SELEÇÃO DE ESPÉCIES DE Trichogramma sp. EM OVOS DA TRAÇA-DAS-CRUCÍFERAS, Plutella xylostella

open access: yesRevista Caatinga, 2011
Trichogramma species are found naturally parasitizing eggs of several lepidopteran species. Among the Trichogramma species, however, there is preference for certain lepidopteran species as host. Therefore, to succeed in a biological control program using

Evaluation of diverse elite and landrace maize lines for testcross hybrid performance and combining ability under low and high phosphorus fertilization regimes

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract In the context of over‐fertilization, especially of phosphorus (P), the debate about the usefulness of applying starter fertilization to maize (Zea mays L.) must be revisited. One solution is to breed crops with an enhanced phosphorus use efficiency, which require less fertilizer yet are high‐yielding.

Comparative Genomics of the Endosymbiont Cardinium Causing Reproductive Manipulation in Encarsia Parasitoid Wasps

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
We assembled four Cardinium hertigii draft genomes: cEina3 causes cytoplasmic incompatibility, cEhis1 induces parthenogenesis, cEper2 is associated with parthenogenesis, and cEina2 infects asymptomatically. All four strains are closely related and hosted by Encarsia parasitoid wasps, but key differences exist, including their metabolic potential and ...
