Zusammenfassung: | In the Mediterranean climate experienced at Camposano, near Naples, Globodera tabacum completed almost five generations on egg-plant during the period 29 May - 23 October, 1996. A reproduction rate (ratio between initial and final densities of eggs and juveniles in cysts in the soil) of 96.1 was recorded in September during the fourth generation. However, at the end of the investigation the equilibrium density was 1.4 eggs and 1.9 encysted juveniles per cm*[3) of soil
[In clima mediterraneo, a Camposano, vicino a Napoli, Globodera tabacum ha completato quasi cinque generazioni su melanzana nel periodo 29 maggio - 23 ottobre 1996. In settembre, nel corso della quarta generazione, e' stato registrato un tasso di riproduzione (rapporto fra le densita' iniziali e finali di uova e larve nelle cisti nel terreno) di 96.1. Comunque, alla fine dell'indagine, la densita' all'equilibrio era di 1.4 uova e 1.9 larve incistate per cm*[3) di terreno] |
