“…Among the five different maize cultivars, it was noticed that 'Ronimi' was the affected cultivar; this might be due to the cultivars morphological character like compact whorl, soft stem and long internodes. This is in agreement with Bamaiyi and Joan (2011).…”

The studies were carried out at the School of Agricultural Sciences and Rural Development, Medziphema campus, Nagaland University during 2019. The experiment was laid out in a Split Plot Design (SPD) having three replications. The cultivars viz., Zarsi, Sipho, Ronimi, Khoi and HQPM-1 were sown on 3 different dates i.e., 6th March, 21st March and 5th April. Among the five cultivars used the local cultivar ‘Sipho’was found to be the most tolerant and performed better than the composite variety ‘HQPM-1’ and the different dates of sowing, 5th April was found to be the most successful with the least infestation by Chilo partellus. The maize sown on 21st March recorded the highest grain yield (4.12 t/ha). Among the four cultivars and one composite variety evaluated, the highest grain yield was recorded from cultivar Sipho with 4.13 t/ha, while the lowest from cultivar Ronimi with 3.11 t/ha.

“…These results corroborate with those of Ramkumar and Tanweer Alam (2017) on the efficacy of chlorantraniliprole and carbofuran in maize. Bamaiyi and Joan (2011) observed that the tunnel damage was relatively less in carbofuran 3G treated plots as observed now. The exit holes caused by the adult emergence were less in chlorantraniliprole 18.5SC (1.8) followed by spinosad (1.9) and chlorantraniliprole 0.4G (2.3) Ramkumar and Tanweer Alam (2017).…”

Efficacy of insecticides against spotted stem borer Chilo partellus (swinhoe) in sorghum was studied at the institutional farm, Regional Agricultural Research Station, Nandyal, Andhra Pradesh during rabi 2016-17 and 2017-18. Deadhearts were observed to be less with spinosad (4.0%) followed by carbofuran 3G (4.10%), chlorantraniliprole 18.5SC (4.95) and chlorantraniliprole 0.4G (4.86) applied at 25 days after sowing. The least infestation at 40 days after sowing was observed with chlorantraniliprole 18.5SC (6.2%), spinosad 45SC (7.0%), chlorantraniliprole 0.4G (7.3%) and carbofuran 3G @ 10 kg/ ha (8.0%). Lesser number of larvae in the stem tunnel were observed with chlorantraniliprole 18.5SC/0.4G, spinosad, carbofuran 3G, phorate 10G and flubendiamide. The incremental benefit cost ratio was maximum with carbofuran 3G (5.2:1), followed by chlorantraniliprole 0.4G (4.8:1) and chlorantraniliprole 18.5SC (4.2:1).

“…Population of pest insects living in an environment where some habitats are occasionally destroyed may achieve its maximal growth rate when they spread the risk of local extinction (Yoshimura and Jansen 1996;Jansen and Yoshimura 1998;Maslov and Sneppen 2015b). Stem borers are usually serious pests in farmlands (Hoffmann and Frodsham 1993;Sun et al 1993;Rahman et al 2004;Bamaiyi and Joan 2011). These pests are considered to be pure pests, because they do not use wild substitute host plants.…”

Long‐term persistence of agricultural pest insects by risk‐spreading dispersal

Insects are the most diverse organisms on earth consisting of more than 900 thousand species. However, only few of them are considered agricultural pests. Life history traits such as high fecundity, fast population growth, and high dispersal ability have been used to characterize agricultural pest insects. However, many other non‐pest insects also share these traits, which indicates that there has not been a decisive condition characterizing agricultural pest insects. Agricultural habitats are risky and ephemeral to pests because of pest control and harvesting. The usual arithmetic mean fitness cannot be used to measure the persistence of these pests, because the maximal mean fitness is achieved only when they exhibit no dispersal, but that leads to immediate extinction. Using a geometric mean fitness model, we propose a quantitative measure of long‐term reproductive success for agricultural pest insects. By using this approach, we can evaluate the trade‐off between long‐distance dispersal and high reproduction correctly and estimate the condition for the long‐term persistence of pest insects in agricultural habitats. We discuss some general perspectives of pest control from the proposed characterization.
