The use of interval censored data to assess the timing of early field infestation of fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae) in maize fields por Guimapi, R.A., Nordskog, B., Hjelkrem, A.G.R., Klingen, I., Tepa-Yotto, G., Tamò, Manuele, Thunes, K.H.

“…Early time of ovipositing fall armyworm after sowing was recorded in field experiments. By using temperature-based models to predict phenological development for maize and fall armyworm, combined with analytical approaches for time-to-event data with censored status, we estimated that about 210 accumulated Degree Days (DD) is needed for early detection of neonate larvae in the field. …”

Communication interference in sympatrically occurring moth species por Juárez, María Laura, Ruiz, María Josefina, Fernandez, Patricia Carina, Goane, Lucía, Villagrán, María Elvira, Arce, Osvaldo Ernesto Antonio, Armiñana, Arturo, Páez Jerez, Paula Gabriela, de la Vega, Marcelo Horacio, Vera, María Teresa, Groot, A.T.

“…We also explored whether other co‐occurring species are attracted to these pheromone blends. Our field experiments showed that the addition of Z11‐16:Ald alone or in combination with Z9‐14:Ald inhibited trap catches of H. gelotopoeon males and that this inhibition depended on the concentration of these compounds. …”

Wheat traits and the associated loci conferring radiation use efficiency por Li, Yibo, Fulu Tao, Yuanfeng Hao, Jingyang Tong, Yonggui Xiao, He Zhonghu, Reynolds, Matthew P.

“…Wheat (Triticum aestivum L.) radiation use efficiency (RUE) must be raised through crop breeding to further increase the yield potential, as the harvest index is now close to its theoretical limit. Field experiments including 209 wheat cultivars which have been widely cultivated in China since the 1940s were conducted in two growing seasons (2018–2019 and 2019–2020) to evaluate the variations of phenological, physiological, plant architectural, and yield-related traits and their contributions to RUE and to identify limiting factors for wheat yield potential. …”
