Biopesticides from Entomopathogenic Nematodes

Karimipour Fard H. and Saeidi K. 2019. Biopesticides from entomopathogenic nematodes   Plant Pathology Science 8(1): 60-73. DOI: 10.2982/PPS.8.1.60.   In the recant decade, biopesticides with entomopathogenic nematodes (EPNs) have been developed with using different methods and materials. But the production of such biopesticides has always accompanied by some limitations such as low quality o...

Nematodes

Figure 1. Our current understanding of the phylogenetic relationships of nematodes. The main panel shows the phylogeny of the major nematode groups, information about ecological range and presence of parasites (black bars indicate definitive hosts, grey bars intermediate hosts), and some representative genera. Phylogenetic relationships within Nematoda currently rely mostly on small-subunit rRN...

Intensified Arabian Sea tropical storms

Tropical cyclones over the Arabian Sea in the pre-monsoon season (May–June) have intensified since 1997 (ref. 1, Fig. 1a) owing to significant reductions in storm-ambient vertical wind shear (VWS) in the troposphere; these reductions have decreased on average by about 3m s from the pre-1997 epoch (1979–1997) to the recent epoch (1998–2010). The authors attribute the reduction of premonsoon VWS ...
