“…In addition, use of non-preferred cucurbit cultivars can reduce beetle damage, and is effective at farm-scale [119]. Finally, a habitat for natural enemies could be provided [113], and the role of parasitoids could be better understood and promoted [120][121][122]. The example of cultural practices replacing the role that neonicotinoid insecticides occupy in conventional systems typifies sustainable alternative with lessened off-target effects that organic agroecological pest management strategies can provide.…”

The need to improve agricultural sustainability to secure yields, minimize environmental impacts and buffer environmental change is widely recognized. Investment in conventional agriculture has supported its present yield advantage. However, organic agriculture with agroecological management has nascent capacity for sustainable production and for increasing yields in the future. Conventional systems have leveraged reductionist approaches to address pests, primarily through pesticides that seek to eliminate biological factors that reduce yield, but come at a cost to human and ecosystem health, and leave production systems vulnerable to the development of pest resistance to these chemicals or traits. Alternatives are needed, and are found in organic production approaches. Although both organic and agroecology approaches encompass more than pest management, this aspect is a pivotal element of our agricultural future. Through increased investment and application of emerging analytical approaches to improve plant breeding for and management of these systems, yields and resilience will surpass approaches that address components alone.

“…What is less clear is the exact identity of the parasitoid given the limited number of Centistes CO1 sequences available in public repositories and the difficulty in making species level identifications from larvae. Despite this lack of available sequence data, the species C. diabroticae and C. gasseni have been repeatedly described from the literature to feed on several adult species of Diabrotica and related Acalymma (Toepfer et al 2008;Smyth and Hoffmann 2010). Of these two species, C. gasseni is known from rearing experiments to be able to parasitize D. undecimpunctata but is not known from Mexico, and C. diabroticae is known from Mexico but has not been reported to parasitize D. undecimpunctata (Shaw 1995;Toepfer et al 2008).…”

Globalized trade has resulted in the incidental translocation of numerous insect species, some of which have become invasive in their expanded ranges. While rigorous inspection programs are a regular part of commodity importation, rarely if ever are the internal contents of intercepted insects examined. As part of a genetic diversity project on intercepted Diabrotica undecimpunctata beetles, we detected CO1 DNA that closely matched sequences from Centistes parasitoid wasps in 9% of our samples. The presence of internal parasitoids was confirmed through dissections and imaging, wherein the samples were morphologically consistent with Centistes larvae. Such a discovery suggests that insect translocation as part of trade can be more diverse than initially thought. The case of Centistes in imported Diabrotica may present a positive benefit specifically to agroecosystems through the biological control of pest beetles like Diabrotica. However, drawbacks from such introductions include off-target parasitism of non-pest beetles and resultant impacts to insect populations in undisturbed ecosystems. Thus, examination of intercepted insects beyond the initial species identification is warranted to better understand the potential impacts of human mediated insect translocations. Methods employing high-throughput sequencing and metabarcoding are well suited for such broad-scale identification projects where Diabrotica would be an excellent candidate for this work.

“…In our study, we show that due to the lethal hazard for bees of thiamethoxam residues coming from in-furrow applications and the lack of pest control efficiency from the seed treatments and the foliar spray, commercial applications of thiamethoxam does not currently provide a sustainable solution for squash growers, representing a dilemma that requires further research on more efficient pesticide delivery methods as well as on non-pesticide pest control measurements. The incorporation of parasitoids [60] and entomopathogenic nematodes [61,62] seems promising although they require broad development to increase efficiency and to facilitate the adoption by growers.…”

The pest control and pollinator protection dilemma: The case of thiamethoxam prophylactic applications in squash crops

et al. 2022

A major challenge in sustainable agriculture is finding solutions to manage crop-damaging pests such as herbivores while protecting beneficial organisms such as pollinators. Squash is a highly pollinator-dependent crop that is also attractive to herbivores like the striped cucumber beetle. While synthetic insecticides can provide control of insect pests, they can also affect non-target organisms such as pollinators. Thus, growers need to balance pest management with pollinator protection to ensure optimal yield. Thiamethoxam is a commonly used systemic insecticide that translocates throughout plants, leaving residues in nectar and pollen. The aim of this study was to evaluate whether there are uses of this insecticide that provides efficient pest control while minimizing pesticide pollinator exposure. Specifically, we tested how different prophylactic application methods (seed treatments, in-furrow applications, and early foliar sprays) of commercially available thiamethoxam products impact pest control, bee visitation, yield, and pesticide residues in flowers of squash crops. We found that among the different methods of thiamethoxam application, in-furrow application best prevented defoliation and resulted in the highest fruit weight and number. However, it also produced the most frequent and highest concentrations of thiamethoxam in nectar and pollen, reaching lethal levels for squash bees. Our study provides evidence that under current application methods, thiamethoxam does not provide a sustainable solution for squash growers and further research is required on more efficient pesticide delivery methods, as well as non-pesticide pest control measurements.
