennandania lambi (Krczal), is the most serious mite pest of mushroom production in Shanghai. China. This mite could not develop and reproduce on the mycetia of Lentinus edodes, Flammulina velutipes, Pleurotus ostreatus or Pleutotus sajor-caju, but 12-20% of the females survived 15 to 31 days on these hosts, whereas all mites died after 8 days in absence of food.
When fed the mycelia ofAuricutaria polytricha, B. lambi adults could become gravid and reproduce but active larvae failed to develop to the next stage. B. lambi developed and reproduced on the mycelia of Auricularia aurictda, Hericium erinaceus, Tremella fiwiformis and Agaricus bisporus. Mobile stages ofB. tambi damage A. bisporus by feeding on its mycelia. Field surveys of mite damage during 1983-1989 in the suburbs of Shanghai revealed that contaminated spawn was the major source of the mite problem and losses of the crop averaged between t0% and 20%. Experiments on the effects of temperature on mite survival indicate that exposure of mites at StY C for 1 hour or -10 ° C for 24 hours killed all stages ofB. lambi. Thus, heating treatment during well-executed phase II cornposting and freezing of mushroom spawn at -10 ° C for 24 hours should eliminate or at least reduce the damage to mushrooms by this pest.
