“…In the present study, five weed species presented a significantly higher number of mites than the rest of the weeds: G. parviflora, B. pilosa, P. persicaria, S. cordifolia and R. sativus. These results confirmed the potential of weeds to host a great diversity and abundance of beneficial mites, which has been previously reported (Moraes et al 1993;Ferla et al 2007;Cañarte et al 2020). In the present study, 13 beneficial mite species were found in the weeds associated with the strawberry crops.…”

“…Natural vegetation in the field margins shows a relatively high diversity of beneficial insects and mites (Denys and Tscharntke 2002) and has been reported to provide alternative preys or food resources and shelter for beneficial arthropods (Ferla et al 2007;Sikorska et al 2019), although their diversity and abundance depends on the vegetal species composition on the field margins (Asteraki et al 2004). In Brazil, studies on mite fauna associated to crops demonstrated the existence of a diverse and abundant community, including families of phytophagous mites (Tarsonemidae, Tenuipalpidae, and Tetranychidae), predators (Ascidae, Blattisociidae, Cunaxidae, Erythraeidae, Iolinidae, Parasitidae, Phytoseiidae and Stigmaeidae), as well as other mites with diverse food habitats (Acaridae, Oribatidae and Tydeidae) (Moraes et al 1993;Ferla et al 2007;Cañarte et al 2020). However, the relationship between weeds, strawberry cultivars and mite fauna remains scarcely studied (De Vis et al 2006;Ferla et al 2007).…”

“…These two species are known predators of TSSM and could act as agents of natural biological control. Even though the potential of weeds for harboring predatory mite species has been demonstrated, it is important to highlight that a suitable knowledge about the interactions among weeds, mite species and crops is still required for improving biological control management (Cañarte et al 2020).…”

The presence of weeds in the margins of strawberry crops can enhance populations of predatory mites as a measure to support conservation biological control. The aims of this study were (i) to assess the composition of the acarofauna associated with strawberries and the accompanying herbaceous plants in an organic farming system, and (ii) to evaluate the possible relationships between phytophagous and predatory mites occurring in this system. Strawberry leaves and whole plants of weeds were sampled biweekly from August 2014 to February 2015 in Lapa (Paraná, Brazil). In total, 23 weed species belonging to 10 families were identified; 3768 mite individuals (from 15 families and 4 suborders) were recovered, 77% on strawberries and 23% on weeds. Abundance of predatory mites on weeds was greater than on strawberry cultivars. On strawberries, the most abundant family was Tetranychidae (84%) followed by Phytoseiidae (11.6%). In total, 16 predatory mite species from the Phytoseiidae family were identified, 13 of them occurring on strawberry leaflets. Typholodromalus aripo, Neoseiulus californicus and Typhlodromips mangleae were the most abundant mite species on strawberry leaves. On weeds, most individuals were predatory mites (59%), whereas phytophagous mites represented 17.2%. The most abundant family was Phytoseiidae (36.4%). On weeds, the phytoseiid mite T. aripo was the most abundant species, representing 34.7%. Besides being found on strawberry leaflets, T. aripo was associated with 15 weed species. Among the weeds, Bidens pilosa showed the highest values of the Shannon index (1.97), Margalef index (3.04), and Pielou's evenness index (0.95). This study emphasizes the importance of surrounding weeds as a shelter for beneficial mitefauna in strawberry fields, likely contributing to enhance conservation biological control.

“…The conservation of strips of wild plants within the cultivation area, for example, provides the permanence of natural enemies that use other foods besides their preys (Venzon et al, 2019). The cowpea consortium in succession to corn favored the diversity and the abundance of predatory mites in Jatropha curcas (Cañarte et al, 2020). The flowering plants introduced in strips can also increase the herbivore population levels, which will be food resource to the natural enemies, benefiting them in periods of scarcity of pests in the crop since it ensures their survival, fertility, and longevity and its efficiency in the pest control.…”

Biological control is a worldwide trend and has been prominent as an effective and compatible strategy for use in Integrated Pest Management programs. In Brazil, the control of these organisms using biological agents has been used in several agricultural systems, including floriculture. This paper approaches biological control from the perspective of the interaction between organisms in nature, applied as a pest management strategy. Knowledge about the dependence and reciprocity among populations in a natural environment is fundamental to understanding that this control method is nothing more than an exploiting of a natural ecological service. Considering that, for the biological control of a pest we must increase the population density of natural enemies, we report on the two main ways to achieve this increase: conservative biological control and augmentative biological control. The first is done by modifying the environment’s vegetation structure to favor natural enemies’ maintenance or their attraction to the crops. The second is done by mass rearing entomophagous and entomopathogen species with attributes that can ensure their function as control agents when released in crops. Among such agents, we emphasize those produced and marketed in Brazil for application in ornamental plants. Finally, we report on the technologies most recently employed to increase the appropriate use and the efficiency of these biological control agents.

“…Jatropha can be intercropped with other crops (Rao et al, 2017). Although intercropping enables getting revenues in the first years of the Jatropha life, it can increase the abundance and diversity of mite pests (Cañarte et al, 2020) and also pose difficulty in irrigation control to meet the needs of each plant properly despite sharing the same soil and its moisture content.…”

<i>Jatropha Curcas</i> as Marginal Land Development Crop in the Sultanate of Oman for Producing Biodiesel, Biogas, Biobriquettes, Animal Feed, and Organic Fertilizer

The present article can be regarded as a compilation of various aspects related to the cultivation and utilization of Jatropha curcas in degraded lands, which may not be very suitable for other crops. The benefits of this plant are not limited to producing biodiesel, but expand to biogas and biobriquettes. So, all three phases of fuel (liquid, gas, solid) are possible outcomes from it. Aside from fuels, the byproduct seedcake resulting from pressing the seeds can be used as a good organic fertilizer that is comparable or even better than chicken manure. After detoxification, this seedcake can be valuable feed for livestock. Along with the positive expectations, the study is balanced by also addressing negative expectations when planting Jatropha curcas for commercial applications. A seeds sample of this plant was successfully germinated in indoor condition, after applying the shell cracking pre-treatment. Special attention is paid to the Sultanate of Oman as a country whose geographic location and vast desert lands may encourage large-scale investment in Jatropha curcas for boosting and diversifying the economy.
