Diversity and potentiality of lepidopterous borer pests on mango and sapota in Andhra Pradesh.

Abstract

Studies were conducted on the incidence of borer pests on mango (Mangifera Indica) and sapota (Manilkarazapota) at Dr. YSR Horticultural University. Venkataramannagudem during 2016-2017. A fixed plot survey was carried out in both the crops indicated the presence of throe borerson mango and five borers on spools. Out of these. red banded mango caterpillar. Deanolissublimbaks (Lepidoptera: Crambidae). chiku moth, Nepkoponyzerographella (Lepidoptem: Pyrulidae)sapota budborer Anarsiaachrasella (Lepidoptera: Gelechiidae)and fruit borer, Phycitaerythrolophia (Lepidoptera: Pyralidae) were encountered as serious pests and found to feed on the fruits. Subsequently, invasive borer pests, Citripesdrattraphera(Lepidoptera:Pyralidee) on mango and seed borer, Trymalttismargarias (Lepidoptera: Tortricidae) on sapota were also recorded during the investigation. Apolyphagous borer, castor capsule borer Conogethuspuncteferalis (Lepidoptera:Crambidae) was found to attack on the fruits of mango and sapota. Furthermore, the seasonal incidence of major borers in both the crops revealed that. D.sublimbalis damage on mango fruits up to 36.54% during mango season (December to May) whereas. the sapota bud borers were active throughout the crop period with a range of 10-48% bud damage. Correlation studies with weather parameters revealed that RBMC damage had a weak correlation with temperature and humidity parameters whereas, sapota bud damage had a significant positive relationship with evening relative humidity.
