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.

Insect Science, EarlyView.We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Annotated checklist and illustrated key to braconid parasitoids (Hymenoptera, Braconidae) of economically important fruit flies (Diptera, Tephritidae) in Brazil [PDF]
, 2018 The braconid parasitoids of fruit-infesting flies have been more intensively studied from the middle to late 1990s, when taxonomic research was restarted in Brazil.

Egg Parasitoids of Homalodisca coagulata (Homoptera: Cicadellidae)
The Florida Entomologist, 1998 The glassy-winged sharpshooter, Homalodisca coagulata (Say), is native to the southeastern United States. It has existed in southern California since about 1990 (Sorensen & Gill 1996), and has become an economic problem as a vector of the pathogenic bacterium Xylella sp., that is the cause of leaf scorch disease in oleander.

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.

InsectsTrichogramma is an important genus of egg parasitoids, applied against agricultural and forest lepidopteran pests. Known species differ in host specificity, which affects both their efficiency in field and suitability for mass rearing.

Epizootiology of the Fungal Pathogen, \u3ci\u3eZoophthora Phytonomi\u3c/i\u3e (Zygomycetes: Entomophthorales) in Field Populations of Alfalfa Weevil (Coleoptera: Curculionidae) Larvae in Illinois [PDF]
, 2017 The influence of the fungal pathogen, Zoophthora phytonomi, on larvae of the alfalfa weevil, Hypera postica, was studied in three alfalfa fields in Illinois. Disease epizootics occurred in all three fields and disease onset was ob- served within a fairly

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.

Reversed impacts by specialist parasitoids and generalist predators may explain a phase lag in moth cycles : a novel hypothesis and preliminary field tests [PDF]
, 2013 Among cyclic populations of herbivores, inter-specific temporal synchrony has been attributed to both climatic factors and trophic interactions. In northern Europe, winter and autumnal moths undergo regular 9–11 year population cycles.

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.
