Abstract

Stored grain products are damaged by various types of insects during preservation of T. castaneum and lesser grain borer are most dangerous insect of preserved food. Rhyzopertha dominica is inner feeder and influences the wide variety as good as high quality of grains. Spinosad insecticide are very potent to manipulate the stored grain pest. Current research work was performed in the Department of Entomology, University of Agriculture, Faisalabad. Five concentrations 0.01%, 0.02%, 0.03%, 0.04%, 0.05% along with one control treatment of Spinosad was formed in hundred ml of purified water from standard dilutions and 2, 4, 6, 8, 10% concentrations of each plants were prepared. Treatments were applied to check their possible toxic effects against T. castaneum and R. dominica. The data were recorded after 24, 48 and 72 hours, treatment means were compared with the help of (THSD) test. Spinosad gave maximum mortality 89.77% as compared to plant extracts lemon grass and tobacco 38.55% and 40.00% against lesser grain borer. Spinosad gives maximum mortality 87.27% as compared to plant extract lemon grass and tobacco 34.55% and 29.09% against red flour beetle.

Highlights

Rhyzopertha dominica and Tribolium castaneum (Herbst) cause great financial losses of stored wheat grains
In which mortality of Tribolium castaneum was maximum after 72hrs at 10% dose and maximum mortality recoded was 34.55% after 72hrs, while effects of Nicotiana tabacum against R. dominica was recoded were maximum mortality was 40% at 10% dose
The present research was conducted to assess the resistance in Rhyzopertha dominica (F) and Tribolium castaneum against insecticide Spinosad and plant extract tobacco and lemon grass

Summary

Introduction

Rhyzopertha dominica and Tribolium castaneum (Herbst) cause great financial losses of stored wheat grains. Herbst is extremely frequent and mainly critical insect of preserved goods in all over the world and it is mostly present in warehouses, mills, stored grains and granaries. Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), red flour beetle, is one of the major preserved cereals pests reported to cause damage to broad choice of items such as spices, nuts, dried fruits, cacao, flour, peas, beans and grains, but crushed cereal food stuffs like coat are their favorite food [3]. Spinosad a commercial bacterial insecticide, from the actinomycete microbes Saccharin polypore Spinosad [4]. They were reported to be efficient against R. dominica on 11-13% moisture wheat
