Additional Food Enhances the Bifurcation Structure of Predator Competition Models

Kanishka Goyal, Chanaka Kottegoda, Urvashi Verma +1

Additional food sources and predator competition are both known to impact the dynamics of predator-prey models. The Bazykin model of predator competition, with Holling type II func…

An Investigation of Additional Food Models with Generalised Functional Response

Urvashi Verma, Kanishka Goyal, Saptarshi Biswas +2

Additional food sources are often used to improve the effectiveness of predators in controlling pest populations. However, the non-symmetric structure of additional food predator-p…

An "adaptive" approach to control explosive aphid populations

Aniket Banerjee, Urvashi Verma, Satyam Narayan Srivastava +1

Classical models of aphid population dynamics are unable to explain multi-peak patterns in field populations. We consider the variable carrying capacity model (VCM), which can gene…

An additional food driven biological control patch model, incorporating generalized competition

Urvashi Verma, Kanishka Goyal, Chanaka Kottegoda +1

Additional food sources for an introduced predator are known to increase its efficiency on a target pest. In this context, inhibiting factors such as interference, predator competi…

Towards improved pest management of the soybean aphid

Urvashi Verma, Margaret Lewis, Jordan Lehman +1

The soybean aphid (\emph{Aphis glycines}) is an invasive insect pest that continues to cause large-scale damage to soybean crops in the North Central United States. The current man…

T(w)o patch or not t(w)o patch: A novel additional food model

Urvashi Verma, Aniket Banerjee, Rana D. Parshad

A number of top down bio-control models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator…
