JOURNAL OF PLANT PROTECTION RESEARCH Vol. 53, No. 3 (2013) DOI: 10.2478/jppr-2013-0045 EFFECT OF PLANT OILS ON THE INFESTATION OF RHYZOPERTHA DOMINICA (FAB.) IN WHEAT, TRITICUM AESTIVUM LINN. Kailash Chand Kumawat*, Bhanwar Lal Naga Department of Entomology, Shri Karan Narendra College of Agriculture (SKRAU), Jobner (Rajasthan)-303329, India Received: April 20, 2012 Accepted: August 8, 2013 Abstract: Six oil treatments, viz., Neem (Azadirachta indica A. Juss), Castor (Ricinus communis), Karanj (Pongamia pinnata), mustard (Brassica juncea), Eucalyptus (Eucalyptus melanophloia) and Taramira (Eruca sativa) were evaluated at three dose levels (0.1, 0.5, and 1.0% v/w) against the lesser grain borer, Rhyzopertha dominica (Fab.) infesting wheat, Triticum aestivum Linn. An untreated check (the control) was maintained for comparison. The maximum protection was provided by Neem oil at 1.0 per cent (no adult emerged up to 270 days) followed by castor oil and Taramira oil at 1.0 per cent (no adult emerged up to 90 days of treatment). The maximum number of adults were recorded in the grain treated with Eucalyptus oil used at 0.1 per cent (9.3–22.0), Karanj oil at 0.1 per cent (6.0–20.7), and castor oil at 0.1 per cent (2.0–23.0). The maximum grain damage was recorded with use of Eucalyptus oil at 0.1 per cent (28.7–64.7), Karanj oil at 0.1 per cent (18.7–60.0%), and Eucalyptus at 0.5 per cent (18.0–58.0%). No grain damage was recorded in 1.0 per cent Neem oil-treated grain, for up to 270 days. -

Novel Bacteriocyte-Associated Pleomorphic Symbiont of the Grain
Okude et al. Zoological Letters (2017) 3:13 DOI 10.1186/s40851-017-0073-8 RESEARCH ARTICLE Open Access Novel bacteriocyte-associated pleomorphic symbiont of the grain pest beetle Rhyzopertha dominica (Coleoptera: Bostrichidae) Genta Okude1,2*, Ryuichi Koga1, Toshinari Hayashi1,2, Yudai Nishide1,3, Xian-Ying Meng1, Naruo Nikoh4, Akihiro Miyanoshita5 and Takema Fukatsu1,2,6* Abstract Background: The lesser grain borer Rhyzopertha dominica (Coleoptera: Bostrichidae) is a stored-product pest beetle. Early histological studies dating back to 1930s have reported that R. dominica and other bostrichid species possess a pair of oval symbiotic organs, called the bacteriomes, in which the cytoplasm is densely populated by pleomorphic symbiotic bacteria of peculiar rosette-like shape. However, the microbiological nature of the symbiont has remained elusive. Results: Here we investigated the bacterial symbiont of R. dominica using modern molecular, histological, and microscopic techniques. Whole-mount fluorescence in situ hybridization specifically targeting symbiotic bacteria consistently detected paired bacteriomes, in which the cytoplasm was full of pleomorphic bacterial cells, in the abdomen of adults, pupae and larvae, confirming previous histological descriptions. Molecular phylogenetic analysis identified the symbiont as a member of the Bacteroidetes, in which the symbiont constituted a distinct bacterial lineage allied to a variety of insect-associated endosymbiont clades, including Uzinura of diaspidid scales, Walczuchella of giant scales, Brownia of root mealybugs, Sulcia of diverse hemipterans, and Blattabacterium of roaches. The symbiont gene exhibited markedly AT-biased nucleotide composition and significantly accelerated molecular evolution, suggesting degenerative evolution of the symbiont genome. The symbiotic bacteria were detected in oocytes and embryos, confirming continuous host–symbiont association and vertical symbiont transmission in the host life cycle. -
Effect of Host Age on Progeny Production of Theocolax Elegans
Kasetsart J. (Nat. Sci.) 48 : 587 - 597 (2014) Effect of Host Age on Progeny Production of Theocolax elegans (Westwood) (Hymenoptera: Pteromalidae) Reared on Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae) Bonginkhosi E. Dlamini* and Weerawan Amornsak ABSTRACT Five host ages of Maize weevil, Sitophilus zeamais (Motschulsky) reared on brown rice were examined for progeny production of Theocolax elegans (Westwood). Brown rice kernels infested with S. zeamais were exposed to a mated female of T. elegans after 13, 15, 17, 19 and 21 d following S. zeamais introduction. Host stages were determined by measuring head-capsule widths from all the host ages. There was a signifi cant difference (P < 0.05) in T. elegans progeny production among the different host ages. Total progeny, total female progeny and total male progeny produced by 19-day-old S. zeamais larvae were signifi cantly higher (P < 0.05) compared to the other host ages. Progeny of T. elegans raised on 19-day-old S. zeamais larvae had a higher female to male ratio compared to the other host ages. Sitophilus zeamais larvae after 13, 15–17 and 19–21 d were found to be second, third and fourth instars, respectively. It was concluded that T. elegans can develop on the second, third and fourth instar larvae of S. zeamais. However, 19-day-old (fourth instar) S. zeamais larvae produced more T. elegans progeny with a higher female to male ratio.

