Cytoplasmic incompatibility (CI) has been proposed as a major mechanism by which certain strains of Wolbachia to invade and persist in host populations. However, mechanisms that underlie the invasion and persistence of non-CI strains are less well understood. Here, we established a spider mite Tetranychus phaselus population multiply infected by Cardinium as well as two distinct lineages of Wol...
Efficient control of Tetranychus cinnabarinus (B.) is in challenge worldwide. Herein we report the use of an amphiphilic block copolymer, poly(ethylene oxide)-b-poly(caprolactone) (PEO–PCL), as a micellar carrier to make formulations of ricinine, a water insoluble botanical pesticide, and the tests of their physical properties and moreover the acaricidal activity on Vigna unguiculata (L). Compa...
Parameter estimation for the functional response of predator-prey systems is a critical methodological problem in population ecology. In this paper we consider a stochastic predator-prey system with non-linear Ivlev functional response and propose a method for model parameter estimation based on time series of field data. We tackle the problem of parameter estimation using a Bayesian approach r...
Phytopathogens and herbivores induce plant defences. Whereas there is evidence that some pathogens suppress these defences by interfering with signalling pathways involved in the defence, such evidence is scarce for herbivores. We found that the invasive spider mite Tetranychus evansi suppresses the induction of the salicylic acid and jasmonic acid signalling routes involved in induced plant de...
The research is based on the unique collections of tropical and subtropical plants MBG. Phytosanitary monitoring was carried out in laboratory «Tropical Subtropical plants»: Orangery, glass greenhouse Korean greenhouse. As a result phytosanitary complex MBG, next pests were identified: Trialeyrodes vaporariorum Westw.; Pseudococcus affinis Mask.; Diaspis boisduvalii Sign.; Tetranychus urticae L...
Population abundance of red spider mite, Tetranychus urticae Koch., was studied in cucmber, ribbed gourd, bitter gourd, snake gourd, aroids and teasle gourd and efficacy of four new acaricides were tested against this pest in brinjal at the farmer’s field of Norsingdi during 2009-2010. At the same time, the spatial distribution of this pest in brinjal crop was also studied. Results indicated th...
We investigated the ability of transgenic torenia (Scrophulariaceae) plants to resist fungi and arthropod herbivores. Torenia hybrida cv. Summerwave Blue was manipulated to produce Arabidopsis agmatine coumaroyltransferase (AtACT). This catalyses the last step in the biosynthesis of hydroxycinnamic acid amides (HCAAs) which function in defence. Transgenic plants accumulated substantial HCAAs, p...
