The quant ty of sp ders n the B ocontrol area wh ch only m crob olog cal nsect c des were used was no d fference from the quant ty of sp ders n naturalcontrol area; the quant ty of sp ders n the coord natedcontrol area wh ch such as ch t n synthet c nh b tor were ma nly used de creased s gn f cantly compar ng to the quant ty of sp ders n naturalcontrol area, but was much r cher than n chem calcontrol area wh ch w despectrum chem cal nsect c des were ma nly used; the quant ty of sp ders n chem calcontrol area was least,was about 1/ 3 of the quant ty of sp ders n naturalcontrol area.
