On the misidentification of Anagrus ustulatus Haliday (Hymenoptera: Mymaridae).
The cosmopolitan genus Anagrus Haliday is one of the largest in Mymaridae (Hymenoptera: Chalcidoidea), and includes very common egg parasitoids, mostly of leafhoppers. The smallest species (body length: 0.4-0.6 mm) are found in the atomus species group. This group at present includes about 20 species worldwide. Anagrus atomus (Linnaeus) is among the most common species in the Palaearctic region...
متن کاملFirst known host records for the egg parasitoid Gonatocerus californicus (Hymenoptera Mymaridae)
Two leafhopper (Hemiptera Cicadellidae) hosts are reported for Gonatocerus (Gonatocerus) californicus Girault (Hymenoptera Mymaridae): Exitianus obscurinervis (Stal) and Spangbergiella vulnerata lacerdae Signoret. At El Manantial site in Tucumán Province, Argentina, G. californicus emerged from 7.1% and 90.5% of the parasitized sentinel eggs of the respective host on maize plants. Notes on the ...
متن کاملAbsence of Transgenerational Phenotypic Plasticity in Fecundity in the Parasitoid Anagrus erythroneurae (Hymenoptera: Mymaridae)
To improve biological pest control, we would like to understand the main factors that limit the reproductive success of key biological control agents, including parasitoid wasps. Previous research with proovigenic parasitoids in the genus Anagrus collected from multiple field sites revealed positive correlations between parasitoid fecundity and local host density. In this article, we test wheth...
متن کاملA new species of Anagrus (Hymenoptera: Mymaridae) from Amazonas, Brazil.
A new fairyfly species from the Neotropics, Anagrus (Anagrus) amazonensis Triapitsyn, Querino & Feitosa, sp. n., is described and illustrated. Anagrus Haliday is a large genus of Mymaridae (Hymenoptera), which now includes eight species recorded from Brazil. This new species attacks eggs of damselflies (Odonata: Zygoptera).
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
