In a study published in the Journal of Experimental Biology, researchers from Kobe University found that hawkmoth larvae and pupae produce defensive sounds when stimulated. These sounds are released through respiratory openings and resemble snake warning signals, potentially helping the insects evade predators.
A study published in PLOS Computational Biology reveals that different cell types and variation within these cells play a crucial role in muscle remodeling during Drosophila development. The findings show that sarcolytes, hemocytes, and fat body cells work together to break down larval muscles and scatter the fragments.
Researchers found that the caterpillars' cycles interact with natural controls like viral disease, and they're highly adapted to their environment. Outbreaks can be predicted and damage controlled, but the exact timing is linked to specific factors.
The Antarctic midge employs a unique survival mechanism by undergoing quiescence in its first year and obligate diapause in its second. This adaptation allows the insect to quickly resume development when temperatures rise.
A new study found that monarch pupae can survive and produce adults for up to seven weeks in the winter, with a 49.4% success rate in pupal eclosion. The study suggests a potential adaptation to warmer winters and offers an alternative to traditional overwintering methods.
A parasitic wasp has evolved to perfectly target a common fruit fly pest, demonstrating key principles of ecologically driven evolution. The Trichopria drosophilae wasp overcomes the pest's defenses by producing venom and specialized cells that speed up digestion and increase nutrition for its young.
Researchers discovered that ant pupae secrete a fluid that is consumed by both adults and larvae, highlighting the interconnectedness of different developmental stages within an ant colony. The fluid, derived from molting, is rich in nutrients and psychoactive substances, essential for larval growth and adult metabolism.
The study's findings provide a foundation for developing efficient protein isolation techniques from insect powders, which could help address global hunger and malnutrition issues. Insect-based protein sources are rich in essential amino acids and offer a sustainable alternative to traditional farming methods.
Larvae of horseradish flea beetles use glucosinolates to fend off predators, but pupae lack this chemical protection. The beetle's mustard oil bomb is crucial for defense, particularly in larvae that store glucosinolates.
A Brazilian research group uses VideometerLab, a multispectral imaging instrument, to analyze pupae and detect dead or empty insects. The device provides precise data on sample quality, improving the efficiency of biological control.
A new study reveals that bumble bee workers tending to pupae sleep significantly less than other bees, even when the offspring are not their own. This finding suggests that substances produced by the pupae may drive the reduction in sleep.
The team aims to develop a sorting-machine prototype using pupae images and machine-learning algorithms to process tens of thousands of images daily. They also design a robot to sort the pupae based on the result of the algorithm, with the goal of reducing tsetse populations in sub-Saharan Africa.
Researchers found that ants wrap pupae in a silk cocoon to shield them from acidic chemicals used for nest cleaning. This practice protects the pupae from harm, reducing mortality rates. The study provides insights into ant immunopathology and its similarities with human immune responses.
Researchers discovered fossil parasites inside their hosts, describing four extinct wasp species that were unknown until now. The study provides major information on the evolution of parasitism and its impact on ecosystems.
Scientists have discovered a mass emergence of rare mantis-flies in an Australian macadamia orchard, capturing the first-ever images and videos of their larval stage. The larvae feed on unknown prey, prompting further research to uncover their diet.
A Canadian research team, led by a UC Riverside expert, has won the Hult Prize to develop insect-based meals for impoverished regions. Insects are excellent low-cost sources of protein and essential nutrients.
Ant pupae employ acoustics to signal their rightful place in the colony's hierarchy, influencing adult ants' behavior. Researchers discovered that pupae make sounds similar to adults with 'file and scraper' organs, essential for maintaining social status.
Enslaved worker ants kill off parasite offspring to increase chances of survival for their neighbors. Slave workers feed and care for larvae but neglect pupae, resulting in low survival rates. This behavior benefits neighboring colonies by reducing slave-maker colonies' growth and effectiveness.
Male Cardiocondyla obscurior ants use chemical tagging to identify and kill younger rival males, ensuring colony survival. This behavior increases the chances of surviving fights against two-day-old males to 14%.
A parasitoid wasp induces its moth caterpillar host to stop feeding, remain close to the pupae, and defend against predators, resulting in increased pupae survival. The caterpillar's behavioral changes appear to outweigh potential risks of increased transmission for the parasite.
Research suggests that elephants may be 'tipsy' due to marula tree bark containing a beetle pupae, not ethanol from the fruit. A high diet of marula fruit is unlikely to cause intoxication in three-ton elephants.
Threadsnakes have evolved a unique feeding mechanism, devouring pupae and larvae of ants at an incredible rate of three or four bites per second. This rapid-fire eating pattern may be crucial for their survival in ant-infested environments, allowing them to outsmart powerful worker ants and secure food.
A team of Cornell University researchers discovered that beetle pupae can create hundreds of deterrent compounds using combinatorial chemistry. The pupae secrete these complex chemicals through microscopic body hairs, thwarting most predators and ensuring their survival in the field.
