“…Pathogens can be used as biocontrol agents to manage insect pests (Lacey et al 2001) and studies of pathogens and their efficacy for the control of C. cinctus have reported some success (Piesik et al 2009;Wenda-Piesik et al 2006. However, many pathogens seem to occur as secondary parasites of dead larvae and, therefore, lack potential as agents for the biological control of C. cinctus.…”

Biology and integrated management of wheat stem sawfly and the need for continuing research

The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is historically one of the most important economic insect pests in the northern Great Plains of North America. Within this geographical region, the areas subjected to greatest attack are southern Alberta and Saskatchewan, southwestern Manitoba, eastern and northern Montana, North Dakota, northern South Dakota, and western Minnesota. Cumulative grain-yield losses and annual economic losses associated with this pest can exceed 30% and $350 million, respectively. Solid-stemmed cultivars of common wheat, Triticum aestivum L. (Poaceae), tolerant of infestation, are critical for C. cinctus management, but outbreaks of this pest continue to occur even after six decades of cultivar development. Furthermore, chemical control (a primary control option for other cereal (Poaceae) insect pests) has proven ineffective; this underscores the need to integrate resistant cultivars into a comprehensive integrated pest management program. We provide overviews of wheat stem sawfly biology, recent advances in applied research, the efficacy and integration of cultural and biological management strategies, and future directions for global research activities to manage wheat stem sawfly.

“…This is because linalool is well known as a defense compound in plants by either direct toxicity (Weaver et al 1991, Davoudi et al 2011) or repellency (Muller et al 2009, Dekker et al 2011 as well as an attractant for natural enemies of pests (Kessler andBaldwin 2001, Du et al 1998). The release of greater amounts of linalool from wheat and barley plants induced by C. cinctus larval feeding, after pathogen infection or after mechanical injury are well documented (Piesik et al 2006a(Piesik et al , 2006b(Piesik et al , 2009(Piesik et al , 2011(Piesik et al , 2013. A greater understanding is needed of the role of odor and contact chemoreceptors (Gress et al 2013, Robertson et al 2018) used by C. cinctus populations (Lesieur et al 2016) to assess and adapt to new host plants.…”

Wheat stem sawfly, [Cephus cinctus (Hymenoptera: Cephidae)], females display complex behaviors for host selection and oviposition. Susceptible hollow stem wheat (Triticum aestivum L.) cultivars release a greater amount of attractive compound, (Z)-3-hexenyl acetate and receive a greater number of eggs compared to resistant solid stem wheat cultivars. However, barley (Hordeum vulgare L.) is becoming a more common host for C. cinctus in Montana. Therefore, how do host selection and oviposition behaviors on barley cultivars compare to what happens when encountering wheat cultivars? To answer this question, we carried out greenhouse experiments using two barley cultivars: ‘Hockett’ and ‘Craft’. Between these cultivars at Zadoks stages 34 and 49, we compared host selection decisions using a Y-tube olfactometer, compared oviposition behaviors on stems, and counted the number of eggs inside individual stems. In Y-tube bioassays, we found a greater number of C. cinctus females were attracted to the airstream passing over ‘Hockett’ than ‘Craft’ barley cultivars. Although the frequencies of oviposition behaviors were similar between these cultivars, the number of eggs was greater in ‘Hockett’. Volatile profiles indicated that the amount of linalool was greater in the airstream from ‘Craft’ than in ‘Hockett’ at Zadoks 34 while the amount of (Z)-3-hexenyl acetate was greater in airstream from ‘Hockett’ at both Zadoks 34 and 49. These results suggest that volatiles of barley plants influenced host selection behavior of ovipositing C. cinctus females, while other discriminating behaviors do not differ between cultivars.

“…Fungal phytopathogens induce changes in the metabolite profiles of plants and the degree of defense against herbivorous insects (Ako et al, 2003;Poelman et al, 2008;Tack et al, 2012;Gols, 2014). Fungal infection in plants can also affect the natural enemies of herbivores, which are guided by chemical signals from plants (Cardoza et al, 2002;Piesik et al, 2009;Desurmont et al, 2016;Eberl et al, 2018). For example, when F. verticillioides (Peñaflor and Bento, 2019) interacts with the Borer-Cotesia Complex, it modifies the entire mechanism and gives rise to a new Borer-Cotesia-Fusarium Complex.…”

Sugarcane multitrophic interactions: Integrating belowground and aboveground organisms

Sugarcane is a crop of major importance used mainly for sugar and biofuel production, and many additional applications of its byproducts are being developed. Sugarcane cultivation is plagued by many insect pests and pathogens that reduce sugarcane yields overall. Recently emerging studies have shown complex multitrophic interactions in cultivated areas, such as the induction of sugarcane defense-related proteins by insect herbivory that function against fungal pathogens that commonly appear after mechanical damage. Fungi and viruses infecting sugarcane also modulate insect behavior, for example, by causing changes in volatile compounds responsible for insect attraction or repelling natural vector enemies via a mechanism that increases pathogen dissemination from infected plants to healthy ones. Interestingly, the fungus Fusarium verticillioides is capable of being vertically transmitted to insect offspring, ensuring its persistence in the field. Understanding multitrophic complexes is important to develop better strategies for controlling pathosystems affecting sugarcane and other important crops and highlights the importance of not only studying binary interactions but also adding as many variables as possible to effectively translate laboratory research to real-life conditions.
