An acarid mite,Tyrophagus putrescentiae (Schrank), was found to feed on southern corn rootworm (SCR) eggs in peanut and corn agroecosystems. In laboratory studies,T. putrescentiae eggs were generally oviposited directly on SCR eggs, and immatures fed only on previously damaged SCR eggs, depending upon adults to penetrate the chorion of SCR eggs. Individual adultT. putrescentiae significantly reduced (P<0.05) the number of larvae to eclose from 40 SCR eggs. Initial population levels of 1, 2, 5… CONTINUE READING
