The New york times reported insects appearing early and increased pollen allergies in some states. The state of Michigan sustained $500 million in fruit crop damage after an April frost destroyed the early flowerings of trees according to the U s. Geological Survey.
So an earlier blooming season for plants may not necessarily mean an earlier end to hibernation to pollinators.

Some nurse their queen and her eggs while others fly out in search of pollen and nectar.
Swarming Effect When a queen gets old she flees the hive with a swarm of mostly nurse bees leaving the colony and its larvae to her successor.
Queen When a colony's queen grows old or infirm nurse bees secrete a royal jelly high in fatty acids and protein and feed it to a few larvae.
and produces a new queen who will spend her days laying thousands of genetically similar eggs.
Nurse Most female bees begin their lives as nurses who care for the queen and larvae.
They clean wax cells for the queen's eggs and feed the larvae honey and pollen.

And engineers have developed the first flying insect-inspired vehicles opening the door to an entirely new class of machine:
Although insects and their relatives represent roughly 80 percent of the world s animal species ome 900000 known types he mechanics of their flight had long been an enigma.
But as the wings of insects flap back and forth the air around them is constantly changing.
And the stubby wings of bees and other insects lift far more weight than can be explained using conventional steady-state aerodynamics principles.
Engineers have developed the first insect-inspired vehicles opening the door to an entirely new class of machine:
In the 1970s Torkel Weis-Fogh a Danish zoologist at the University of Cambridge used high-speed photography to analyze the exact wing motions of hovering insects and compare them to the insects morphological features.
From this he formulated a general theory of insect flight which included what he called the clap-and-fling effect.
When insect wings clap together and then peel apart between the up and down strokes the motion flings air away
This vortex creates the force necessary to lift the insect between wing flaps. Similar vortices might be generated by the angle

What remained was to put it all together into a working insect-size flying machine. On a freezing day in 2006 Wood arrived at his Oxford street laboratory at Harvard.
and demonstrating for the first time stable hovering and controlled flight maneuvers in an insect-scale vehicle. I didn t end up sleeping the rest of that night Wood says.

#Significant advance reported with genetically modified poplar treesforest geneticists at Oregon State university have created genetically modified poplar trees that grow faster have resistance to insect pests
With this genetic modification the trees were able to produce an insecticidal protein that helped protect against insect attack.
Insect attack not only can kill a tree it can make the trees more vulnerable to other health problems said Amy Klocko an OSU faculty research associate.
In a really bad year of insect attack you can lose an entire plantation. Hybrid poplar trees which are grown usually in dense rows on flat land almost like a food crop are especially vulnerable to insect epidemics the researchers said.
Manual application of pesticides is expensive and targets a wide range of insects rather than only the insects that are attacking the trees.
A number of the GMO trees in this study also had improved significantly growth characteristics the researchers found.
Annual crops such as cotton and corn already are grown routinely as GMO products with insect resistance genes.
and are subjected to multiple generations of insect pest attacks. That's why engineered insect protection may offer even greater commercial value
and why extended tests were necessary to demonstrate that the resistance genes would still be expressed more than a decade after planting.

and other insect species--and the future of many of those species is uncertain. Now researchers from North carolina State university are proposing a set of guidelines for assessing the performance of pollinator species
in order to determine which species are most important and should be prioritized for protection. Widespread concerns over the fate of honey bees and other pollinators have led to increased efforts to understand which species are the most effective pollinators
since this has huge ramifications for the agriculture industry says Dr. Hannah Burrack an associate professor of entomology at NC State

It was hoped that these insects would take over these important services when they were introduced first into central Chile in southern South america in 1998 as pollinators in a few greenhouses with the backing and approval of the state authorities.
But in the greenhouse they did not stay. Some individuals escaped and very soon they established colonies in the wild.
But that was not All the buff-tailed bumblebee turned out to be an extremely invasive insect that embarked on an unparalleled victory tour that took it as far as Patagonia.
The couple collected these insects during several trips to southern South america in order to document their rapid spread do genetic analyses
By 2012 the insect had penetrated already deep into south Patagonia reaching the gateways to some of the major national parks. Given that colonies
and not individual insects have to become established this migration speed is astonishingly fast says Paul Schmid-Hempel.
As however there are often strong winds in Patagonia in the summer Schmid-Hempel believes that it is possible that the insects could be transported easily to many locations.
#New rearing method may help control western bean cutwormthe western bean cutworm is a destructive insect pest of dry beans and corn.

