The cotton aphid, Aphis gossypii Glover and predators on Catalpa bignonioides Walt.

open access: yesActa Agriculturae Slovenica, 2002
In 1998–2001, the cotton aphid (Aphis gossypii Glover, Homoptera, Aphididae) was found to complete its holocycle on Catalpa bignonioides Walt. in Ljubljana (Slovenia). The infested leaves showed curling. The aphid was very damaging by causing the flowers

Leucopis annulipes larvae (Diptera: Chamaemyiidae) use a furtive predation strategy within aphid colonies

open access: yesEuropean Journal of Entomology, 2008
A laboratory experiment was conducted to determine whether the predation strategy of larvae of the aphidophagous silver fly Leucopis annulipes Zetterstedt (Diptera: Chamaemyiidae) is furtive, as are larvae of the aphidophagous midge Aphidoletes ...

Disjunction between canola distribution and the genetic structure of its recently described pest, the canola flower midge (Contarinia brassicola)

open access: yesEcology and Evolution, Volume 10, Issue 23, Page 13284-13296, December 2020., 2020
The canola flower midge is a newly discovered pest of canola from the Canadian Prairies. The population genetic analyses presented in this study recovered little population structure across its known range, consistent with high levels of gene flow in this region.

Diapausing larvae of the midge Aphidoletes aphidimyza (Diptera: Cecidomyiidae) survive at subzero temperatures in a supercooled state but tolerate freezing if inoculated by external ice

open access: yesEuropean Journal of Entomology, 2000
Diapausing larvae of Aphidoletes aphidimyza (Diptera: Cecidomyiidae) had relatively low supercooling points (SCP) ranging from -19.0 to -26.4°C. None of the specimens that froze at this temperature survived.

Insects in production – an introduction

open access: yesEntomologia Experimentalis et Applicata, Volume 168, Issue 6-7, Page 422-431, July 2020., 2020
Insects have been on the menu of humans for centuries, but only recently their mass production for human food and animal feed started. First, we inventory mass cultured insects and their application. The insect production industry raises many interesting questions about insect biology and fitness.

Les pucerons des cultures protégées et leurs ennemis en Tunisie [PDF]

open access: yesTropicultura, 1993
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 ...

The effect of interaguild predation on avoidance behavior of the aphidophagous midge, Aphidoletes aphidimyza (Dip.: Cecidomyiidae) on its encounter with the predatory bug Orius laevigatus (Het.: Anthocoridae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2013
The predatory bug, Orius laevigatus (Fibber), and the predatory midge, Aphidoletes aphidimyza Rondani, belong to an aphidophagous guild, feeding on the cotton aphid Aphis gossypii Glover.

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

open access: yesInsect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.
