Farmscaping

Jarrod Fowler

Introduction

Crop-specific farmscaping can prevent crop-specific pests. Plan predator-specific habitats that host pest-specific predators who prey on crop-specific pests. Select from 70 common row crops belonging to 11 plant families. Learn the common economically injurious pests of selected crops, the known natural enemies of those pests of those crops, and the farmscaping practices that host those enemies of those pests of those crops. Divest from pesticides!

Results

Sixty-seven species of pests and over 200 species of parasitoids, predators, and pathogens were listed. Please consider prevention of the following eight most recurrent pest species as basic for balanced farmscapes:

  1. True armyworm - Mythimna unipuncta (Haworth, 1809) [Lepidoptera: Noctuidae] = 10/11 crop families
  2. Wireworm - Melanotus spp. Eschscholtz 1829 and Limonius spp. Eschscholtz, 1829 [Coleoptera: Elateridae] = 9/11 crop families
  3. Saltmarsh caterpillar - Estigmene acrea (Drury, 1773) [Lepidoptera: Erebidae] = 9/11 crop families
  4. Corn earworm / Tomato fruitworm - Helicoverpa zea (Boddie, 1850) [Lepidoptera: Noctuidae] = 9/11 crop families
  5. Tarnished plant bug - Lygus lineolaris (Palisot de Beauvois, 1818) [Hemiptera: Miridae] = 9/11 crop families
  6. Aster leafhopper - Macrosteles quadrilineatus (Forbes 1885) [Hemiptera: Cicadellidae] = 6/11 crop families
  7. Harlequin bug - Murgantia histrionica (Hahn 1834) [Hemiptera: Pentatomidae] = 5/11 crop families
  8. Variegated cutworm - Peridroma saucia (Hübner, [1808]) [Lepidoptera: Noctuidae] = 5/11 crop families

Natural enemies were most often parasitoid wasps, predatory beetles, and predatory bugs. Parasitoid flies, entomopathogens, lacewings, lady beetles, ground beetles, and spiders were found to regularly contribute crucial pest regulation services. Conservation of the most recurrent natural enemies should be of primary concern when planning balanced farmscapes. Farmscape practices that support the most recurrent natural enemies included the creation, augmentation, or conservation of temporary insecaries, semi-permanent cover crops, and permanent plantings such as windbreaks, hedgerows, grasslands, meadows, prairies, pastures, and beetle banks. Farmscape features feed natural enemies nectar, pollen, and alternate prey, while providing nests or overwintering shelters, and protecting natural enemies from habitat disturbances. Increased crop diversity, reduced tillage, and enhanced organic soil amendments and mulches can reduce pest outbreaks and preserve populations of predators and pathogens.
