Insect Science, EarlyView.Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Parasitoid load affects plant fitness in a tritrophic system [PDF]
, 2008 Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont ...

Iflaviruses in arthropods: when small is mighty
Insect Science, EarlyView.Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

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.

A NEW MEALYBUG PARASITE (HYMENOPTERA: SCELIONIDAE) [PDF]
The Canadian Entomologist, 1939 The purpose of this paper is to provide a name for an undescribed species of the platygasterine genus Allotropa which has been encountered in Canada as a parasite of the mealybug Phenacoccus aceris (Sign.). Brief notes are also given on the single previously known Nearctic species of Allotropa and on another species which was erroneously described in ...

Reduced fertilization regimes could boost biocontrol service without reducing crop yield
Insect 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.

Syrphophilus bizonarius (Gravenhorst, 1829) (Hymenoptera) - new to Malta, with a revised check-list of the Ichneumonidae of the Maltese Islands [PDF]
, 2012 The Ichneumonidae is a species rich family with 36,179 valid species recorded by yu & horStmAnn (1997). Ichneumonids utilise a diverse array of insects and arachnids as their hosts and play an essential role in the normal functioning of terrestrial ...
