“…Also in green cabbage cultivation, the effect of extrafloral nectar of Vicia faba L. (Fabaceae) was evaluated on the activities of Diaeretiella rapae (McIntosh), having a positive effect on female longevity and increased oviposition rate (Jamont et al, 2013). Basil also acted to improve the fitness attributes of lacewing, a generalist predator, optimizing the biological control of aphids in a greenhouse (Fang et al, 2022).…”

“…However, plant diversification must be planned, with species capable of attracting and maintaining natural enemies of interest to effectively reduce pests, without affecting the productivity of the main crop or attracting pests (Barbosa et al, 2011;da Silva et al, 2022).

Conservative biological control seeks to preserve beneficial organisms as the natural enemies of pests through habitat management. These studies aimed to measure the potential of basil (Ocimum basilicum L.) in the biological control of aphids in green cabbage (Brassica oleraceae L. var. acephala); and to evaluate the influence of the intercropping on green cabbage productivity. In an organic commercial crop of green cabbage in Águas Claras, RS, basil was used as an associated border (BB) and contrasted with plants in beds with no border (WB). We compared Aphididae density and parasitism, in the spring/summer seasons of 2016 and autumn/winter of 2017. Brevicoryne brassicae L. and Myzus persicae Sulzer (Hemiptera, Aphididae) were recorded in the green cabbage, in 2016. A mean of 13.8 ± 8.72 aphids/leaf was recorded in the WB, significantly higher than in the BB, 3.4 ± 1.83 (Tukey 5% p = 0.00002). In the 2017 season, this difference was not significant at 10.3 ± 12.73 (WB) and 6.9 ± 11.34 (BB). The mean of parasitized aphids was 2.8 ± 2.84 in WB and 9.9 ± 2.87 BB (p = 0.0041) in the spring crop and 2.9 ± 4.10 (WB) and 14.25 ± 7.3 (BB) in the winter (p = 0.0039). The association of green cabbage and basil had an area equivalence index (AEI) in 2016 = 1.07 and 2017 = 0.99 indicating that basil did not affect green cabbage yield.

“…While there are but few studies of coccinellid community dynamics in tropical annual agroecosystems (e.g. Amaral et al, 2013; da Silva et al, 2022; Fidelis et al, 2018; Sampaio et al, 2017; Sicsú et al, 2015), none have focused on the mechanisms of invasion by Ha. axyridis .…”

1. Detailed understanding of the mechanisms enabling or limiting the impacts of invasive generalist predators is needed. Harmonia axyridis is an invasive generalist coccinellid predator that may have destabilised coccinellid communities worldwide and is an excellent candidate for investigating invasion dynamics.2. We evaluated four hypotheses: (1) Nine years after being detected in Central Brazil, Ha. axyridis has dominated the coccinellid community. This is facilitated by (2) its broader aphid prey range than the other aphidophagous coccinellids, (3) its superiority as an asymmetrical intraguild predator, and (4) the invasibility of the present coccinellid community.3. We sampled the invertebrate communities associated with six organic vegetable farms in Brazil during 2017 and 2018, conducted a feeding trial to measure prey niche breadth and overlap, and estimated intra-and interspecific interaction strengths corresponding to first-order Lotka-Volterra parameters to evaluate the strength of intraguild predation and create a community matrix. 4. We found (1) Ha. axyridis comprised ≤8.3% of the coccinellid community. (2) Hi. convergens had the broadest prey niche and dominated the prey niche of Ha. axyridis. (3) We could not determine from the population data if Ha. axyridis was the dominant intraguild predator because its density was too low and constant.(4) The community matrix indicated that the present-day coccinellid community was stable. 5. We conclude Ha. axyridis has not become invasive in Central Brazil, in part because it does not have the broadest prey niche breadth and the present coccinellid community is stable to the present perturbation of Ha. axyridis.

“…18 Various studies have demonstrated the ability for supplementary floral resources to enhance the survival and activity of parasitic hymenopterans like L. japonica and G. brasiliensis. 19,20 However, to accurately assess the potential efficacy of these parasitoids for control of D. suzukii, information about their population dynamics will be particularly important. 21 If they are to be effective, the populations must reach adequate levels for control during the period where D. suzukii is causing damage or else the phenological mismatch could render them ineffective for damage control.…”

BACKGROUND: The spotted wing drosophila, Drosophila suzukii Matsumura, is a South-East Asian vinegar fly that is a serious worldwide economic threat to the small fruit industry. Typical control consists of weekly pesticide applications, which can have nontarget effects, increase residual pesticides and lead to the development of resistance within pest populations. One potential alternate method of control is the planting of aromatic intercrops to attract the natural enemies of D. suzukii and/or repel the flies directly. We intercropped strawberry rows with flowering sweet alyssum or ryegrass-clover (control) to evaluate their efficacy at mitigating D. suzukii infestation through the attraction of two specialized larval parasitoids, Leptopilina japonica (Novkovic and Kimura) and Ganaspis brasiliensis (Ihering).RESULTS: Our study did not demonstrate any significant effect of sweet alyssum intercropping on the infestation rate of D. suzukii in strawberries or parasitism level. However, we found that advanced sampling date and recorded numbers of D. suzukii larvae and parasitoids were positively correlated, indicating higher populations at the end of the strawberry-growing season.CONCLUSIONS: Sweet alyssum intercrops did not reduce D. suzukii infestation rates or increase parasitism levels, likely due to low population numbers in early season berry varieties. Aromatic intercrops may be more effective for increasing pest control in later season crops.
