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

Insect 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.

Identification of limonene as a potential kairomone of the harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae)

European Journal of Entomology, 2010
Chemical cues involved in both host location and oviposition by Harmonia axyridis Pallas (Coleoptera: Coccinellidae) were investigated in laboratory and field experiments.

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Ladybird Coccinella septempunctata (Coleoptera: Coccinellidae) prefers toxic prey in laboratory choice experiment

European Journal of Entomology, 2008
In a laboratory experiment, we investigated the preference of larvae and adults of Coccinella septempunctata (Coleoptera: Coccinellidae) for three aphid species: two essential prey, Acyrthosiphon pisum and Aphis philadelphi, and a toxic prey Aphis ...

“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

Insect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.

Response of Coccinella septempunctata and Menochilus sexmaculatus (Coleoptera: Coccinellidae) to their aphid prey, Lipaphis erysimi (Hemiptera: Aphididae) in rapeseed-mustard

European Journal of Entomology, 2006
During a three year study in rapeseed-mustard crop, the response of two ladybird species, Coccinella septempunctata and Menochilus sexmaculatus was dependent upon density and time of appearance of their prey.

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

Insect 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.

Phenotypic plasticity of elytron length in wingless two-spot ladybird beetles, Adalia bipunctata (Coleoptera: Coccinellidae)

European Journal of Entomology, 2005
Winglessness in the two-spot ladybird beetle Adalia bipunctata (L.) is determined by a single locus with the wingless allele recessive to the winged wildtype allele.
