TL;DR: The insect hormone activity of ponasterones A, B and C isolated from the plant, Podocarpus Nakaii HAY, has been examined using the house-fly and silkworm as test organisms and all three showed very high activity.

TL;DR: Firm conclusions concerning the host range and ecological adaptations of the two parasitoids cannot be drawn until detailed studies have been conducted countrywide, especially at lower altitudes where Chilo partellus (Swinhoe) and Sesamia calamistis Hampson (Lepidoptera : Noctuidae) predominate.
Abstract: The species composition of maize stemborers and prevalence of their natural enemies at five highveld (g 1200 m) sites were studied by random sampling of borer life stages in maize fields. Busseola fusca Fuller (Lepidoptera : Noctuidae) was the dominant species and constituted 99 % of all larvae and pupae sampled during the study. Cotesia sesamiae Cameron (Hymenoptera : Braconidae) was the most abundant and widely distributed parasitoid reared from B. fusca larvae, followed by Sturmiopsis parasitica (Curran) (Diptera : Tachinidae). Two hyperparasitoids, Aphanogmus fijiensis (Ferriere) (Hymenoptera : Ceraphronidae) (from C. sesamiae cocoons) and Dendrocerus rodhaini (Bequaert) (Hymenoptera : Megaspilidae) (from S. parasitica puparia) were recorded. Preliminary data on the occurrence of C. sesamiae and S. parasitica suggested that these two parasitoids complement each other by partially partitioning their niche and thus minimizing competition. However, firm conclusions concerning the host range and ecological adaptations of the two parasitoids cannot be drawn until detailed studies have been conducted countrywide, especially at lower altitudes (l 900 m a.s.l.) where Chilo partellus (Swinhoe) (Lepidoptera : Pyralidae) and Sesamia calamistis Hampson (Lepidoptera : Noctuidae) predominate.

TL;DR: Six new species that are closely related to S.’nonagrioides, an important pest of maize with a wide area of distribution that covers most of Africa and extends to the south of Europe and western Asia are described.

TL;DR: In this article, the complete mitochondrial genomes of nine species of the family Bombycidae were presented for the first time, based on these genomes, four dataset partitions and three gblocks parameter settings, phylogenetic relationships among the families were reconstructed using maximum likelihood and Bayesian inference methods.
Abstract: The family Bombycidae (sensu Minet, 1994) is a diverse group of species belonging to the superfamily Bombycoidea. It is an economically important group of moth species, containing well‐known silk‐producing insects, as well as many pests of agriculture and forestry. The morphology‐based hypothesis of Minet (1994) on the composition of Bombycidae is in conflict with subsequent phylogenetic hypotheses for the superfamily based on nuclear genes. In this paper, the complete mitochondrial genomes of nine species of Bombycidae are presented for the first time. Based on these genomes, four dataset partitions and three gblocks parameter settings, phylogenetic relationships among Bombycidae were reconstructed using maximum likelihood and Bayesian inference methods. Bombycidae was confirmed as a polyphyletic group, with the traditional subfamilies Prismostictinae and Oberthueriinae forming a single well‐supported clade that is distant to Bombycinae. The phylogenetic relationships within Bombycoidea were supported as ((((Bombycinae, Sphingidae), Saturniidae), (Prismostictinae, Oberthueriinae)), Eupterotidae).
