“…Tachinid flies (Tachinidae) and big-eyed bugs (Geocoridae), two important natural enemy taxa, ranked third and fourth, respectively, in relative abundance. Previous studies have shown that buckwheat and sweet alyssum attract a diversity of natural enemies [12,41,42]. In this study, adult C. maculata were more frequently observed on buckwheat alone and on the mixture of buckwheat and sweet alyssum than on sweet alyssum alone.…”

“…Global interest in ecological intensification [10,11], and, more specifically, on sustainable pest management, has reinforced the importance of biodiversity conservation in agro-ecosystems [12]. From a pest management perspective, boosting populations of naturally occurring enemies of arthropod pests via habitat diversification has been advocated as a more sustainable alternative to chemically-based pest control [2,13,14,15,16].…”

Habitat manipulation through the incorporation of non-crop plants such as trap crops (to lure pests away from the cash crop) and insectary plants (to provide resources for natural enemies) into agro-ecosystems is an ecological approach to pest management. In a field-scale study, we quantified the effects of integrating the use of trap crops with insectary plants as a novel method to control pest herbivores in an organic cabbage agro-ecosystem. We hypothesized that pests would be concentrated in the trap crop habitat and suppressed by insectary-subsidized natural enemies in situ. We documented arthropod abundance (both adults and immature stages) associated with (1) two insectary plant species (sweet alyssum, Lobularia maritima, and buckwheat, Fagopyrum esculentum) either alone or in combination; (2) a trap crop mixture of mighty mustard (Brassica juncea), red Russian kale (Brassica oleracea var. acephala), and glossy collards (Brassica oleracea var. italica), and (3) cabbage cash crop (Brassica oleracea var. capitata). Trap crops were more attractive to pests than the cash crop. On a per-plant basis, densities of the herbivores Evergestis rimosalis, Trichoplusia ni, and Plutella xylostella were 154, 37, and 161× greater on the kale trap crop than on the cabbage cash crop, and 54, 18, and 89× greater on the collards trap crop than on the cash crop. Insectary plants contributed to the consumption of pests that aggregated on the trap crop. Parasitism of E. rimosalis by the braconid wasp Cotesia orobenae was significantly increased, and the abundance of eggs and larvae of the predatory coccinellid beetle Coleomegilla maculata was greater on the trap crop in the presence of insectary plants compared to trap crops that lacked insectary plants. The ‘Botanical Triad’ of cash crop, trap crop, and insectary plants represents a new type of agro-ecosystem manipulation that integrates ecosystem service providers (e.g., predators and parasitoids) within the cropping system.

Buckwheat is a plant with high sustainable potential. The sustainable agronomical potential is demonstrated by a very long and continuously cultivation, especially in Asia and Eastern Europe. Buckwheat could be found in a high number of traditional recipes and contribute to the health of populations through theirs high content of fibres, high quality proteins and many functional ingredients as antioxidants. In Romania buckwheat it is consumed in reduced quantity but could be used to formulate some functional food which could contribute to the population’s health and baking industry sustainability. We investigated the effects of replacement of wheat flour with 10%, 20% and 30% buckwheat flour. We evaluated the rheology and bread characteristics. At low level of wheat flour replacement positive effects could be observed but at 30% replacement of wheat flour the dough rheology and bread characteristics were severely affected. The taste and specific volume were most affected. We consider that buckwheat has a real potential to be use in the formulation of functional food and is a sustainable ingredient for bread baking.

“…However, insectary plants may differ in their attractiveness to beneficial arthropods. For example, buckwheat (Fagopyrum esculentum) is quick to flower and its floral resources can attract a diverse range of beneficial insects (Platt et al, 1999;Ambrosino et al, 2006, Tavares et al 2015; whereas cowpea (Vigna unguiculata) has extra-floral nectaries (Pate et al, 1985) which attract beneficial arthropods. However, insectary plants may need to be used in conjunction with other pest management tactics to have a perceptible impact on pests being targeted and cash crop yield.…”

In 2013 and 2014, different mulching systems were investigated for their potential to suppress above and below ground pests, and enhance beneficial arthropods and soil health in green onion (Allium cepa) plantings. Three types of mulch systems (organic, living and solarization mulch) were evaluated and compared. Green onions were grown in four pre-plant treatments: 1) organic mulch generated by flail mowing a sunn hemp (Crotalaria juncea) cover crop (SH) followed by a no-till cropping system, 2) soil solarization (Sol), 3) sunn hemp-solarization mulch in which the sunn hemp was incorporated into the soil followed by soil solarization (SHSol), and 4) bare ground with insecticides (BG). Sol, SHSol and BG were practiced in conventional tilled system. SH (in 2013 and 2014) and SHSol (in 2014) treatments included strips of buckwheat and cowpea along the crop border to serve as living mulch or insectary plants. Green onion plants in SH had lower thrips and leaf miners damage than other treatments in both study years. When insectary borders were added to SHSol in 2014, thrips and leaf miners damages were also reduced in SHSol compared to Sol and BG. Incidence of purple blotch was reduced in SH and SHSol treatments in 2014. The SH treatment contained an increased abundance and richness of detritivores, predatory arthropods, parasitoids and beneficial free-living nematodes (particularly bacterivores and fungivores). Although weeds and initial populations of plant-parasitic nematodes were lower in solarization (Sol, SHSol) than other treatments, green onion yield was greatest in SH organic mulch systems in both study years. Overall, the integration of surface organic, living and solarization mulches into a green onion agroecosystem provided multiple ecosystem services including suppression of above and below ground pest organisms.
