Survival of adult beetles of maize and cowpea weevil was least on cowpea (10 g) and maize (10 g) flour treated with 3 g V. grandifolia (3.30-20%, 6.70-20%, respectively) and 3 g D. arborea (3.300-13.3%, 0.0-3.3%, respectively) compared to other treatments, which included different concentrations of the leaf powders. V. grandifolia was inhibitory to mean adult emergence of C. maculatus (7.00-9.33) and S. zeamais (8.00-9.67) compared with the control (15.00). However, D. arborea did not differ from the control. It is concluded that V. grandifolia has great potential for use as a plant-based biopesticide for controlling both weevil pests.10aSitophilus zeamais1 aEpidi, Timothy, T.1 aNwani, C., D.1 aUdoh, S.  uhttps://weevil.myspecies.info/efficacy-some-plant-species-control-cowpea-weevil-callosobruchus-maculatus-and-maize-weevil-sitophil02131nas a2200217   4500008004100000020002500041245017100066210006900237260000900306300001200315490000700327520127000334653003001604100003201634700002001666700002201686700002401708700001901732700002701751856013501778       2011                        eng d  a1560-8530; 1814-959600aMitochondrial Genetic Variation and Invasion History of Red Palm Weevil, Rhynchophorus ferrugineus (Coleoptera: Curculionidae), in Middle-East and Mediterranean Basin0 aMitochondrial Genetic Variation and Invasion History of Red Palm  c2011  a631-6370 v133 aThe Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Olivier), (Coleoptera, Curculionidae, Rhynchophorinae), is an invasive pest of palm trees. RPW has invaded Middle East and several countries of the Mediterranean Basin during the last three decades. The mitochondrial genetic variation of RPW was investigated in the Middle-East and the Mediterranean basin areas using partial sequences of the Cytochrome c oxidase sub-unit 1 (CO1) gene. A 546-base pair portion of COI gene was sequenced for 310 individuals of RPW sampled from 14 different invaded countries resulting in eight different haplotypes. Eight haplotypes were subdivided into two phylogenetic groups according to their geographic positions. The obtained genetic diversity suggested that RPW population subdivided genetically into different sub-populations under the influence of genetic drift favored by founder events. RPW followed three different routes of invasion during the last 30 years. Likely, Middle-east populations and the Mediterranean ones are originating from different geographic populations of RPW. The data reported in this paper present an interesting and useful step toward the understanding of the genetic variation and invasion history of RPW.

RAPD profiles exhibited bands between 200 to 1400 bp in length. Average genetic distances among populations ranged from 0.3 to 0.8. Genetic distances among the analyzed individuals ranged from 0.241 (between individuals from populations of Egypt&Turkey) to 1 (between individuals from populations of Japan&both Egypt, Spain&France). The Unweigthed Pair Group Method with Arithmetic (UPGMA) mean categorized the tested populations into twelve clusters. Based on results, it is suggested that there are two major routes of RPW invasion, the first is at the origin of all the populations found in Egypt and Mediterranean countries and second is at the origin of the populations found in the Arabic Peninsula, Iran and Pakistan.

The multivariate statistical techniques such as principal component analysis (PCA), linear discriminant analysis (LDA), principle component regression (PCR), partial least square (PLS) and back-propagation neural networks (BPNN) were used to evaluate the electronic nose data, respectively. The PCA and LDA results showed that the electronic nose can distinguish paddy rice with different storage time (ST) and different number of infesting insects (NI). After employing PCR, PLS and BPNN, respectively to predict the infestation index (NI&ST), the three methods all had good prediction performances. The correlation coefficient between the NI real and the three predicted values was 0.955, 0.864, and 0.996 for the PCR, the PLS and the BPNN, respectively. The correlation coefficient between the ST real and the three predicted values was 0.992, 0.852 and 0.998. BPNN model had the highest prediction accuracy. The results implied that it is possible to predict the characteristics of insect infestation in stored paddy rice from signal of electronic nose.
