Remote sensing can be applied to optimize efficiency in pest detection, as an insect sampling tool. This efficiency can result in more precise recommendations for decision making in pest management. Pest detection with remote sensing is often feasible because plant biotic stress caused by herbivory triggers a defensive physiological response in plants, which generally results in changes to leaf reflectance. Therefore, the key objective of this study was to use hyperspectral proximal remote sensing and gas exchange parameters to characterize peanut leaf responses to herbivory by Stegasta bosqueella (Lepidoptera: Gelechiidae) and Spodoptera cosmioides (Lepidoptera: Noctuidae), two major pests in South American peanut (Arachis hypogaea) production. The experiment was conducted in a randomized complete block design with a 2 × 3 factorial scheme (two lepidopterous species and 3 categories of injury). The injury treatments were: (1) natural infestation by third instars of S. bosqueella, (2) natural infestation by third instars of S. cosmioides, and (3) simulation of injury with scissors to mimic larval injury. We verified that peanut leaf reflectance is different between herbivory by the two larval species, but similar among real and simulated defoliation. Similarly, we observed differences in photosynthetic rate, stomatal conductance, transpiration, and photosynthetic water use efficiency only between species but not between real and simulated larval defoliation. Our results provide information that is essential for the development of sampling and economic thresholds of S. bosqueella and S. cosmioides on the peanut.

AbstractHelicoverpa gelotopoeon, the South American bollworm, is a polyphagous pest of the Heliothinae complex that causes damage to soybean, cotton, and chickpea crops. Some species within this complex have developed resistance to genetically modified crops and insecticides, which has led to increased interest in their genetic diversity and population structure. The objective of this study was to characterize biological and reproductive parameters of two populations of H. gelotopoeon collected in two different provinces of Argentina. Intra- and inter-population crosses revealed that H. gelotopoeon populations from both regions of Argentina did not present evidence of pre-zygotic and post-zygotic incompatibility, suggesting that Tucumán and Córdoba populations of H. gelotopoeon belong to a single wide-ranging species. Our data support the occurrence of substantial gene flow between H. gelotopoeon populations, probably due to the widely documented, long-range migratory capacity of Heliothinae species.

A new noctuid species, Apamea yunnana sp. n. is described from the yunnan Province, S China. The moth is superficially similar to A. ferrago (Eversmann) and to the recently described A. nekrasovi Mikkola, Varga & Guylai but differs from these in the details of the forewing pattern and more so in the structure of genitalia. The adult and the male genitalia of the new species are illustrated.

The taxonomy of five South American species of Dargida Walker currently allocated in Leucania Ochsenheimer (four species) and in Lasionycta Aurivillius (one species) is revised. Leucania roseilinea (Köhler, 1947), Leucania phaeoneura Hampson, 1913, Leucania mocoides Dognin, 1897, Leucania alboradiata (Hampson, 1905) and Lasionycta radiata (Köhler, 1966), are here combined with the genus Dargida Walker for the first time (comb. nov.). Two new synonyms are proposed, Leucania roseilineoides Poole, 1989 is an objective junior synonym of Borolia roseilinea Köhler, 1947 (syn. nov.) (ICZN 51.4), and B. lilloana Köhler, 1947 is a subjective junior synonym of Leucania phaeoneura Hampson, 1913 (syn. nov.). Lectotype for Borolia lilloana is designated to ensure nomenclatural stability and recognizability of the taxon. All species are redescribed and discussed, and the habitus and male and female genitalia (when available) are given, as well as an updated geographical map.
