Abundance of sucking insect pests on some flowering plants in relation to weather parameters

The study was conducted from November 2017 to May 2018 in the experimental field at Gazipur, Bangladesh investigate incidence of sucking pests namely gladiolus thrips Teniothrips simplex, tuberose aphid Aphis craccivora, marigold Neotoxoptera oliveri, and dahlia mealybug Plannococcus citri on their cultivated host plants relation temperature, relative humidity rainfall. Results showed that abundance thrips, aphid, mealy bug reached peak 3rd week January, February, 1st January respectively. Among weather factors, temperature had significant negative impact whereas rainfall influence only aphid. Multiple linear regression analysis variables collectively predicted 55.9%, 75.9%, 44.5%, 34.6% abundances mealybug, J. Sci. Ind. Res.56(4), 241-248, 2021
