Development and demographic parameters of Fall Armyworm (Spodoptera frugiperda J.E. Smith) when feeding on rice (Oryza sativa) por Ali, Md Panna, Haque, Sheikh Shamiul, Hossain, Mohammed Mosaddeke, Bari, Md Nazmul, Kabir, Mir Md Moniruzzaman, Roy, Tapon Kumar, Datta, Juel, Howlader, Mohammad Tofazzal Hossain, Alam, Syed Nurul, Krupnik, Timothy J.

“…When the Fall Armyworm consumed maize instead of rice, there was an increase in the reproduction rate (R0), the intrinsic rate of natural increase (rm), and the finite rate of increase (λ). For instance, when FAW fed on rice, the rm value was 0.121, whereas it rose to 0.173 when FAW fed on maize. …”

Lifetime productivity of dairy cows in smallholder farming systems of the Central highlands of Kenya por Rufino, Mariana C., Herrero, Mario, Wijk, Mark T. van, Hemerink, L., Ridder, N.A. de, Giller, Kenneth E.

“…We used LIVSIM (LIVestock SIMulator), an individual-based, dynamic model in which performance depends on genetic potential of the breed and feeding. We tested the model for the highlands of Central Kenya, and simulated individual animals throughout their lifetime using scenarios with different diets based on common feedstuffs used in these systems (Napier grass, maize stover and dairy concentrates), with and without imposing random mortality on different age classes. …”
