| description | <i>Halyomorpha halys</i> (Hemiptera: Pentatomidae), native to East Asia, has become a globally invasive pest, as a serious threat to agricultural production and a notorious nuisance pest in urban areas. Considerable efforts have been made so far to develop effective pest control measures to prevent crop damage. Biological control of this invasive stink bug by egg parasitoids has proven to be the most environmentally sustainable long-term solution. Knowledge of the native egg parasitoid fauna is of key importance when implementing a biological control program. Therefore, the main objective of our study was to detect egg parasitoid species associated with <i>H. halys</i> in the Goriška region (Western Slovenia) and to evaluate their impact on the pest population under field conditions. In the years 2019 and 2020, around 4600 <i>H. halys</i> eggs were collected in the wild and more than 3400 sentinel eggs were exposed to detect parasitoids in the field. Five egg-parasitoid species emerged from <i>H. halys</i> eggs: <i>Anastatus bifasciatus</i> (Hymenoptera: Eupelmidae), <i>Telenomus</i> sp., <i>Trissolcus basalis</i>, <i>Trissolcus mitsukurii</i> (Hymenoptera: Scelionidae) and <i>Ooencyrtus telenomicida</i> (Hymenoptera: Encyrtidae), all of them are new records for Slovenia. The native species, <i>An. bifasciatus</i>, dominated in urban and suburban areas, while non-native <i>Tr. mitsukurii</i> prevailed in agricultural areas. Overall parasitism rates of naturally laid eggs by the parasitoid species complex in 2019 and 2020 was 3.0 and 14.4%, respectively. Rapid recruitment of native parasitoids, early detection of an effective alien parasitoid species and increasing overall parasitism rates are very encouraging results, which need to be followed and verified in future research. |
