Summary: The stingless bee Tetragonula pagdeni was investigated as a potential pollinator for greenhouse tomatoes in Southeast Asia. Results showed that a greenhouse with stingless bees had significantly higher fruit yield and quality compared to a greenhouse without stingless bees or pollinated by mechanical vibration. This suggests that T. pagdeni could be a beneficial alternative pollinator in tropical regions where the use of honeybees and bumblebees is challenging.

Summary: Several studies have shown that stingless bees collect hairs from the labella of Maxillaria spp., which are believed to have nutritional value. However, the labella of Maxillaria splendens alliance actually contain trichomes that lack food materials. These trichomes can be easily detached and do not function as food-hairs. Field observations of M. ochroleuca suggest that stingless bees scrape polyphenol-rich labellar tissue and use it to produce "bee glue" for nest construction and repair.

Summary: Pollinators play a crucial role in sustainable agriculture, but their efficiency depends on factors such as behavior and morphology. In this study, we compared the effects of probing time and visit frequency of different bee species on greenhouse cultivated cucumber. The results showed that the body size and morphometric characteristics of the bees varied, leading to differences in nectar probing times. The stingless bee M. bocandei was found to be a more efficient pollinator for cucumbers compared to the honeybee A. mellifera scutellata and D. schmidti.

Summary: A study compared the body size and frequency of diploid males of a widespread stingless bee in mating congregations in Merida, Mexico and surrounding rural areas, finding that males in the city were smaller and diploid males were more frequent compared to rural areas. The results suggest that urban tropical areas may have poorer colony performance for N. perilampoides due to limited resources and mating among a small number of colonies.

Summary: Compared to other types of bees, the effect of diet on the gut microbiome of Neotropical corbiculate bees is not well understood. This study found that there was an increase in gut-associated bacteria in forager bees 2 months before the first symptoms were recorded. Additionally, forager bees showed a decrease in body weight. These changes were linked to diet shifts, specifically the increase in Eucalyptus spp. pollen in the bees' guts. There was also a negative correlation between the amount of Eucalyptus pollen in diets and the abundance of certain bacterial taxa in the gut-associated microbiota.

Summary: Restoring native tropical forests is important for protecting biodiversity and ecosystem functions, but the contribution of early stages of forest regeneration to crop productivity is not well understood. A study in Brazil found that young regenerating forests have a positive association with coffee yield when there is a sufficient amount of preserved forest nearby. These findings highlight the importance of both regenerating and mature forests in supporting pollination and pest control services that affect coffee yields. It emphasizes the need for public policies to promote ecosystem restoration and ensure the long-term permanence of these new forests.

Summary: Here, we report a new occurrence of Amphidecta calliomma in the Carajas National Forest (Para, eastern Amazon) and expand the known distribution of this butterfly species. We also provide a species distribution model and compare the contribution of the new occurrence to future projections, which support further field research. The projections show an expansion of the species' distribution in the southeast portion of the Amazon Forest. Despite its wide distribution, the small number of records may indicate low detectability of A. calliomma in surveys. This study provides support for new surveys and helps fill the knowledge gap about this species, supporting its conservation.

Summary: Research shows that endogenous nitric oxide (NO) plays a regulatory role in tomato shoot architecture, fruit set, and growth. Inhibiting S-nitrosoglutathione reductase (GSNOR) in tomato promotes shoot side branching and reduces fruit size, negatively impacting fruit yield. It was also found that GSNOR inhibition results in increased protein tyrosine nitration and S-nitrosation, affecting auxin production and signaling in leaf primordia and developing ovaries of fruits.

Summary: The main cotton pest in the Americas is the cotton boll weevil. Reproductive diapause can be induced in these weevils when they feed on alternative diets. This study found that prolonged feeding on alternative diets affects the reproductive tract of female and old male weevils differently, and these individuals may not be able to reverse the atrophy of their reproductive organs even after accessing cotton squares.
