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

Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Endosymbiosis morphological reorganization during metamorphosis diverges in weevils
Virtually all animals associate with beneficial symbiotic bacteria. Whether and how these associations are modulated across a host’s lifecycle is an important question in disentangling animal-bacteria interactions. We recently reported a case of complete

MODELING FARM AND OFF-FARM ECONOMIC LINKAGES TO ANALYZE THE IMPACTS OF AN AREA-WIDE INSECT MANAGEMENT PROGRAM ON A REGIONAL ECONOMY [PDF]
This study evaluated the impacts of the boll weevil eradication program at the farm level and on the west Tennessee region. Budgets, an acreage response model, and an input-output model were used to evaluate direct and indirect program impacts.

The bread of Toledo: Prices and political economy, 1535–1800
Abstract We study the market for common white bread in the city of Toledo through a new 266‐year‐long series of bread prices, obtained from the cash purchases and wholesale bread‐for‐wheat contracts of large institutions. Our data are strongly consistent with fragmentary evidence on retail price regulation, as well as with shorter series from other ...

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.

Robel Pole Method Can Estimate Cereal Rye Biomass to Optimize Termination Timing
Abstract Fully realizing the benefits of cover crops and minimizing the yield penalty requires knowing when to terminate them. Cereal rye (Secale cereale L.) is the dominant cover crop used in the Midwest US, and previous work has shown that corn (Zea mays L.) yield penalties began to occur more frequently when cereal rye is at ∼1000 lb dry biomass ac ...

The role and use of Epichloë fungal endophytes in grazed temperate grass pastures and turf grasses are now well understood with regard to balancing pasture persistence while minimising animal health and welfare concerns. However, this understanding has only emerged since the early 1980s. Prior to this, although links between Epichloë endophytes, animal
