The study revealed the occurrence of cabbage leaf webber, Crocidolomia binotalis (Zeller) (Lepidoptera: Crambidae) as one of the serious pests of Brassica oleracea var. capitata, B. o. var. botrytis, B. o. var. gongylodes, B. o. var. acephala and B. rapa. This constitutes first report of C. binotalis on Brassicaceae vegetable crops from Kashmir Valley. Some field observations related to the local distribution, host-plant range and nature & extent of damage in respect of C. binotalis on host brassicae crops, have also been recorded.
A new species of genus Inbioia is described from the Kashmir Himalayas, India. Descriptions supplemented with high quality images, distribution maps and identification key to the known species of genus Inbioia are presented. This is also the first record of genus Inbioia from India.

Die Wespengattung Ampulicomorpha Ashmead, 1893 (Hymenoptera: Chrysidoidea: Embolemidae) ist in allen zoogeographischen Regionen weit verbreitet, war für Indien bisher aber noch nicht nachgewiesen. In der vorliegenden Studie wird die Gattung mit A. nepalensis Olmi, 1997 zum ersten Mal für Indien gemeldet. Diese Art war bisher nur aus Nepal, Vietnam und Tadschikistan bekannt.
Walnut is one of the most important fruits, which has been defined as a "Superfood" in recent years. It is infected by a wide array of insect pests. Among these pests, the walnut weevil is a destructive one. Its adults feed on flowers and buds while its larvae feed inside the fruits and are extremely destructive in causing premature dropping. We report two generations of walnut weevil in a year and only a single larva per fruit. Adults emerge from the soil in April and feed on walnut leaf buds, petioles of leaves, and floral buds. Adult females lay 1-2 eggs on fruits, mainly in May and early June, hatch in 4.9±0.74 (SD) days and 4.5±0.97 days in the first and second generations. They develop through three instars and the total developmental time lies in the range of 46-55 days (49.1±2.51). The adults of the second generation undergo overwintering to avoid harsh environmental conditions. Comprehension of biology, life cycles, and the nature of damage aids in keeping track of specific insect pests at the proper time.
