New record of Aulacophorafoveicollis on Clerodendrum indicum (L.) Kuntze from North East India

摘要

Aulacophora foveicollis, a polyphagous pest of more than 81 plant species is known for its voracious feeding habit. Studies on occurrence and population density of this pest were carried out under field conditions at Assam Agricultural University, Jorhat. Correlation studies revealed that population density of A. foveicollis showed significant negative correlation with maximum temperature and significant positive correlation with evening relative humidity. Multiple regression equations were developedfor A. foveicollis to predict their seasonal incidence under the agro climatic conditions of Jorhat.
