“…This rate is higher than that normally expected for aphelinids (Williams and Polaszek 1996;De Barro et al 2000). There has been increasing interest in using biological control through conservation of native natural enemies (Castane et al 2004). This interest in native natural enemies is emphasized by present questioning of releasing exotic natural enemies may carry with it an important risk of aVecting non-target organism (Ehler 2000).…”

EYcient use of parasitoids in pest control depend on the knowledge of the biological relationships between host and parasitoid. Eretmocerus mundus Mercet (Hymenoptera: Aphelinidae) is one the most important natural enemies of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) that is found in Welds and greenhouses in Adana, Turkey. Although more studies have been done to determine the relationships between E. mundus and B. tabaci, the diVerences among strains of E. mundus could have important biological concequences. In this study, biological characteristics of native population of E. mundus parasitization of B. tabaci (Q biotype) were determined using bean plants Phaseolus vulgaris (L.) at a constant temperature of 25 § 1°C, relative humidity 70 § 10% and 16:8 (L:D) photoperiod regimen. All B. tabaci nymphal instars were parasitized by E. mundus, but the mean number of daily-parasitized nymphs was highest in the second instars (15.3). In addition, second instar females had the shortest mean development time (15.2 days). Mean development times of parasitoids obtained from Wrst, second, third and fourth B. tabaci instars varied from 15.2 to 16.2 days and 15.2 to 15.9 days for female and male, respectively. Proportion of female ($/#+$) varied from Wrst (0.53) to second (0.34) host instars. Impact of results on potential biological control of B. tabaci was discussed through conservation native natural enemies.

“…It also reports a potential adverse effect of D. hesperus on E. formosa . However, two recent greenhouse studies indicated that D. hesperus did not have a disruptive effect on whitefly biological control while used in combination with E. formosa (Castañ é et al 2004;McGregor & Gillespie 2005). Compatibility of the fungus with the predator and the parasitoid therefore remains to be tested in complementary greenhouse studies.…”

The development of effective biological control programs in which predators are integrated with other natural enemies such as parasitoids and entomopathogens requires an understanding of their interactions. In this study we examined the extent to which the omnivorous mirid bug Dicyphus hesperus , an effective biological control agent of greenhouse whiteflies, accepts prey that are either parasitized by the specialist whitefly parasitoid, Encarsia formosa or infected by the generalist fungal entomopathogen, Beauveria bassiana . In non-choice laboratory experiments, we measured how parasitism and infection of greenhouse whitefly, Trialeurodes vaporariorum , as related to parasitoid age and course of fungal infection, might alter the probability of feeding by second instar or adult female predators. Predation by D. hesperus was similar for parasitized and unparasitized whiteflies, regardless of parasitoid age. However, predators generally avoided feeding on infected whiteflies, particularly when infection was manifested through the presence of oosporein or hyphae on the surface of prey.

“…Como resultado, los esfuerzos para controlar la mosca blanca de T. vaporariorum en el invernadero a lo largo de la costa al noreste de España usando Encarsia formosa (Gahan) (Hymenoptera: Aphelinidae) en tomates de primavera sufren invasiones periódicas de la mosca blanca que limitan la efectividad del parasitoide (Albajes y Alomar, 1999). En esta situación en la que rara vez se aplican insecticidas al cultivo, los enemigos naturales nativos, como los depredadores míridos M. pygmaeus y D. tamaninii, también invaden los invernaderos (Castañé et al, 1987;Castañé, Alomar y Riudavets, 1997;Castañé et al, 2004). Esta migración de fitófagos hacia los invernaderos es común en la región mediterránea y se ha documentado en Italia, Grecia y Francia, y también en zonas con clima atlántico suave, como las Islas Canarias y Portugal (Malausa, Drescher y Franco, 1987;Perdikis y Lykouressis, 1996, 2000, 2004aTavella et al, 1997;Carvalho y Afonso, 1977).…”

“…No se observó ninguna preferencia por pupas parasitadas en las muestras bajo condiciones de invernadero, mientras que los estudios de laboratorio revelaron una marcada tendencia a evitar las pupas de los parasitoides. En esta área, los progra-mas de IPM para los tomates bajo condiciones de invernadero y otras hortalizas deberían aprovechar la presencia de este complejo depredador y permitir la inmigración y el establecimiento de poblaciones sin afectarlos con insecticidas no selectivos (Castañé et al, 2004).…”
