Germany Inundative Field + 3 months after application an increase of<br />

the M.a. density in soil was observed.<br />

Compared with untreated plots a lower<br />

infestation was observed in the M.a.-<br />

treated plots. Two years after treatment a<br />

<strong>control</strong> effect was still observed whereas<br />

the density of M.a. in soil decreased.<br />

Three years after treatment no effect on<br />

the pest was detectable <strong>and</strong> the M.a.<br />

density had decreased to a value similar<br />

to that in the <strong>control</strong> . A periodically<br />

application is necessary.<br />

+ Susceptibility of V.p. 1st-instar<br />

larvae. Augmentation of nematode<br />

populations during the critical<br />

period of V.p. oviposition <strong>and</strong><br />

eclosion is suggested as a <strong>control</strong><br />

technique.<br />

H. bacteriophora: reduced survival<br />

of attached phylloxera by up to<br />

80%.<br />

S. glaseri had no measurable impact.<br />

No evidence that H.b. could<br />

successfully reproduce within the<br />

bodies of the hosts.<br />

Augmentative use in the field in an<br />

release programme may be<br />

constrained by the need to use high<br />

densities, their dependence on moist<br />

soils, <strong>and</strong> their inability to propagate<br />

themselves within hosts.<br />
