Globally, around 2000 plant species are used against pest control. The utilization of botanicals is considered the most economic
and biodegradable methods for the control of stored grains pests. Therefore, the current study was carried out to investigate the
repellency potential of five botanicals against Callosbruchus maculatus F. in Haripur, Pakistan. The concentrations of Azadirachta
indica L., Nicotiana tabacum L., Melia azedarach L., Nicotiana rustica L., and Thuja orientalis L. were, i.e., 0.5, 1.0, 1.5, 2.0, 2.5,
and 3.0% in four replicates to establish contact effects. The data were recorded after 1, 2, 3, 6, 24, 48, 72, and 96 hours. The
repellency effect of these plant species against C. maculatus were increased in both the time- and dose-dependent manner, and
highest effect was observed at 72 h. In addition, the repellency effect was 91% for A. indica (class: V), 86% M. azedarach, 82%,
N. tabacum (class: V), 79% N. rustica (class: IV), and 75% T. orientalis (class: IV) at 3% concentration against C. maculatus.
Furthermore, following 96 hours’ exposure to treatment the sensitivity response of insects decreases as the time interval
increases, i.e., 86% A. indica (class: V) was followed by 71% M. azedarach (class: IV), 65% N. tabacum (class: IV), 61%
N. rustica (class: IV), and T. orientalis 57% (class: III) repellency at highest concentration of 3%. The current study concluded
that A. indica and M. azedarach can be incorporated for the management of C. maculatus and these plant species might be
helpful in the productions of new biopesticides.
1. Introduction
The practice of using plant extracts as biopesticides or
medicines is well known [1]. As many as 2000 plant spe-
cies are in use globally in the control of insect pests. Local
people adopt more economic and biodegradable method
used as different plant part extracts as pesticides against
stored products [2]. However, the effectiveness or use of
biopesticide increases as pest management in field and
stored product pests [3].
Among the stored products, insect pests, the Genus
Callosbruchus causes annual losses to different stored
