Abstract

The desert locust, Schistocerca gregaria (Forskal) (Orthoptera: Acrididae), is the world’s most dangerous and destructive migratory pest. It is a highly voracious and polyphagous insect. Its swarms can migrate hundreds of kilometers per day and invade areas covering millions of square kilometers, causing significant and widespread crop losses. In this review, we synthesize published research and reports on the life cycle, behavior, phases of desert locust along with its damage and management. Elements of locust management include population monitoring and population prediction. However, there are difficulties involved with estimating locust populations because locust swarms are highly mobile. Control techniques for managing locust swarms include cultural control (digging, burning), baiting (scattering locust food impregnated with insecticides), dusting with insecticide, and spraying liquid insecticides (chemical or biological) using ultra-low volume (ULV) application. Effective management strategy relies on improved knowledge of pest biology, more efficient monitoring and control techniques.

Abstract

A prototype soil moisture based an automated irrigation system were developed at National Maize Research Program in 2018 to study the water requirement of drought tolerant crop genotype. The irrigation system has been controlled by Arduino UNO as a micro controller. The instant soil moisture data were collected either in Excel format or graphical format using internet of things through the programming of Global System for Mobile Communication: Subscriber Identity Module (GSM:SIM card) of Nepal Telecom. The developed automated irrigation system has found maintained the predetermined threshold soil moisture. This automated irrigation system has been developed to make applicable for drip irrigation system which has operated at low water pressure maintained by 1.5² professional-grade solenoid valve. The introduction of this automated irrigation system has developed the base for Nepalese agricultural scientist in designing and promoting irrigation technology to make Nepalese agricultural more sustainable, mechanized and productive.

Abstract

Phenological study of a fruit tree is important for timely and proper orchard management. This study was carried out in orchard located at Warm Temperate Horticulture Centre (WTHC), Kathmandu, Nepal from January to August, 2020 with the objective to identify the different timing of phenological stages in 18 different varieties of pear. Data on days from swollen bud to bud burst, swollen bud to green cluster, swollen bud to white bud, swollen bud to bloom, swollen bud to petal fall, swollen bud to fruit set, fruit length, and fruit diameter were recorded. The phenological and fruit traits were found highly significant. The shortest flowering period (days from swollen bud to petal fall) was observed in varieties Sinko and Yakumo (13.33 days) and the longest period was found in Pharping local (Green) (35.00 days) followed by Pharping local (Brown) (34.00 days). The longest fruit (58.80 mm) was recorded in Anjou followed by Bartlett (52.90 mm) and Yakumo (49.80 mm). Similarly, the highest fruit diameter (57.60 mm) was recorded in Anjou followed by Yakumo (55.80 mm) and Atago (51.60 mm). On the basis of total variability, pear varieties were grouped into five distinct clusters. Cluster 2 showed that Anjou had the highest fruit length and fruit diameter. Cluster 5 illustrated that the longest flowering period was observed in the Pharping local (Green) followed by Pharping local (Brown). Based on phenological traits Sinko and Yakumo and based on fruits traits Anjou were found potential varieties for cultivation under warm temperate region of Nepal.
