Answer : 1. "invasive insect species"
Explanation :

Recently the Union Agriculture Minister revealed in the Rajya Sabha that Thrips parvispinus, an invasive insect, has displaced the native chilli thrips in Telangana and Andhra Pradesh. This omnivorous insect affects various crops including drumstick, pigeon pea and mango. Originally reported in India in 2015, Thrips parvispinus has spread globally, causing economic losses and viral infections. Heavy rainfall leads to increased pest infestation, causing flower drop, reduced fruit production, posing a threat to horticultural crops amid changes in agricultural practices and climatic conditions.
