A method for counting the natural enemy Holcothorax - a parasitoid of the apple leaf miner


, : A method for counting the natural enemy Holcothorax - a parasitoid of the apple leaf miner. Sel' skokhozyaistvennaya Biologiya ( 5): 103-105

The suitability of coloured sticky traps for monitoring the abundance of Holcothorax testaceipes, a parasitoid of the apple pest Lithocolletis pyrifoliella (Phyllonorycter pyrifoliella), was studied in the Voronezh region of Russia. Yellow sticky traps were shown to be the most effective.

The suitability of sticky color traps for the calculation of holcotorex, parasitizing the apple leaf miner, has been studied. Yellow traps have been found to be most efficient for this purpose. A strong correlation (r = 0,96) has been observed bet...

The relative abundance of P. blancardella (F.) and P. crataegella (Clemens) was examined on sprayed and unsprayed apple trees in Connecticut by identifying pupae collected from fallen leaves during the 3rd leafminer generation of 1980-1982. P. cra...
