| Abstract: | Pyemotes scolyti (Oudemans,1936) ,a new record species from China,is an efficient parasite of Scolytus japanicus Chapuis and 5. seulensis Murayamy both of that seriously damage drupe trees. Its male and females pass through all immature stages while still within physogastry (a swelling opisthosoma) of the mother mite and are born as adults. There are continuous generation produced throughout the warmer months. The average number of the offspring laid per female is 60,sexual rate is:30:1 -2. They may be used in biological control. |
