Abstract

This study was carried out to evaluate efficiency sticky traps on attraction Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae) on strawberry plants Fragaria ananassa (L.) (Three strawberry varieties i.e. Sweet charli, Chandler and Festival) under glasshouse conditions at two locations (governorates), Nobariya (Behera governorate) and Perkash (Giza governorate) during season 2019/2020. This study contains three experiments; the first experiment aimed to evaluate the efficiency color of the sticky trap on attraction T. vaporariorum throughout comparison between four colors (yellow, red, white and blue). Results showed that the traps which have yellow color more efficiency on attractive T. vaporariorum than others which have (blue, red, and white) color, respectively. Second experiment aimed to evaluation efficiency height of the yellow sticky trap on attraction T. vaporariorum through comparison between four heights (2m, 1.5m, 1m and 0.5m) above the ground. Results showed that the trap which have 2m height above the ground more efficiency on attractive T. vaporariorum than others which have (1.5m, 1m and 0.5m) heights, respectively. Third experiment aimed to evaluation efficiency orientation of the yellow sticky trap on attraction T. vaporariorum through comparison between four orientations (North, South, East and West). Results showed that had no clearly effect of the trap orientation on attraction T. vaporariorum

Highlights

Strawberry plants, Fragaria ananassa (L.) consider one of the most important vegetable plants in Egypt and all over the world which is cultivated in the open field and under glasshouse conditions
Jian and Nick (2007) in California found that the greenhouse whitefly, T. vaporariorum has emerged as a major insect pest of many horticultural crops such as strawberry in California
When ANOVA indicates that significant differences were found, (P > 0.05) means were separated by a Least Significant Differences Test (LSD), the simple correlation (r) and regression coefficient value (b) was adopted to clarifies the change in population due to change in each of the tested factors and the mean values compared with the Least Significant Differences (LSD) as well as, SAS program (SAS Institute 1988)

Summary

Introduction

Strawberry plants, Fragaria ananassa (L.) consider one of the most important vegetable plants in Egypt and all over the world which is cultivated in the open field and under glasshouse conditions. This study was carried out to evaluate the efficiency of sticky traps on attraction T. vaporariorum on Strawberry plants F. ananassa (three strawberry varieties i.e. Sweet charli, Chandler, and Festival) under glasshouse conditions at two locations (governorates), Nobariya (Behera governorate) and Perkash (Giza governorate) during season 2019/2020.
