Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge
Insect Science, EarlyView.Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Insect Science, EarlyView.This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Combined effects of the landscape and crop management on ant communities
Agricultural and Forest Entomology, EarlyView.At small spatial scales, agricultural management acts as a stronger ecological filter than landscape context, significantly shaping ant community composition. Species richness and frequency did not differ among treatments, indicating the predominance of generalist species.

SP290-S-Mealybugs on Ornamentals [PDF]
, 2003 Mealybugs are worldwide pests of ornamental plants grown indoors and outdoors. Both greenhouse and field-grown ornamentals are commonly attacked. Damage to ornamentals occurs when mealybugs insert their needlelike mouthparts into host plants and suck out

, 2006 Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae).

Entomologia Experimentalis et Applicata, EarlyView.MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

A delay differential equation model of mealybugs and green lacewings
Advances in Difference Equations, 2019 In this paper, we propose and analyze a mathematical model of mealybugs and green lacewings with time delay to investigate the population dynamics of mealybugs (a major insect pest of cassava) and green lacewings (a natural enemy of mealybugs) when the ...

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems
Entomologia Experimentalis et Applicata, EarlyView.We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.
