Preovipositional stinging of an external parasitoid, Euplectrus kuwanae Crawford (Hymenoptera: Eulophidae).

Response of Natural and Factitious Hosts to the Ectoparasite Euplectrus plathypenae (Hymenoptera: Eulophidae)

Antennal Sensilla of Tamarixia radiata (Hymenoptera: Eulophidae), a Parasitoid of Diaphorina citri (Hemiptera: Psyllidae)

Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) is an effective idiobiont ectoparasitoid of the psyllid Diaphorina citri Kuwayama (Hemiptera: Psyllidae), vector of the huanglongbing (citrus greening disease) pathogen. We examined the external and functional morphology of the antennal sensilla of adultmale and femaleT. radiatabyusing scanning and transmission electron microscopy, respect...

Oogenesis pattern and type of ovariole of the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae).

The knowledge on ovigeny in parasitoids is important for basic studies on physiology and applied biological control. The ovigeny pattern and type of ovariole of the parasitoid Palmistichus elaeisis Delvare & LaSalle (Hymenoptera: Eulophidae) were studied in newly-emerged females at seven, 14, 24 and 48 h intervals after their emergence from Tenebrio molitor L. pupae (Coleoptera: Tenebrionidae)....

A new parasitoid of the Erythrina Gall Wasp, Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae)

Aprostocetus exertus La Salle (Hymenoptera: Eulophidae: Tetrastichinae) is described as a parasitoid of the invasive Erythrina Gall Wasp, Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae: Tetrastichinae). The description is based on material originally collected in Tanzania and South Africa. This species is described because of its potential as a biological control agent against the Erythr...

Offspring production and development in the parasitoid wasp Melittobia clavicornis (Cameron) (Hymenoptera: Eulophidae) from Japan

The development time, sex ratio and offspring production of Melittobia clavicornis reared with wild, facultative and factitious hosts are presented. Known hosts and different biological aspects presented in previously published reports are summarized and clarified. Immature development time was equivalent or slightly longer than that of other Melittobia species, and the sex ratio was approximat...
