In 1984 Bannai and Ito conjectured that there are finitely many distance-regular graphs with fixed valencies greater than two. In a series of papers, they showed that this is the case for valency 3 and 4, and also for the class of bipartite distance-regular graphs. To prove their result, they used a theorem concerning the intersection array of a triangle-free distance-regular graph, a theorem t...

Abstract Fall armyworm ( Spodoptera frugiperda ), a highly destructive and fast spreading agricultural pest native to North South America, poses real threat global food security. In this paper, explore the dynamics implications of fall outbreak in field maize biomass, we propose new dynamical system for biomass interaction via Caputo fractional-order operator, which is not only nonlocal operato...

Both orchard and adjacent native vegetation harboured adult western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), from early spring until fall. Frankliniella occidentalis made up the great majority of adults collected in flowers of most plant species sampled, including apple. Other species found on apple flowers included Anaphothrips obscurus Müller, which live...

Five new species associated with the inflorescences of Macaranga trees are described in the Asian genus Dolichothrips Karny. Four of these, chikakoae, eriae, fialae and utae, are from the Malaysian region where they are involved in the pollination of these trees. The fifth, franae, is described from the Hawaiian Islands but is probably introduced from Southeast Asia, and this species appears al...
