High rates of parasitism of blueberry spanworm (Lepidoptera: Geometridae) by Ichneumonidae and Tachinidae in commercial lowbush blueberry fields

The plants surrounding rice field serve as a habitat and niche for entomophagous arthropods. This study aimed to identify the entomophagous arthropod species and to analyze their abundance and community in vegetables and refugia grown in the rice field. The field was surrounded by 4 species of refugia (Zinnia sp., Tagetes erecta, Cosmos caudatus, and Sesamum indicum) and 4 species of vegetables (Vigna unguiculata, Momordica charantia, Cucumis sativus, and Luffa acutangula). The arthropod found were 67 species of predatory arthropods and 22 species of parasitoids. The predatory arthropods were mostly found in rice (51 species) followed by Zinnia sp. (15 species), and M. charantia (9 species). Parasitoid species were dominantly found in rice (19 species), Zinnia sp. (7 species), and M. charantia (6 species). The predatory arthropods mostly found were Tetragnatha javana, Tetragnatha virescens, and Paederus fuscipes, while the dominant parasitoids were Cardiochiles sp., Elasmus sp., and Snellenius sp. The parasitoid species composition in rice was more similar to those in bitter melon and zinnia. The composition of predatory arthropod species in rice was similar to those in all vegetables and refugia, except in cowpea. Zinnia sp. and M. charantia were the most chosen habitat by entomophagous arthropods.

“…As lowbush blueberry is grown in its native range, native natural enemies and bees that have coevolved with the crop can be found in this agroecosystem. Natural enemies, including ground beetles (Coleoptera: Carabidae) and parasitic wasps (Hymenoptera: Ichneumonidae), consume insect pests in lowbush blueberry, such as blueberry spanworm (Itame argillacearia Packard), blueberry maggot (Rhagoletis mendax Curran) and red sorrel (Rumex acetosella L.) weed seeds (Renkema et al 2013(Renkema et al , 2014Cutler et al 2015a;Loureiro and Cutler 2016;Loureiro et al 2020). In addition to biological control, pollination from wild bees contributes greatly to lowbush blueberry production.…”

The impact of planting buckwheat strips along lowbush blueberry fields on beneficial insects

Pollination and pest control are important in many agroecosystems. Beneficial insects that provide these services (e.g. bees and natural enemies) often require floral resources beyond crop bloom. Planting floral resources along crop field margins may be a useful tactic to support communities of beneficial insects in agroecosystems. We examined the effect of planting buckwheat (Fagopyrum esculentum Moench) along lowbush blueberry (Vaccinium angustifolium Aiton) field margins on beneficial insect abundance and species richness. We found that bee abundance was higher in buckwheat transects than control transects in 2014 and 2015, but not 2016, and that bee species richness was higher in buckwheat transects than in control transects in 2015 only. High variability occurred across years. All bee genera recorded during blueberry bloom were also collected in buckwheat transects, suggesting buckwheat is a useful resource for bee community involved in blueberry pollination. The effect of buckwheat on natural enemies was variable and inconsistent. We conclude buckwheat influenced bee and natural enemy communities during certain years, but field edges in the lowbush blueberry fields studied may already adequately support beneficial insects. Thus, not all habitat management efforts with augmentative floral plantings may consistently boost communities of beneficial insects.
