Gene expression changes in Maconellicoccus hirsutus in response to sublethal dose of buprofezin.

The pink or hibiscus mealybug, Maconellicoccus hirsutus, is a serious pest of grapes, jute, and mesta, causing severe yield losses in India and other countries. Chemical control remains the foremost choice for farmers to manage this pest. As insecticides break down over time due to biotic and abiotic factors, insects are exposed to varying levels of these exogenous compounds.

Identification and expression dynamics of CYPome across different developmental stages of Maconellicoccus hirsutus (Green).

Maconellicoccus hirsutus is a highly polyphagous insect pest, posing a substantial threat to various crop sp., especially in the tropical and sub-tropical regions of the world. While extensive physiological and biological studies have been conducted on this pest, the lack of genetic information has hindered our understanding of the molecular mechanisms underlying its growth, development, and xenobiotic metabolism.

A remarkable new genus of Thripinae (Thysanoptera, Thripidae) without anteocellar setae from India.

(Thripidae, Thripinae) is described from the flowers of Pouzolziapetandrasubsp.wightii (Urticaceae) found in Nandi hills, Karnataka, India. This new genus is characterised by an apomorphy, ocellar setae pairs I and II are both absent, and also has a unique discontinuous pore plate distribution, with a single circular or oval pore plate medially on abdominal sternites II and V-VII of males.

Ru(ii)-Catalyzed spirocyclization of aryl N-sulfonyl ketimines with aryl isocyanates through an aromatic C-H bond activation.

A novel one-pot strategy has been developed for the construction of spiro-isoindolinone-benzosultams through a Ru(ii)-catalyzed sequential C-C and C-N bond formation. This method is highly atom-economical and compatible with a wide range of substituents. This is the first report on the spirocyclization of 3-aryl N-sulfonyl ketimines with aryl isocyanates to produce highly rigid and pharmaceutically relevant spirocycles through a C-H bond activation.
