The pest status of diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Yponomeutidae), in South Africa is lower than in other countries with similar climates. A project was initiated to investigate possible reasons for this. Larval and pupal populations of DBM were monitored weekly for two years on unsprayed cabbage plots. Adult populations were also monitored continuously for two ye...

The first findings of egg-parasitoids of the invasive planthopper Ricania speculum (Walker) (Hemiptera Ricaniidae) are presented. Aprostocetus (Ootetrastichus) crino (Walker) (Hymenoptera Eulophidae), a native species until now only associated with Oecanthus spp. (Orthoptera Oecanthidae) eggs, was the most common. Chaetostricha similis (Silvestri) (Hymenoptera Trichogrammatidae) and Polynema sp...

Adults and immatures of Diaphorina teucrii sp. nov. (Hemiptera, Liviidae, Euphyllurinae) and adults of Tamarixia dorchinae sp. nov. (Hymenoptera, Eulophidae, Tetrastichinae) from Israel are described, diagnosed and illustrated. D. teucrii sp. nov. develops on Teucrium capitatum (Lamiaceae), representing a family which was previously not recorded as a psyllid host from Israel, and is parasitised...

The Indian species of Closterocerus Westwood, 1833 (Hymenoptera: Chalcidoidea: Eulophidae: Entedoninae) are reviewed; eight included which two described as new: C. pakyongensis sp. nov. and junubi One species: longiscapus (Bouček, 1986), is recorded from Uttar Pradesh for the first time. An identification key to occurring in India also given.

The aim of this note is to report the parasitism Aleurodicus pseudugesii Martin, 2008 (Hemiptera: Aleyrodidae) nymphs by Aleuroctonus marki Hansson & LaSalle, 2003 (Hymenoptera: Eulophidae) in coconut palm Cocos nucifera L. (Arecaceae) Santa Izabel do Pará, a municipality Eastern Amazon. This first recorded instance parasitoid species A. pseudugesii.

Inti gen. nov. (Hymenoptera: Eulophidae: Entedoninae), is described from Costa Rica and the Dominican Republic, and includes one new species, I. levis sp. nov. The new genus is characterized by four autapomorphies, and the possession of an additional 14 synapomorphies. Inti is compared to the Australian genus Horismenoides Girault with which it shares the most apomorphies, indicating a possible...

Horismenus parasitoids are an abundant and understudied group of eulophid wasps found mainly in the New World. Recent surveys based on morphological analyses in Costa Rica have quadrupled the number of named taxa, with more than 400 species described so far. This recent revision suggests that there is still a vast number of unknown species to be identified. As Horismenus wasps have been widely ...
