Viticultural practices and landscape composition are the main drivers influencing biological pest control in vineyards. Predatory mites, mainly phytoseiid (Phytoseiidae) and tydeoid mites (Tydeidae), are important to control phytophagous mites (Tetranychidae and Eriophyidae) on vines. In the absence of arthropod prey, pollen is an important food source for predatory mites. In 32 paired vineyards located in Burgenland/Austria, we examined the effect of landscape composition, management type (organic/integrated), pesticide use, and cover crop diversity of the inter-row on the densities of phytoseiid, tydeoid, and phytophagous mites. In addition, we sampled pollen on vine leaves. Typhlodromus pyri Scheuten was the main phytoseiid mite species and Tydeus goetzi Schruft the main tydeoid species. Interestingly, the area-related acute pesticide toxicity loading was higher in organic than in integrated vineyards. The densities of phytoseiid and tydeoid mites was higher in integrated vineyards and in vineyards with spontaneous vegetation. Their population also profited from an increased viticultural area at the landscape scale. Eriophyoid mite densities were extremely low across all vineyards and spider mites were absent. Biological pest control of phytophagous mites benefits from less intensive pesticide use and spontaneous vegetation cover in vineyard inter-rows, which should be considered in agri-environmental schemes.

This study was carried out to determine mite species on blackberry plants (Rubus spp. (Rosaceae)) in Florida and Georgia, USA, and differences in mite species between organic and conventional blackberry plantings in the area sampled. Surveys were conducted in organic and conventional commercial blackberry plantings from June to October 2016. Leaf samples were collected monthly from nine different blackberry cultivars including ‘Arapaho’, ‘Choctaw’, ‘Freedom’, ‘Kiowa’, ‘Natchez’, ‘Navaho’, ‘Osage’, ‘Ouachita’, and Von. Approximately 20 leaves per blackberry plant were taken. Twenty mite species (a total of 152 mite specimens) belonging to 7 families including Phytoseiidae (9 species), Ascidae (1), Cheyletidae (1), Erythraeidae (1), Stigmaeidae (1), Tetranychidae (4) and Tarsonemidae (3) were identified during the study. It was found that the abundance of predatory mites collected in organic farms was over 2-fold higher (105) than in conventional farms (47), which may be related to pesticide use on these commercial farms. Future surveys should provide a list of predatory species, which may hold potential for biological control of economically important pest mites.

Coordination Strategies

Transitioning towards agroecology involves the integration of biodiversity based ecosystem services into farming systems: for example, relying on biological pest control rather than pesticides. One promising approach for pest control relies on the conservation of semi-natural habitats at the landscape scale to encourage natural enemies of insect pests. However, this approach may require coordination between farmers to manage the interdependencies between the providers and beneficiaries of this ecosystem service. The main objective of this study was to identify hindrances to landscape-scale coordination strategies to control pests. To this end, we used a theoretical framework specifically designed to explore social interdependencies linked to ecosystem services. We applied this framework to a participatory research case study on pest control in apple orchards in southwest France to identify and describe key obstacles. We found four main impediments: (1) The perception of most stakeholders that the landscape does not deliver significant pest control services, (2) the challenge of coping with agroecological uncertainties, (3) an integrated vertical supply chain focused on pesticide use, (4) the existence of independent, non-collective alternatives. We discuss the potential of overcoming these obstacles or turning them into opportunities that promote a transition to agroecology and the integration of ecosystem services in farms and their supply chains.

Potential Biocontrol Agent

Spiny snout mite (Neomolgus capillatus) is a potential biocontrol agent for clover flea (Sminthurus viridis) a white clover pest on dairy farms in warmer and wetter parts of New Zealand In the 1990s this mite was introduced from Brittany France into Tasmania for clover flea control Results during the release programme were highly promising and subsequent anecdotal farmer reports indicate widespread decreases in damage As N capillatus is a predatory mite and already known to attack nontarget organisms habitat specificity will determine whether it could be introduced into New Zealand without risk to native insects To assess this pastures on nine of the original Tasmanian release farms and adjacent nontarget habitats ranging from bush wetlands eucalypt stands to sand dune country were sampled in April 2014 Litter samples were collected heat extracted and mite species identified Neomolgus capillatus was found at effective densities in pastures that had good clover cover Where present it displaced Bdellodes spp mites that are ineffective against clover flea No N capillatus were found in the nontarget habitats all of which lacked clover and contained other predatory mites including Bdellodes spp Therefore the preference by N capillatus for lush pastures makes it an excellent prospect for introduction as a biocontrol agent into clover flea prone regions of New Zealand

Abstract Background Landscape composition has the potential to foster regulating ecosystem services such as pollination and biocontrol in temperate regions. However, most landscape studies do not take pesticide use into account even though it is the main control strategy worldwide and has negative impacts on beneficial insects. Moreover, few studies have explored these combined effects in smallholder cropping system with diverse landscapes and small cultivated fields. Methods We assessed the effect of semi-natural cover and pesticide use on pollinator and herbivore abundances and functions in 9 fields in the Ecuadorian Andes through participatory experiments with smallholder farmers. We performed a path analysis to quantify the effects of landscape and pesticide use on herbivory, pollination and ultimately yield. Results Pesticide use significantly reduced pollinator abundance but had no significant effect on pest abundance. Similarly, we found non-significant effects of landscape composition on either herbivory and pollination. The study also provides new information on understudied Andean lupine’s pests and pollinators, whose application for small farmers is discussed. Finally, we hypothesize that peculiarities of tropical smallholder cropping systems and landscapes could explain the non-significant landscape effects on insect-based processes, which calls for more research in places outside the well-studied temperate region. Conclusions Landscape composition did not show any significant effect on pest and pollinator while pesticide use decreased the abundance pollinators, but with no significant effect on yield. This study also provides information about Andean lupine reproduction and overcompensation mechanisms that could be of interest for local farmers and researchers of this understudied crop.
