Article Synopsis
  • - Cotton production in Tanzania is highly affected by various insect pests, with potential damages reaching up to 60%, yet there's a lack of understanding about these pests' behaviors throughout different seasons and growth stages of the crop.
  • - The study conducted in Misungwi district found a total of 8,500 insect specimens collected over two growing seasons, revealing that cotton's growth stages and seasonal changes significantly impact pest abundance and diversity.
  • - The research highlights the need for developing sustainable pest management strategies to address these challenges in repeated cotton cultivation in Tanzania, which could be applicable in similar agricultural contexts.

Background: Malaria morbidity and mortality, almost entirely from , are still rampant in Africa: therefore, it is important to study the biology of the parasite and the parasite-host cell interactions. cultivation of is most useful for this purpose, as well as for investigating drug resistance and possible new therapies. Here we report that the Trager & Jensen continuous culture of can be established in a laboratory in Tanzania with minimal facilities and with modest expenditure.

Background: Red blood cell (RBC) physiology is directly linked to many human disorders associated with low tissue oxygen levels or anemia including chronic obstructive pulmonary disease, congenital heart disease, sleep apnea and sickle cell anemia. Parasites such as spp. and directly target RBCs, and surface molecules within the RBC membrane are critical for pathogen interactions.

Species diversity, abundance, and dispersion of rice stem borers in framer's fields were studied in four major rice growing areas of Kahama District. Stem borer larvae were extracted from the damaged tillers in 16 quadrants established in each field. Adult Moths were trapped by light traps and collected in vials for identification.
