Urban greenery aphids (Hemiptera, Aphididae) [PDF]

Archives of Biological Sciences, 2013
In 2010-2011, a study of the occurrence of aphids was carried out in three parks in Bydgoszcz, the Balaton Park, the Jan Kochanowski Park and the Park by Unii Lubelskiej. Observations were made every ten days by monitoring trees and shrubs as soon as aphids appeared, i.e. from the end of April to the beginning of August.

Minimising insect mortality during grassland mowing: The potential of insect chasing devices

Insect Conservation and Diversity, EarlyView.
Insect chasing devices have a great potential to deter arthropods prior to mowing, thereby reducing mortality. The effectiveness of mechanical flushing bars is limited and depends on driving speed, vegetation structure and species composition. The blowing device is the most independent of external factors and therefore the most effective.

Influence of different species of aphid prey on the immature survival and development of four species of aphidophagous coccinellids (Coleoptera: Coccinellidae)

European Journal of Entomology, 2015
This study was on the effect of three species of aphids (Aphis fabae, Macrosiphoniella sanborni, Brevicoryne brassicae) on the survival, growth and development of the immature stages of the aphidophagous coccinellids Coccinella septempunctata ...

Studies on Aphididæ. I.* [PDF]

Annals of the Entomological Society of America, 1908
What is supposed to be this species was first described by Asa Fitch in his “Catalogueof the Homoptera of New York” in 1851 as Aphis betulA¦colens . Monell described it from Missouri as Callipterus betulA¦colens , n. sp., and placed Aphis betulA¦colens of Fitch as doubtfully synonymous. Thomas hesitatingly placed this species and Calaphis betulella

Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

Insect Conservation and Diversity, EarlyView.
We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

Respiratory metabolism of the pea aphid, Acyrthosiphon pisum (Hemiptera: Aphididae)

European Journal of Entomology, 2012
The respiratory metabolism of different polyphenic forms of the pea aphid, including wingless and winged asexual females (virginoparae), sexual females (oviparae) and winged or wingless adult males, was investigated using a micro-respirographic method ...

Spatial Interpolation in Applied Insect Ecology: A Review, Including Guidelines and Datasets for Practical Use

Journal of Applied Entomology, EarlyView.
ABSTRACT Spatial interpolation represents a fundamental approach in applied insect ecology, offering insight into species distributions and supporting biodiversity analysis, pest management and disease vector mapping. Insects—including important pollinators—face escalating threats due to habitat loss, climate change and anthropogenic pressures. As data‐

The effect of choice and no-choice access on host (Aphis fabae) instars preference, in different ages and sizes of Lysiphlebus fabarum (Hymenoptera: Braconidae: Aphidiinae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2016
The influence of parasitoids on population dynamics is affected by host instar preference. The preference pattern of host instars is not fixed and is modified by the availability and relative abundance of host instars, intensity of defensive behaviors in
