The brown planthopper Nilaparvata lugens (Stål) is the most serious pest of rice across the world, especially in tropical climates. N. lugens nymphs and adults were exposed to high temperatures to determine their critical thermal maximum (CTmax), heat coma temperature (HCT) and upper lethal temperature (ULT). Thermal tolerance values differed between developmental stages: nymphs were consistently less heat tolerant than adults.

The hydel project will cause loss of biodiversity and significant environmental impact

London: The Spider-Man web, which helps him snare bad guys and swing among the city’s skyscrapers, is closer to reality, say scientists who have created genetically modified silkworms which can spi

Student researchers and Mumbai residents, Rajesh Sanap and Zeeshan Mirza — both aged 23, have discovered two new species of a genus of trapdoor spiders from the southern Western Ghats.

Thirty years ago, if you were walking along the coast of the Netherlands and picked a two-spot ladybug off the leaf of a European lime tree, chances were that the bug would be red with black spots.

Establishing a direct link between climate change and fluctuations in animal populations through long-term monitoring is difficult given the paucity of baseline data. We hypothesized that social wasps are sensitive to climatic variations, and thus studied the impact of ENSO events on social wasp populations in French Guiana. We noted that during the 2000 La Niña year there was a 77.1% decrease in their nest abundance along ca. 5 km of forest edges, and that 70.5% of the species were no longer present.

Parasitoid disturbance populations in agroecosystems can be maintained through the provision of habitat refuges with host resources. However, specialized herbivores that feed on different host plants have been shown to form host-specialized races. Parasitoids may subsequently specialize on these herbivore host races and therefore prefer parasitizing insects from the refuge, avoiding foraging on the crop.

This May Help Raise Tweaked Bugs To Fight Insect-Borne Diseases And Control Pests

Researchers on Sunday reported initial signs of success from the first release into the environment of mosquitoes engineered to pass a lethal gene to their offspring, killing them before they reach
