The Coleoscirinae (Acari: Trombidiformes: Cunaxidae) from Pakistan are summarized in this paper. Two species of Scutascirus Den Heyer (S. pirgus Chaudhri and Akbar and S. tactus Chaudhri and Akbar), ten species of Coleoscirus Berlese (C. baptos (Chaudhri and Akbar), C. carex (Inayatullah and Shahid), C. carnus Muhammad and Chaudhri, C. comis Muhammad and Chaudhri, C. disparis Muhammad and Chaudhri, C. irroratus Muhammad and Chaudhri, C. mardi (Inatullah and Shahid), C. raviensis Afzal, Ashfaq and Khan, C. tobaensis Bashir, Afzal, Ashfaq, and Khan, and C. trudus Bashir, Afzal and Akbar), and three species of Pseudobonzia Smiley (P. ashfaqi Bashir, Afzal and Akbar, P. numida Chaudhri and Akbar, and P. parilus Chaudhri) have been previously reported. One new species of Pseudobonzia, Pseudobonzia bakeri SP N: , is herein described and illustrated. A key to the genera of the subfamily and keys to the species in each genus are given to incorporate the new species from Pakistan. Distribution records of all known species in Pakistan are also given.

Antioxidant enzyme influences germination, stress tolerance, and virulence of Isaria fumosorosea.

Hide Abstract
Antioxidizing enzymes (superoxide dismutase, catalase, and glutathione peroxidae) are important enzymatic systems used to degrade hydrogen peroxide into water and oxygen, thereby lowering intracellular hydrogen peroxide levels. Entomopathogenic fungi display increased activities of antioxidizing enzymes during growth and germination, which is necessary to counteract the hyperoxidant state produced by oxidative metabolism. We studied the influence of different carbon sources on antioxidizing enzyme production by Isaria fumosorosea to determine the importance of antioxiding enzymes induction in fungal germination, stress tolerance and virulence. Conidia produced by colonies grown on hydrocarbons showed higher rates of enzyme activities compared to the control and the enzyme activities of the conidia produced on n-octacosane were higher than all the other treatments. The lipid peroxidation activities were observed as an indicative marker of oxidative damage to cells and the lowest levels of lipid peroxidation activities were observed for n-octacosane treatment. The increased enzyme activities of n-octacosane- grown conidia were accompanied by higher levels of resistance to exogenous hydrogen peroxide, reduction in germination time and higher virulence against Spodoptera exigua. Our study has helped to identify that increased activities of antioxidizing enzymes can improve the germination and tolerance to antioxidant stress response of I. fumosorosea.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
