Diversity of insects on bitti stands (Vitex cofassus)

Diversity and Abundance of Insects in Wukari, Taraba State, Nigeria

A field survey was conducted in Wukari, Taraba State to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). Sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. Insects recovered were wet preserved in 70% ethanol except butterflies and moths. Representativ...

Selected Aquatic Insects Can Reduce Stands in Water-Seeded Rice

Previous research at the Texas AgriLife Research and Extension Center at Beaumont on water-seeded rice revealed the possibility that one or more unknown aquatic invertebrate species have been responsible for dramatically reducing rice stands. Preliminary experiments show that there is zero or small reductions in the rice stand of plots when treated with insecticide applied to rice seed, applied...

Genetic diversity of plantations and natural stands of Avicenna marina across northern coast of Persian Gulf

The coasts of Imam Khomeini port are one of the most important hot spots of mangrove plantations across Iranian coast of Persian Gulf and Sea of Oman, so this is very important to conserve this valuable ecosystem. For this purpose, 75 individual from 3 populations, keeping the minimum distance of 30 to 50 meters from each other, has been collected and investigated using 15 ISSR markers. This st...

Phenotypic plasticity and diversity in insects.

Phenotypic plasticity in general and polyphenic development in particular are thought to play important roles in organismal diversification and evolutionary innovation. Focusing on the evolutionary developmental biology of insects, and specifically that of horned beetles, I explore the avenues by which phenotypic plasticity and polyphenic development have mediated the origins of novelty and div...
