Abstract
Bio-pesticide treated jute bags were evaluated for their insecticidal flurry against
Rhyzopertha dominica
infesting stored
wheat. The jute bags were separately treated with 2, 4, 6 and 8ml dosage of
Eugenia aromatica
oil while some bags were
deep-soaked in 100ml of the oil. Untreated bags were set as controls. The result obtained showed that the treated bags significantly
affect survival of insects as they all achieved above 55% mortality within 72hours of exposure. Moreover, it was observed that jute
bag that was deep-soaked in 100ml of
E. aromatica
had the greatest mortality effect on the beetle as it achieved 100% mortality
within 48hours of exposure. All the treated bags were found to reduce or prevent the weight loss and damage of the stored wheat after
42 days of storage. The ability of these bags to prevent the weight loss and damage of the stored wheat reduced after six months of
storage as only the deep-soaked jute bag was able to prevent seed weight loss and damage. The oil treated jute bags have no effect on
the colour, odour and acceptability of the wheat grains stored in them. The result also showed that the treated jute bags did not affect
the viability of the stored wheat after six months. Base on the result obtained, the use of
E. aromatica-
treated jute bags may serve as
an acceptable method of applying botanical pesticides in protection of stored grains.

Introduction
Rhyzopertha dominica
is an important insect pest of
wheat
Triticum
spp. This insect is a field to store pest
which its infestation on wheat has led to the reduction
in quality, quantity and marketability of this important
crop (Ileke, 2011). Use of synthetic chemical
insecticides have been the major approach to the
control of this important insect pest of wheat but the
adverse effects post by these chemical insecticides has
led researchers to find a new boulevard of controlling
the insect pest of stored products generally. Some of
the drawbacks that trimmed down the use of synthetic
chemical insecticides include pest resurgence and
resistance, lethal effects on non-target organisms, food
residues and their effect on both human and environmental
health (Garriga and Caballero, 2011; Akinneye and
Ogungbite, 2013a; Ashamo et al., 2013). Because of
the public awareness of these adverse effects,
botanical products have been relied upon as an
alternative way of controlling insect pests of stored
products as they are believed to be easily
biodegradable, ecofriendly and have low mammalian
toxicity (Zibaee, 2011). Many botanical powders and
extracts have been proved to be effective against
stored product insect pest; such botanicals include
Azadiracta indica
,
Anarcardium occidentalis,
Zanthoxylum zanthoxyloides, Aristolochia ringens,
Piper guineense, Eugenia aromatica
among others
(Boeke et al., 2001; Akinkurolere, 2007; Idoko and
Adeshina, 2012; Akinneye and Ogungbite,
2013b).
