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

open access: yesInsect 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.

“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

open access: yesInsect 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.

First incursion of the Asian root mealybug Ripersiella planetica in Europe (Hemiptera, Coccoidea, Rhizoecidae) [PDF]

open access: yes, 2012
The Rhizoecidae is a family of the Coccoidea (hodGSon, 2012) containing 233 species worldwide that are hypogaeic and parasitic on plant roots, hence their common name ‘root mealybugs’ (Kozár & Konczné BEnEdicty, 2007).

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.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

The ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae) as a possible predator of grape phylloxera Daktulosphaira vitifoliae (Hemiptera: Phylloxeridae)

open access: yesEuropean Journal of Entomology, 2013
The ladybird beetle Harmonia axyridis (Pallas 1773) has been used for biological control in several countries. However, it became invasive in some of those countries. Coccinella septempunctata (Linné 1758) is a native species in Europe.
