Chromosomes of Aphidius ervi Haliday, 1834 (Hymenoptera: Braconidae).
Die Chromosomenanalyse einiger Laborlinien von Aphidius ervi Haliday, 1834 aus Deutschland ergab n=5 und 2n=10. Allerdings wurden bei einigen weiblichen Tieren einer Population Chromosomensätze mit 2n=12 gefunden. Diese Tiere repräsentieren wahrscheinlich eine thelythoke Linie, die aus einer ursprünglich arrhenotoken Population hervorging. Der Karyotyp

We used automated activity monitors to examine how light‐emitting diode illumination affects the daily locomotor activity of the parasitoid biocontrol agent Aphidius matricariae. We compared 4‐ to 20 h broad‐spectrum white (BSW) photoperiods, and 12 h BSW photoperiods extended with an additional 6 h of red‐blue, red‐green‐blue, or BSW light, or no ...

An experimental test of whether the defensive phenotype of an aphid facultative symbiont can respond to selection within a host lineage. [PDF]
An experiment was conducted to test whether parasitoid resistance within a single clonal line of pea aphid (Acyrthosiphon pisum) might increase after exposure to the parasitoid wasp Aphidius ervi. Any change in resistance was expected to occur through an

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids
Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.

NATURAL ENEMIES OF DIURAPHIS NOXIA (STERNORRHYNCHA: APHIDIDAE) IN SLOVAKIA [PDF]
A study from 2002 documented the occurrence of natural enemies (parasitoid wasps, predatory fl ies, entomopathogenic fungi) associated with colonies of the Russian wheat aphid, Diuraphis noxia (Kurdjumov, 1913) (Sternorrhyncha: Aphididae), in the spring ...

Survival to parasitoids in an insect hosting defensive symbionts: a multivariate approach to polymorphic traits affecting host use by its natural enemy. [PDF]
Insect parasitoids and their insect hosts represent a wide range of parasitic trophic relations that can be used to understand the evolution of biotic diversity on earth.

Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

Les pucerons des cultures protégées et leurs ennemis en Tunisie [PDF]
Aphids in the protected crops and their natural enemy in Tunisia. The importance of damage caused by aphids in protected crops, led us to carry out the inventory of aphids as well as the antagonists and to study the distribution of aphid population of ...
