In the study of parasitoids of the plane leaf miner Phyllonorycter platani during 2004, 18 polyphagous parasitoid species were recorded in four tree rows and four parks in Serbia (3 species of the family Ichneumonidae and 15 species of the family Eulophidae). Among the recorded parasitoids, the most significant were the species Minotetrastichus platanellus, Pediobius saulius and M. frontalis, f...

Prepupae of Hypera eximia (LeConte) (Coleoptera: Curculionidae), a natural host, and prepupae of factitious insect hosts were tested for their physiological responses to stinging by the gregarious ectoparasite, Necremnus breviramulus Gahan (Hymenoptera: Eulophidae), and to injection with an extract of the venom gland tissue dissected from the lower reproductive tract of the female parasite. The...

Diaphorina citri Kuwayama (Hemiptera: Psyllidae), vectors the bacterium Candidatus Liberibacter asiaticus, one of the causal organisms of the devastating citrus disease "huanglongbing" or citrus greening. In the United States, D. citri was first discovered in Florida, in 1998. Tamarixia radiata Waterston (Hymenoptera: Eulophidae) was imported from Asia and released in Florida in 1999-2001 to im...

The mass rearing of parasitoids represents a fundamental stage for programmes of biological control. The progeny of the parasitoid Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae) were evaluated on previously refrigerated pupae of Bombyx mori L. (Lepidoptera: Bombycidae). Forty-eight to 72 hours-old pupae of B. mori were stored at 10 °C for five, 10, 15 or 20 days and then ex...

Karyotypes of eleven parasitoid species of the family Eulophidae were examined, namely, Chrysocharis laomedon (Walker, 1839) (2n = 10), Chrysocharis sp. aff. laomedon (n = 5, 2n = 10), Chrysocharis sp. aff. albipes (Ashmead, 1904) (2n = 12), Mischotetrastichus petiolatus (Erdös, 1961) (n = 6, 2n = 12), Minotetrastichus frontalis (Nees, 1834) (n = 5, 2n = 10), Cirrospilus pictus (Nees, 1834) (2n...

We report the occurrence of natural enemies of Plutella xylostela (L.) in organically farmed kale in Pernambuco, Brazil. Seven natural enemies were observed parasitizing or preying on larvae and pupae of P. xylostella--three parasitoids: Cotesia plutellae Kurdjumov (Hym.: Braconidae), Conura pseudofulvovariegata (Becker) (Hym.: Chalcididae) and Tetrastichus howardi (Olliff) (Hym.: Eulophidae), ...

Two closely related new species of Aprostocetus Westwood (Hymenoptera: Eulophidae: Tetrastichinae) are described as fortuitous parasitoids of invasive gall inducers in two other genera of Tetrastichinae, Leptocybe Fisher & LaSalle and Quadrastichus Girault. Aprostocetus causalis La Salle & Wu is a parasitoid of Leptocybe invasa Fisher & La Salle on Eucalyptus spp. (Myrtaceae) in China and Thail...

اواسط شهریور 1401 و در نزدیکی ساحل ماسه‌ای رودخانۀ نکا شمال ایران، به روش تورزدن روی گل‌آذین بوته‌های کاهوک (.Lactuca serriola L) میان تمشک وحشی (.Rubus idaeus انار (.Punica granatum L)، نمونه‌ای جیرجیرک جمع‌آوری شد که بررسی توسط کلیدهای شناسایی شکل‌شناسی مقایسه با نمونه‌های از قبل تعیین نام شدۀ موزۀ حشرات هایک میرزایانس رکورد جدید جنس گونه را تایید کرد. این اولین گزارش گونۀ Arachnocephalus ves...
