Abstract:
... In 2003, Laricobius nigrinus Fender was introduced into the eastern United States as a biological control agent of the hemlock woolly adelgid (Adelges tsugae Annand). Following its release, it was discovered that L. nigrinus was hybridising and producing viable progeny with Laricobius rubidus LeConte, a species native to eastern North America. Recently, Laricobius osakensis Montgomery and Shiyake ...

Abstract:
... Clubroot is a serious threat to cruciferous crops in Shanghai, China, and Trichoderma harzianum T4 (T4) has shown good efficiency for its control. In this study, T4 was applied alone or in combination with the fungicide cyazofamid or Bacillus subtilis XF-1, respectively, in a pot experiment to determine its efficiency of controlling clubroot. The control efficiency of T4 (79.3%) was significantly ...

Abstract:
... We characterised a novel holotype cry gene (cry1Hc1) harboured in BN23-5 Bt strain which was isolated from soil samples in Sichuan, China. In this study, the full length of the cry1Hc1 gene was cloned from the strain. The cry1Hc1 gene was inserted into a shuttle vector (pSTK) and expressed in an acrystalliferous mutant Bacillus thuringiensis HD73 ⁻. In this transformant, cry1Hc1 was expressed and ...

Abstract:
... Peristenus spretus Chen et van Achterberg (Hymenoptera: Braconidae), a parasitoid of the plant bug Apolygus lucorum (Hemiptera: Miridae), has been studied for use in augmentative biological control in China. Under laboratory conditions, we explored the development, survival, age-specific and potential lifetime fecundity, oviposition period and progeny sex ratio of P. spretus reared at six constant ...

Abstract:
... The mullein bug, Campylomma verbasci (Meyer-Dür) (Hemiptera: Miridae), exploits both plant and animal resources. The aim of this study was (1) to evaluate the quality of different plant, animal and mixed diets (i.e. plant material or prey from the overwintering host, the summer host or the laboratory rearing) for the development and survival of mullein bug, and (2) to evaluate if the suitability o ...

Abstract:
... A preliminary study to evaluate the possibilities of biological control procedures against parasites affecting livestock reared in a care farm has been conducted. Adults with mental disabilities were involved in spreading the spores of the filamentous fungus Mucor circinelloides directly onto the faeces, or as a food additive. In the first assay, the spores were sprayed directly onto the faeces of ...

Prey capture and food scavenging activities of Oecophylla longinoda were monitored through regular weekly samplings during two consecutive years (2009–2010) in a large mango orchard of the Borgou Department of Benin, West Africa, a main mango production area located in the Sudan agro-ecological zone. In both years, interspecific competition with other ants occurred mainly during the dry season (Ja ...

Abstract:
... Bacillus sphaericus binary toxin displays a specific toxicity towards Culex spp. larvae. Resistance of Culex quinquefasciatus to B. sphaericus is associated with the reduction or absence of 66-kDa α-glucosidase, a binary toxin receptor, in larval midgut microvilli. In this study, long double-stranded RNA (dsRNA) targeting the α-glucosidase gene was used to suppress the expression of α-glucosidase ...

Abstract:
... The fungal diversity structures of soils that are suppressive and non-suppressive to Sclerotinia sclerotiorum were characterised and screened for fungal strains antagonistic to the S. sclerotiorum pathogen. Soil suppressiveness was associated with a particular fungal diversity structure. Principal component analysis showed that antagonism by fungal species in suppressive soils was associated with ...
