Native and naturalized mealybug parasitoids fail to control the new citrus mealybug pest Delottococcus aberiae por Tena, Alejandro, Garcia-Bellon, Jesus, Urbaneja, Alberto

“…However, only three specimens were recovered when A. pseudococci was released in three heavily infested citrus orchards. A subsequent semi-field assay indicated that this parasitoid and A. angustifrons suffered high encapsulation rates when the mealybug was settled on trees. …”

An autoparasitoid wasp, inferior at resource exploitation, outcompetes primary parasitoids by using competitor females to produce males por Marrao, Rosalina, Frago, Enric, Pereira, José A., Tena, Alejandro

“…Using field data from 40 olive orchards, this study examined the mechanisms that regulate: (I) the interspecific competition between primary parasitoids of the genus Metaphycus and the autoparasitoid Coccophagus lycimnia; and (II) the density of their shared herbivore host, the soft scale Saissetia oleae. 3. …”
