Bioassays were carried out to evaluate the effect of sub-lethal concentration (LC50) of mesoporous silica nanoparticles (MSNs), cinnamon oil encapsulated with silica nanoparticles (CESN), cinnamon oil and silica gel on some biological parameters of the 6th instar larvae of Corcyra cephalonica.

A series of novel sulfide derivatives containing 1,3,4-oxadiazole and pyridine were synthesized, characterized, and tested for their antibacterial activity against tobacco bacterial wilt and rice bacterial blight and for insecticidal activity toward diamondback moth. The results showed that some compounds had good insecticidal and bactericidal activity, e.g.

The relationship between the predation rate of the C. fuscipennis and the prey densities was negative correlation (R is between 0.70 and 0.98), but between the number prey killed and the prey density is positive correlation. The searching time prey of the C. fuscipennis decreased when the prey densities increased that was confirmed by the negative correlation (R between 0.85 and 0.98). The reduviid C. fuscipennis bred by the C. cephalonica in laboratory and they can use for biological control some pests of vegetables (P rapae, S. litura and P. xylostella) in Vietnam.

Our main purpose was to evaluate the expression of plastic and evolved genes involved in ecological speciation in the noctuid moth Spodoptera frugiperda, the fall armyworm (FAW); and to demonstrate how host plants might influence lineage differentiation in this polyphagous insect. FAW is an important pest of several crops worldwide, and it is differentiated into host plant-related strains, corn (CS) and rice strains (RS).

Eight isolates of entomopathogenic fungi were evaluated as dried conidia against the rice moth, Corcyra cephalonica. In bioassays two isolates of Beauveria bassiana (BbGc and BbPs) and one isolate of Metarhizium anisopliae (MaPs) consistently gave high mortality to C. cephalonica larvae. Formulations in either kaolin, talc or tapioca flour (20 % w/w a.i.) thoroughly mixed with long grain rice in plastic cups (8 cm diameter by 5 cm) gave complete larval mortality by the 12th day of treatment.

Nine experimental dietary formulations (T1-T9) were prepared which composed of rice, wheat, sorghum, rice + groundnut, wheat + groundnut, sorghum + groundnut, rice + sesamum, wheat + sesamum and sorghum + sesamum as base diet to rear and maintain the rice moth, Corcyra cephalonica under laboratory conditions. All the diets were fortified with baker’s yeast @ 5 g, wettable sulphur @ 5 g, and Streptomycin sulphate @ 50 mg.

The study was carried out to construct the life table and to study the age dependent reproduction of the predatory bug Orius bifilarus feeding on fictitious host, eggs of rice meal moth, Corcyra cephalonica (Stainton) (Lepidoptera: Galleriidae) and on its natural host, Thripspalmi Karny (Thysanoptera: Thripidae) (collected from cucumber) under controlled conditions (25 ± 1°C, 65 ± 5% RH). Themean durations of the pre, post and oviposition periods were 4.3, 1.4 and 14.2 days on C. cephalonica eggs and 4.1, 2.1 and 16.4 days on thrips, the difference being non-significant.

Rice is one of the world’s most important crops. Thus, it is necessary to improve it by genetic transformation. IR64 is a highyielding and disease-resistant variety, but it is sensitive to abiotic stresses, mainly salinity and drought.

Molecular orbital calculations (AM1 type) were performed on the geometry optimized structures of various farnesal isomers and methyl esters of farnesoic acids. It has been found that the major component, E, E-farnesal, of the sex-pheromone for the rice moth, Corcyra cephalonica Stainton is chemically the most exothermic and stable of all the farnesal isomers.
