Entomopathogenic nematodes (EPNs) from the Heterorhabditidae and Steinernematidae families are well-known biocontrol agents against numerous insect pests. The infective juveniles (IJs) are naturally occurring in the soil and their success in locating and penetrating the host will be affected by extrinsic/intrinsic factors that modulate their foraging behavior. Characterizing key traits in the i...

1. Two common species of acorn barnacle, Chthamalus montagui and C. stellatus , with similar resource needs, occur together on rocky shores of NW Europe but differ in their adult distribution over two environmental gradients, wave exposure and vertical height on the shore. 2. A sampling programme was undertaken over 2 years to determine the causal mechanisms of this differential distribution. T...

Mid-water plankton collections commonly include bizarre and mysterious developmental stages that differ conspicuously from their adult counterparts in morphology and habitat. Unaware of the existence of planktonic larval stages, early zoologists often misidentified these unique morphologies as independent adult lineages. Many such mistakes have since been corrected by collecting larvae, raising...

We report the first records of Aedes fumidus and Ae. amesii from India based on collections made in mangrove forests of Bhitarkanika in Orissa, Sunderbans, in West Bengal, and Andaman and Nicobar Islands. Collection details include date, location, material examined, larval habitat, and associated species.

After a pelagic larval phase, settlement-stage coral reef fish must locate a suitable reef habitat for juvenile life. Reef noise, produced by resident fish and invertebrates, provides an important cue for orientation and habitat selection during this process, which must often occur in environments impacted by anthropogenic noise. We adapted an established field-based protocol to test whether re...

Larval habitats of Armigeres subalbatus were delineated in urban and rural areas of Pondicherry. Survey of various potential mosquito breeding habitats revealed that septic tanks were the typical breeding habitat in both areas and the proportion was significantly higher in urban areas. The productive status of septic tanks differed in different months and the overall proportion breeding Ar. sub...

Atmospheric CO2 levels have been increasing at an unprecedented rate due to anthropogenic activity. Consequently, ocean pCO2 is increasing and pH decreasing, affecting marine life, including fish. For many coastal marine fishes, selection of the adult habitat occurs at the end of the pelagic larval phase. Fish larvae use a range of sensory cues, including sound, for locating settlement habitat....

Aristotelia subericinella, previously known from Ankara, Kahramanmaraş, Siirt, Van, Amasya and Bursa, is recorded for the first time in Bitlis province. Astragalus sp. (Leguminosae) suggested as new larval host-plant of species. Pupa, adult, female genitalia habitat pictures are illustrated. Information on distribution species mentioned.

Background Enterobacter cloacae bacterium is a known symbiont of the most Anopheles gut microflora and nominated as a good candidate for paratransgenic control of malaria. However, the population dynamics of this bacterium within An. stephensi and its introduction methods to the mosquitoes have not yet been explored. Methods Enterobacter cloacae subsp. dissolvens expressing green fluorescent ...

A case of myiasis due to Musca domestica describes in Pseudocerastes persicus for the first time. The snake was found in Bari Karafs, Kashan, Iran, with a lesion on its body. Fourteen live larvae of M. domestica removed from its wound. This is the first report of a new larval habitat of M. domestica.
