As pathogenic bacterial species are becoming more resistant to commonly used antibiotics, it is essential for new antibiotics to be developed. A family of resazurin (Rz)-based compounds, resazomycins, was discovered to be highly effective antimicrobials a... see more

Rice (Oryza sativa L.) is an important food for more than half of the world’s population. Globally, rice is grown on approximately 160 million hectares with an average annual production of 740.96 million tonnes. Salinity is an important abiotic factor for... see more

Sitophilus oryzae L. causes significant damage during storage of agricultural products. The use of synthetic pesticides renders effective results in the short term, but has also caused pest resistance and environmental pollution. Integrated pest managemen... see more

SummaryThe development of the stink bug Cyptocephala alvarengai Rolston (Hemiptera: Pentatomidae) was studied on rice panicles under laboratory conditions. Adults were collected in rice fields in Goianira, Goiás, Brazil. The number of eggs per egg mass ra... see more

For poikilothermic groups such as insects, the capacity to adapt to different temperature regimes is particularly important for survival. To investigate the possible role of heat shock proteins (Hsps) in the invasive pest, the rice water weevil (Lissorhop... see more
