Abstract:
... Cardinium and Wolbachia are maternally inherited bacterial symbionts of arthropods that can manipulate host reproduction by increasing the fitness of infected females. Here, we report that Cardinium and Wolbachia coinfection induced male‐killing and cytoplasmic incompatibility (CI) when they coexisted in a cryptic species of whitefly, Bemisia tabaci Asia II7. Cardinium and Wolbachia symbionts were ...

Abstract:
... BACKGROUND: While plant glucosinolates are known to impart resistance to many insects, their role in the interactions between plants and many phloem‐feeding insects such as whiteflies are poorly understood. The whitefly Bemisia tabaci complex comprises many cryptic species that differ in the ability to utilize Brassica plants. However, whether Brassica plants‐specific traits such as glucosinolates ...

Abstract:
... Organochlorine pesticides are still widely used in many regions of the world, despite their toxic properties to many organisms, including humans, and their high environmental persistence in waters and sediments. In order to properly assess contaminant effects across trophic levels in aquatic communities, the responses of different model organisms should be investigated. Particularly for marine ben ...

Abstract:
... Kuruma shrimp Penaeus (Marsupenaeus) japonicus is a high‐value penaeid shrimp in Japanese live fish markets owing to its characteristic colour and flavour. Although this species was believed to be the single species of subgenus Marsupenaeus, the existence of two morphotypes (Form I and Form II) have been confirmed recently. Recent studies classified the native stock from Indian coast as Form II. F ...

Abstract:
... Understanding the ecological mechanisms driving the dynamics of field rotifer populations remains a challenge in ecology. Brachionus angularis (Rotifera) is preferred in such studies because of their planktonic behavior, high fecundity, and absence of cryptic species. In this study, one-year zooplankton samples were collected twice a month from a subtropical lake and the roles of abiotic and bioti ...

Abstract:
... Among tephritid fruit flies, hybridization has been found to produce local adaptation and speciation, and in the case of pest species, induce behavioral and ecological alterations that can adversely impact efficient pest management. The fraterculus species group within Anastrepha (Diptera: Tephritidae), is a rapidly radiating aggregate, which includes cryptic species complexes, numerous sister spe ...

Abstract:

Low morphological diversity among interstitial taxa makes it difficult to delimit species and their geographic boundaries based solely on morphology and molecular data often reveal cryptic species. Polygordius (Annelida, Polygordiidae) have low morphological diversity, but are unusual among interstitial species in their comparatively large size due to their elongated form, high fecundity, and pote ...

While it generally has been accepted that evolutionary pressures may drive parasitic worms to produce many small eggs to overcome the challenges of transmission, recent studies suggest wide variability in reproductive strategies among such worms. Although egg morphometrics and numbers have been reported from many species of Diplostomum, the presence of cryptic species has resulted in uncertainty i ...

Abstract:
... When using biological control against pest populations, more than one biocontrol agent might be introduced simultaneously. This could be counterproductive in the event of negative interactions between the biocontrol agents. Within and between species interactions have a strong impact on mating behaviour and reproduction, and can have an impact on the effectiveness of biological control. We studied ...
