Optimization of vine killing date for maximum seed-tuber yield and minimum exposure to late-season aphid vectors in potato.

Short-duration and early-bulking potato varieties are well-suited for commercial cultivation in the subtropical Indo-Gangetic plains of India. To maximize seed tuber yield, prevent late-season exposure to aphid vectors, and facilitate the timely planting of wheat crops during the season, it is essential to cut the haulms (vines) of seed potatoes at the earliest possible time. A study was conducted to standardize the optimal vine-killing date for two popular potato varieties in the north-western plains of India, and , by examining variations in seed yield across different vine-killing dates and assessing the incidence of aphid vectors transmitting potato viruses.

Genetic diversity, population structure and marker-trait associations in Indian kale ( L. gp. acephala) using cross-species microsatellite markers.

Kale is known for its exceptional nourishing and functional benefits to human body. However, it is an understudied species from genomic as well as agronomic aspects. It is important to characterize niche kale germplasms around the world to systematically conserve and utilize its genetic variability, especially for commercial traits in the interest of growers, consumers and industry.

Functional Response of Four Syrphid Predators Associated With Green Apple Aphid (Hemiptera: Aphididae) in Laboratory.

Aphis pomi De Geer, the green apple aphid, is an economic pest of apple and other rosaceae throughout the world. In the present study, functional responses of the syrphids Episyrphus balteatus De Geer, Eristalis tenax(L.), Eristalis interruptus (Poda), and Sphaerophoria scripta (L.

Qualitative and quantitative prey requirements of two aphidophagous coccinellids, Adalia tetraspilota and Hippodamia variegata.

The suitability of two prey species, Aphis pomi De Geer (Hemiptera: Aphididae) and Brevicoryne brassicae (L.), for two generalist aphidophagous coccinellids, Adalia tetraspilota (Hope) (Coleoptera: Coccinellidae) and Hippodamia variegata (Goeze), at various abundance levels was investigated under laboratory conditions. While both A.
