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 ...

First Detailed Record of Jikradia olitoria (Hemiptera: Cicadellidae) in the Swiss Southern Alps and Evaluation of Its Current Potential as a Vector of 16SrV‐Phytoplasmas

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

Effects of Early Season Temperature on Adult Life History Traits of Wheat Stem Sawfly, Cephus cinctus (Hymenoptera: Cephidae) and Bracon cephi (Hymenoptera: Braconidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a long‐standing and serious pest of wheat, Triticum aestivum Linnaeus (Poaceae), in the northern Great Plains region of North America. Over the last decade, research efforts have aimed to better understand C.

First Record of Larval Parasitism in Disonycha glabrata (F.) (Coleoptera: Chrysomelidae) by Myiopharus ancilla (Walker) (Diptera: Tachinidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The amaranth flea beetle, Disonycha glabrata (F.), is a major pest of amaranth crops (Amaranthus spp.) in the United States. Despite its economic impact, its natural enemy complex remains poorly documented. In this study, we report the first record of larval parasitism in D. glabrata by the tachinid fly Myiopharus ancilla (Walker).

Bait Response and Fruit‐Associated Abundance Patterns of Two Introduced Zaprionus Species in Tropical Orchards

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Fruit‐associated drosophilids are expanding in fruit‐growing landscapes, but field information on bait response and fruit‐associated occurrence remains limited for recently introduced species. We evaluated Zaprionus indianus Gupta and Zaprionus tuberculatus Malloch (Diptera: Drosophilidae) in homestead orchards of the Agreste region of Paraíba,

Agroecosystem health, agroecosystem resilience, and food security

Journal of Environmental Studies and Sciences, 2015
This paper lays out the relationships between three mutually reinforcing concepts associated with agroecosystems: (1) agroecosystem health, the extent to which an agroecosystem can meet human needs for all of its residents over time; (2) resilience, the capacity of a system to adapt, reorganize, and maintain key functions in the face of turbulent and ...

Managing Sulphur in Agroecosystems

2003
This chapter discusses the global biogeochemical sulphur (S) cycle and S pool, the role of nutrient management, in general, and of S management, in particular, in achieving agronomic and environmental objectives. Understanding the biogeochemical cycling of S is of crucial importance for S management in agroecosystems.
