Predation on the Indian Bull frog Hoplobatrachus tigerinus (Daudin, 1802) (Anura: Dicroglossidae) by the Asian House Shrew Suncus murinus (Linnaeus, 1766) (Soricomorpha: Soricidae) from Nepal

Abstract
We present a natural history account of the first record of probable predation on the Indian bull frog, Hoplobatrachus tigerinus by the Asian House Shrew, Suncus murinus from Morang district, Nepal. The present communication provides an example of a nearly equal-sized predator-prey interaction in a natural ecosystem and provides interesting information on the natural history of these taxa.

Global scenario on human-big cats interactions and coexistence patterns- a critical review

Volume 5, Issue 1 (3-2023)
Abstract
The big cats are of paramount importance for the sustenance of ecosystems and their interaction with humans is critical for their conservation. Coexistence and tolerance of the people involved will be crucial in the conservation of these cats in the growing human-dominated landscapes. The literature review on humans and big cats' conflicts and their coexistence indicates socio-economic factors are the main driving forces in shaping human attitudes toward these cats. In contrast to the mainstream view, conflict frequency does not directly affect the tolerance capacity of stakeholders; instead, coalitions of many factors like livelihood status, religious and cultural beliefs and government intervention are involved. The review provides an evaluation of the prevalent mitigation measures and other principles that govern human-big cats conflict and sheds light on the potential of coexistence as a pro-conservation strategy.

Abstract
The present study summarizes the predators and parasitoids of two species, the mustard aphid Lipaphis erysimi (Kaltenbach, 1843) and the turnip aphid Lipaphis pseudobrassicae (Davis, 1914) infesting various food plants distributed in various states and union territories of India. These predators belong to four orders of the class Insecta: Coleoptera (Coccinellidae), Diptera (Chamaemyiidae, Syrphidae), Hemiptera (Anthocoridae, Geocoridae, Reduviidae) and Neuroptera (Chrysopidae, Hemerobiidae), and one order of class Arachnida, the order Araneae (spiders) (6 families). A total of 100 species of predators were observed to feed on the mustard aphid on 23 food plant species distributed in 26 states/union territory of India. The greatest numbers of predators of both species belong to the families Coccinellidae (47 species) and Syrphidae (27 species). Four species of predatory bugs (Hemiptera), seven species of lacewings (Neuroptera) and fourteen species of spiders are reported to prey on Lipaphis erysimi in India. Most of the tritrophic associations (triplets, predators–preys–host plants) of these predators are reported from Uttar Pradesh (98 triplets) followed by West Bengal (58 triplets), Punjab (53 triplets), Manipur (48 triplets), Tripura (40 triplets) and other states/union territories (less than 40 triplets). A total of 16 species of predators belonging to Coccinellidae, Syrphidae and Chrysopidae are reported to prey on Lipaphis pseudobrassicae only in seven states/union territory of India, mostly in Jammu and Kashmir. Two families of the parasitoids, Aphelinidae and Braconidae (subfamily Aphidiinae) parasitize L. erysimi in India. Aphelinidae is represented by 5 species distributed in seven states/union territory and Braconidae by 17 species on 20 host plants in 24 states/union territory of India. Most of the tritrophic associations (triplets, parasitoids–hosts–host plants) of these parasitoids are reported from Manipur (15 triplets) followed by Uttar Pradesh (11 triplets) and less than 10 triplets in other states/union territories. Only two identified species of Braconidae were observed to parasitize L. pseudobrassicae in India on two host plant species distributed only in Jammu and Kashmir, Karnataka and Punjab.
