SUMMARYThe most important technological needs and farmers' problems in agricultural entomology were identified by analysis of data collected from farmers in Tamil Nadu, India. This showed that damage due to leaf hoppers in rice was the most important research need and that due to brown plant hoppers in rice was the most important extension problem.

The present study investigated the biology and morphometric analysis of rugose spiralling whitefly (RSW), Aleyrodicus rugioperculatus on coconut under mini net house condition at Department of Agricultural Entomology, Tamil Nadu Agricultural University-Coimbatore during 2019-2020. The biology of rugose spiralling whitefly was studied by clip cage method and morphometrics were done using Leica image analyser. Total lifecycle of rugose spiraling whitefly was 56.23 ± 2.20 days. Developmental period of egg, nymphal, pupal and adult period was 8.47 ± 0.26, 17.46 ± 0.76, 10.30 ± 0.29 and 20.00 ± 1.00 days, respectively. In morphometrics, Length and width of egg (0.31 ± 0.01 mm and 0.11± 0.02 mm), nymphal (0.94 ± 0.01 mm and 0.82 ± 0.01 mm), pupal (1.23 ± 0.01 mm and 1.00 ± 0.01 mm) was recorded. A nymphal parasitoid, Encarsia guadeloupae can be potential natural enemy for effective management of rugose spiraling whitefly.

Though Alfred Binet was a prolific writer, many of his 1893–1903 works are not well known. This is partly due to a lack of English translations of the many important papers and books that he and his collaborators created during this period. Binet’s insights into intelligence testing are widely celebrated, but the centennial of his death provides an occasion to reexamine his other psychological examinations. His studies included many diverse aspects of mental life, including memory research and the science of testimony. Indeed, Binet was a pioneer of psychology and produced important research on cognitive and experimental psychology, developmental psychology, social psychology, and applied psychology. This paper seeks to elucidate these aspects of his work.

SummaryRadiobiological and cell biological knowledge is increasingly used to further improve local tumour control or to reduce normal tissue damage after radiotherapy. Important research areas are evolving which need to be addressed jointly by nuclear medicine and radiation oncology. For this differences of the biological distribution of diagnostic and therapeutic nuclides compared with the more homogenous dose-distribution of external beam radiotherapy have to be taken into consideration. Examples for interdisciplinary biology-based cancer research in radiation oncology and nuclear medicine include bioimaging of radiobiological parameters characterizing radioresistance, bioimage-guided adaptive radiotherapy, and the combination of radiotherapy with molecular targeted drugs.

The development of the Jewish religious movement "Khabad" and its organizations in the first quarter of the twentieth century - one of the important research problems, which is still practically not considered in the domestic Judaica. At the same time, this problem is relevant in connection with the fact that the religious movement "Khabad" during the twentieth century became the most widespread and influential area of Judaism in Ukraine and throughout the world.

Three species of parasitoids viz., Telenomus dignus Gahan, Trichogramma japonicum, Ishii and Tetrastichus schoenobii Ferriere were recorded from the egg masses of rice yellow stem borer, Scirpophaga incertulas (Walker) in a field study. The extent of parasitism was high during Rabi (43.33 – 93.33 %) and low during Kharif (0 - 40.00 %). Parasitism by T. dignus was maximum in October (50.00 %), T. japonicum, in November (23.08 %) and T. schoenobii in February (55.55 %). dignus and T. schoenobii in combination parasitized maximum number of egg masses (41.82 %). Multiple parasitism by the three species was high in December (8.33 %) and January (7.14%). Parasitic potential was maximum, when T. schoenobii alone parasitised the egg masses followed by T. dignus and T. schoenobii in combination. Host density in the field influenced the extent of parasitism.