Volatiles emitted by the host’s food would be the first signals used by parasitoids in the host location process and are thought to play an important role in host habitat location. In this study, the olfactory responses of Theocolax elegans (Westwood), a Pteromalid wasp that parasitizes immature stages of stored-product insect pests developing inside cereal or leguminous grains, to volatiles emitted by healthy wheat grains, their hexane extracts, and different doses of three individual compounds previously identified in cereal grain odors were investigated in Y-tube olfactometer and Petri dish arena behavioral bioassays and electroantennogram recordings. In Y-tube olfactometer bioassays, odors from healthy wheat grains and their hexane extracts were attractive to both sexes of T. -

The cuticular hydrocarbons from winged and wingless morphs of Choetospila elegans, a larval ectoparasite of several internal-feeding stored product beetle pests, were characterized. 2. All four morphs share the same cuticular hydrocarbons, with the major components being n-alkanes (C21-C33). 3. The minor components are 3-, ! 1- and 13-methyl branched alkanes and Z-10-monoenes. 4. Two-way analysis of variance (sex and wing morph) shows that males and females have the same profiles, whereas four components showed significant differences between wingtype morphs. 5. Only one of these four hydrocarbons (n-C31) was a major component. 6. The cuticular hydrocarbons of larvae of the lesser grain borer, Rhyzopertha dominica, were also characterized. 7. Although the beetles' major components were the same n-alkanes as those found on the adult parasites, their minor components were different. 8. Thus, the beetle larvae have no alkenes, but instead have 3-, 11-, 13- and 15-methylbranched alkanes, as well as a series of 11,15-dimethylalkanes. -

Sci., 38: 29–34. A laboratory experiment was carried out on stored wheat infested by the stored product mite Acarus siro and beetle Oryzaephilus surinamensis. The initial infestation was 150 mites of A. siro and 15 beetles of O. surinamensis per 1 kg of wheat. The predatory mite Cheyletus eruditus and parasitoid Cephalonomia tarsalis were added in the ratio 1:20 and 1:12, repectively. Three combinations were tested: (1) mites and (2) beetles separately, and (3) mites and beetles together. The experiment ran for three months at 22°C and 75% RH. The pests were suppressed by their antagonists in all combinations. Synchronous application of both natural enemies resulted in better control of O. surinamensis through an enhanced effect of both antagonists.

ABSTRACT Powders of neem seed Kernel (Azadirachta indica A. JUSS.), bush tea (Hyptis suaveolens L. poit.), Jatropha (Jatropha curcas L.), bitter melon (Momordica charantia L.) and Mahogany (khaya senegalensis Desr.) were applied at 0.5, 1.0. 1.5 and 2.0g per 20g of sorghum grain. Cypermethrin (2.0%) as control check was applied at 0.12g/20g and evaluated for toxicity against Rhyzopertha dominica Fab. on stored sorghum grains. Jatropha leaf, Mahogany stem bark and neem seed kernel powders at all concentrations recorded 76.67% and above mortality of adult R. dominica as cypermethrin. A. indica, J. curcas and K. senegalensis suppressed oviposition and reduced adult emergence of F2, offsprings. Sorghum grain damage and weight loss were highly reduced and so protect by A indica at 0.5g, while J.curcas and K. senegalensis were both effective at 1.0g and 2.0g for grain damage and weight loss prevention respectively up to 150 days of storage. -
