Typhlodromus pyri<br />

strain resistant to<br />

organophosphates<br />

Panonychus ulmi,<br />

* + means effective, - means not effective bio<strong>control</strong> agent.<br />

Italy Inoculative Field + Different colonization patterns on<br />

three grape varieties (with<br />

different pubescent leaf<br />

undersurfaces).<br />

The high competitiveness of K.<br />

aberrans over the other 2<br />

phytoseid species is a major<br />

factor in selecting predatory<br />

species for inoculative releases.<br />

Japan Inundative Field<br />

(grape in<br />

green<br />

house)<br />

+ Release of P. persimilis onto the<br />

grass ground cover in the spring.<br />

No chemical <strong>control</strong> was<br />

required.<br />

Veneto, Italy Inoculative Field (A) + Releases were successful <strong>and</strong> the<br />

predators became more abundant<br />

on the variety with pubescent leaf<br />

under-surface.<br />

Native A. <strong>and</strong>ersoni were<br />

displaced by T. pyri.<br />

Field (B) + Two grape varieties with different<br />

leaf hair density.<br />

T. pyri colonization failed; K.<br />

aberrans was more successful on<br />

glabrous varieties. K. aberrans<br />

displaced native P. finitimus.<br />

Ontario,<br />

Canada<br />

North-eastern<br />

Italy<br />

Inoculative Field + T. pyri out-competed native<br />

Amblyseius fallacies.<br />

T. pyri is an effective bio<strong>control</strong><br />

agent <strong>and</strong> may be introduced by<br />

transferring leaves.<br />

Inoculative Field 15-years observations. The<br />

predator colonized the vineyard<br />

<strong>and</strong> competed successfully with<br />

other species.<br />

Role of alternative foods, leaf<br />

morphology <strong>and</strong> selective<br />

pesticides.<br />
