Morphology and Chemical Characterization of the Metathoracic Scent Gland in Halyomorpha halys (Stål, 1855) (Hemiptera: Heteroptera: Pentatomidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Halyomorpha halys (Stål, 1855) is an invasive pentatomid species causing considerable economic losses in agricultural systems. Despite the ecological importance of the metathoracic scent gland (MTG) in chemical defence and communication, detailed information on its morphology and secretion composition remains limited. In the present study, the

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia 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.

Canopy position and tree size structure the distribution of honeydew‐producing scale insects (Hemiptera: Coccoidea) in a temperate hardwood forest

open access: yesEcological Entomology, EarlyView.
Scale insect abundance peaked in the upper canopy of sugar maples. Parthenolecanium peaked on older internodes; Lepidosaphes on the current leader. Internodes longer than the previous carried more scales; wider ones fewer. Abstract Forest canopies are vertically stratified habitats in which microclimate and host tissue quality vary with height.

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

Hydromulches in Organic Strawberry Production: Effects on Densities of Insect Pests and Natural Enemies

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Liquid‐sprayable cellulose hydromulches (HM) are alternatives to plastic polyethylene (PE) mulches for weed suppression in organic agriculture. However, their impact on arthropod pests and natural enemies remains unexplored. Various HMs made of shredded newsprint, water and guar gum were compared against white‐on‐black PE mulch, paper sheet ...

Insecticidal activities of the African yam bean seed lectin on the development of the cowpea beetle and the pod sucking bug

open access: yes, 2019
The cowpea beetle, Callosobruchus maculatus, and pod-sucking bug, Clavigralla tomentosicollis, are two of the major insect pests of cowpea in Africa. A lectin was purified from the seeds of the African yam bean (AYB), Sphenostylis stenocarpa, by affinity

Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Pesticide Supply Chains From China to Australia: Examining Paraquat Amid the Global Pesticide Complex

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Following recent calls to deepen understanding of the Global Pesticide Complex, this article delves into the China‐to‐Australia supply chain of a single herbicide—paraquat. First released in the United Kingdom in the 1960s, acutely toxic paraquat is now primarily produced in China.

Evaluation of Selected Pigeonpea (Cajanus cajan (L.) Millsp.) Genotypes for Resistance to Insect Pest Complex in Dry Areas of North Rift Valley, Kenya [PDF]

open access: yes, 2016
Pigeonpea is an important pulse crop that has gained importance in semi-arid tropics, although its yield potential has not been fully realized due to biotic and abiotic stresses that limit its production.
