In this study, it was tried to determine the amount of prey consumed by Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) at varying densities and its potency in reducing population pest. Aphids used as nutrients [Aphis fabae Scopoli Acyrthosiphon pisum Harris (Hemiptera: Aphididae)] were given each larval stage (InstarI, InstarII, InstarIII) predator certain numbers (5, 10, 20, 40, 80, 1...

همراه با جمع‌آوری زنبورهای پارازیتویید شته‌ها در ایران طی سال‌های 1385-1380، تعداد چهار گونه زنبور هیپرپارازیتویید نیز جمع‌آوری و شناسایی شد که دو گونه‌ی Alloxysta fulviceps (Curtis) و A. victrix (Westwood) برای فون ایران جدید می‌باشند. گونه‌ی A. fulviceps هیپرپارازیتویید زنبور Aphidius matricariae Haliday روی شته‌ی Aphis fabae Scopoli و گونه‌ی A. victrix هیپرپارازیتویید زنبور Lysiphlebus fabar...

In response to a predator attack, many Aphidinae species release an alarm pheromone, which induces dispersal behavior in other individuals within the colony. The major component of this pheromone is the sesquiterpene (E)-β-farnesene (Eβf), but variations occur between aphid species. In the present work, we collected, identified, and quantified the alarm pheromone of Aphis craccivora Koch (Hemip...

به منظور جمع‌آوری و شناسایی پارازیتوئیدهای شته‌ی سیاه باقلا، Scopoli Aphis fabae، از مزارع باقلای منطقه‌ی چورزق زنجان در اواسط خرداد‌ماه 1386 نمونه‌برداری به عمل آمد. در بین نمونه‌ها، جمعیت ماده‌‌زای زنبور پارازیتوئید Lysiphlebus fabarum (Marshall) از خانواده‌ی Aphidiidae شناسایی شد که برای اولین‌بار از ایران گزارش می‌‌شود. در زیر برخی ازویژگی‌‌های مهم تولید مثلی و چگونگی پراکنش جغرافیایی این ج...

In Iran, Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae: Aphidiinae) is a uniparental parasitoid of the black bean aphid, Aphis fabae Scopoli (Hemiptera: Aphididae), that possesses various highly evolved adaptations for foraging within ant-tended aphid colonies. Direct observations and video recordings were used to analyze the behavior of individual females foraging for A. fabae on bea...

Generalist predator guilds play a prominent role in structuring insect communities and can contribute to limiting population sizes of insect pest species. A consequence of dietary breadth, particularly in predatory insects, is the inclusion of low-quality, or even toxic, prey items in the predator's diet. Consumption of low-quality prey items reduces growth, development, and survival of predato...

Many animal paths have an intricate statistical pattern that manifests itself as a power law-like tail in the distribution of movement lengths. Such distributions occur if individuals move according to a Lévy flight (a mode of dispersal in which the distance moved follows a power law), or if there is variation between individuals such that some individuals move much farther than others. Disting...

Aphids and ants are relatively well faunistically studied in Serbia. However, there is a need to present the mutualistic associations between these two groups of insects, since not sufficient information on this topic for territory under investigation. In total, 220 samples plant-aphid-ant were included study. 59 localities from all parts Serbia, 32 ant taxa registered connected with 74 identif...

Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases currently impossible to treat but knowing the flight patterns of can help reducing number potential virus vectors. Monitoring aphid activities fields was done using yellow water traps from April end November. During two years investigation, a total 5514 specimens 75 different taxa wer...
