Special Issue Information

Dear Colleagues,

The management of lepidopteran pests has been a constant challenge in several agricultural crops in different countries. It is known that innovative solutions for the control of lepidopteran pests have been or are being developed by several public and private companies. These innovations have changed the approach to monitoring, managing, and controlling lepidopteran pests in various agricultural crops. Given this perspective, the publication of discoveries and innovations is essential for scientific advancement in the management of these pests. Therefore, we invite researchers from public and private companies to contribute to this Special Issue.

With this Special Issue of Agronomy, we seek studies that represent innovative advances in the management of lepidopteran pests in the most diverse crops, as well as reviews that offer original perspectives on advances in the control of lepidopteran pests that attack agricultural crops.

Dr. Oderlei Bernardi

The oriental armyworm Mythimna separata (Walker) is a worldwide migratory pest that threatens food security in China. Previous studies have clarified the general migration regularity of M. separata in East Asia, but knowledge of migration routes over northeast China, especially in autumn as well as the impact by climate change in recent years, is still limited. From 2017 to 2020, we monitored the migration of M. separata in northeast China by searchlight traps and simulated moth trajectories by the HYSPLIT model. The M. separata moths had three main migration periods in northeast China, and there were obvious seasonal differences at different latitudes. The spring and summer migrants (late May to early-mid June and late July to early August) came from the southern Shandong Province and migrated to the north via Hebei/Shandong-Liaoning-Jilin-Heilongjiang. Moreover, more than half of the autumn trapped insects from late August to mid-late September migrated in the provinces where the sites are located, southward via Heilongjiang-Jilin-Liaoning. These results clarified the migration route of M. separata in northeast China and their relationship with the insect source in north China, thereby providing a theoretical basis for regional monitoring, early warning, and management of the pest.

Genetically modified (GM) soybeans expressing Cry1A.105/Cry2Ab2/Cry1Ac (event MON 87701 × MON 89788 × MON 87751 × MON 87708) and Cry1Ac (event MON 87701 × MON 89788) from Bacillus thuringiensis Berliner (Bt) are valuable technologies for managing key lepidopteran pests of soybean in South America, but do not provide stand-alone protection against Spodoptera species. Here, we evaluated the use of these Bt soybeans and their integration with insecticides for managing Spodoptera species. Cry1A.105/Cry2Ab2/Cry1Ac soybean provided reasonable levels of protection against S. cosmioides, S. albula, and S. eridania. However, S. frugiperda had higher survival on this Bt soybean, and Cry1Ac soybean showed low lethality against all species evaluated. Spodoptera larvae that survived on Bt and non-Bt soybean showed comparable susceptibility to flubendiamide and thiodicarb in diet-overlay bioassays. Regardless of soybean plant type, the field doses of flubendiamide and thiodicarb were effective in controlling surviving Spodoptera larvae. We conclude that Cry1A.105/Cry2Ab2/Cry1Ac soybean is effective in controlling S. cosmioides and S. albula, and also has reasonable control of S. eridania, but not S. frugiperda. Cry1Ac soybean provided poor control of all Spodoptera species. Nonetheless, Spodoptera larvae surviving on both Bt and non-Bt soybean were controlled by flubendiamide and thiodicarb. Thus, integrated control tactics would provide effective management of Spodoptera species in Bt soybean fields in South America. Full article

The cotton bollworm Helicoverpa armigera (Lepidoptera: Noctuidae) is a significant pest in the world and it was identified in Brazil in 2013, causing severe economic losses. Recent studies showed a significant decrease in the susceptibility of H. armigera to diamide insecticides in Brazil. Understanding the genetic basis and mechanisms of the resistance are essential to develop proactive resistance management strategies. A laboratory strain of H. armigera resistant to the phthalic acid diamide flubendiamide (Flub-R) was selected from a field-collected population to characterize the resistance. The resistance ratio of the Flub-R strain was >50,000-fold. The inheritance pattern of the resistance was characterized as an autosomal dominant trait. Flub-R showed no cross-resistance to the anthranilic diamides chlorantraniliprole, cyantraniliprole or cyclaniliprole. Susceptible strain larvae that fed on flubendiamide-treated soybean leaves at field-recommended rates were killed while heterozygotes and Flub-R larvae showed a high survival and no reduction in the leaf consumption, confirming the functional dominance of the resistance. No indication of metabolic resistance was detected. The partial sequencing of ryanodine receptor (RyR) genes covering the transmembrane II to VI did not show any amino acid mutations, indicating the presence of a non-common resistance mechanism to diamide insecticides in the Flub-R strain.
