The female of Bruchus nikdeli Delobel and Sadeghi, unknown until now, is described for the first time. Distinguishing characters of the female and detailed structures of the genitalia of both sexes are presented with digital photographs. The species is also recorded as a new country record from...

Combinatorial delivery of different double-stranded RNAs (dsRNAs) can result in competitive inhibition in insect pests and remains one of the obstacles in the way of future applications of the RNA interference (RNAi)-based pest control. In this study, we attempted to discover the basic competition...

Predator-prey interactions affect ecological communities. Consistent individual differences in the behavior, or animal personality, of predators and/or prey can influence inter-specific interactions. For example, high activity predators may have increased foraging success on low activity prey...

The Guild concept has been of great interest to ecologists, and widely applied in entomology, particularly to study the activity of insects in various ecosystems. However, the guild concept in storage entomology is understudied. We hypothesized that the feeding guild structure of stored grain...

A new delivery system was applied to control P. operculella based on interpolation of Lippia citriodora essential oil into PVA-nanofiber using electrospinning technique. Based on GC-MS results, geranial and (-)-spathulenol were the prevailing compounds of the essential oil. Fumigant bioassay...

Pulse beetle, Callosobruchus spp. are the major threat in legume grain (pulse) storage. They are very prolific and rapid in breeding and increasing their population within short period of time. Its infestation starts either in the field on the maturing pod and is carried to the stores with the...

The widespread use of synthetic chemical pesticides beginning in the late 1930s has contributed to the development of insecticide resistance of many important species of pest insects and plants. Recent trends in pesticide development have emphasized the use of more environmentally benign control...

The investigation was carried out at CCS Haryana Agricultural University, Hisar for two years i.e. 2016 and 2017 during June to October. During June, population of larvae of Galleria mellonella larvae started increasing till September in both years.. However, during October, the number decreased....

The red flour beetle Tribolium castaneum is one of the common pests of stored grains distributed worldwide. In this study, testing the effect of TiO₂ and ZnO nanoparticles as insecticides on adults of T. castaneum was achieved. Results showed that the high concentration of TiO₂ and ZnO...