We examined dietary data to quantify how much different primate species feed on fruit leaves and insects--particularly in relation to their body size.
Meanwhile smaller primates which have high metabolic requirements eat more insects as they provide a high-quality source of nutrients and calories.
The wasp belongs to the Hymenoptera superfamily known as Chalcidoidea which parasitize other insects spiders and some plants.
The new findings demonstrate the value of studying insect fossils Heads said. The fossil record of insects is very extensive both geographically and temporally.
It goes back 415 to 420 million years and preserves the ancestral forms of a lot of the insects that are alive today he said.
So it's a great resource for understanding insect evolutionary history and the distribution of insects across the planet in the past.
The presence of a wasp with an ovipositor that looks like those used by fig wasps today is not hard evidence that figs were around in the fossil wasp's day--a time of dinosaurs Heads said.

For egg-laying insects selecting the best site to lay eggs is crucial for the survival of the eggs and larvae.
First Marcus Stensmyr Bill Hansson and their colleagues in the Department of Evolutionary Neuroethology tested the preferred egg-laying substrates of fruit flies by letting insects select among different ripe fruits.
These research results provide important information about the criteria that insects use to select an oviposition site that guarantees the improved development of their offspring.
Marcus Stensmyr is convinced that#oethere are similar processes in other insects and ways to manipulate them#These insights may lead to new ways to control insects especially those that destroy crops or transfer diseases.

#Himalayan flowers shed light on climate changeflower color in some parts of the world including The himalayas has evolved to attract bees as pollinators research has shown for the first time.
Associate professor Adrian Dyer of Monash and RMIT said previous studies had shown that flower color evolved to attract bees as pollinators in temperate environments
Mountainous environments provide an ideal natural experiment to understand the potential effects of changing climatic conditions on plant-pollinator interactions
since many pollinators show preferences for localised conditions and major pollinators like honeybees do not tend to forage at high altitudes Associate professor Dyer said.
Dr Mani Shrestha from Monash University and his colleague Prakash Bhattrai from the Tribhuvan University Kathmandu collected spectral data from more than 100 flowering plants in Nepal over a range of altitudes from 900
Using computer models to examine flower colors as bees would see them the team addressed how pollinator vision had shaped flower evolution.
and alpine (3000-4100m) regions showed evidence of having evolved color spectral signatures to enhance discrimination by bee pollinators.
The finding was a surprise as flies are thought to be the main pollinator in many mountain regions
and these insects have been such effective pollinators that they have led to the evolution of distinctive bee-friendly colors Dr Shrestha said.
The research could shed light on how flower colors may continue to evolve in particular environments depending upon the availability of the most effective pollinators.
The timber of many of the 198 species is of great economic interest because of its excellent insect and fungus resistance.

The latest weapon in combatting climate changeas U n. climate talks continue in Warsaw soon a flying insect-like robot developed by scientists at Wake Forest University will give an unprecedented look at Peru's tropical cloud
The mountain pine beetle is the most damaging forest insect in North america and climate change has allowed the current epidemic to spread from lodgepole pine to jack pine a tree species that was thought to be unsuitable for beetle survival in Alberta.
The chemical compounds play a key role in the insect's ability to find a mate and to overcome tree defences.
Understanding the role of pheromones in beetle invasion also allows for quicker monitoring of the insect's activities in jack pine forests Erbilgin said.
and small-to medium-size insect herbivores that--by causing tree damage and death--disrupt the ecosystem services provided by trees.
We usually think of animals'chemical signals (called pheromones) as communication systems that convey only very simple sorts of information said Christina Grozinger professor of entomology and director of the Center for Pollinator Research Penn State.
However this study demonstrates that queen honey bees are conveying a lot of nuanced information through their pheromones.
We have found that the information queens are conveying constitutes an honest message about their reproductive status and quality.
The queens are'telling'the workers that they are queens whether or not they are mated
if their queen is mated well? According to Elina Niã o postdoctoral fellow Penn State previous research has shown that colonies headed by more promiscuous queens--those who mate with many males--are more genetically diverse and therefore healthier more productive and less likely to collapse.
Beekeepers have been worried very about their queens since they seem to not be lasting as long--a few weeks
or months instead of one or two years said Niã o. We know that workers will replace their queens
when they are not performing well. So if worker bees are able to detect poorly mated queens
and take steps to remove them that could be an explanation for the rapid rates of queen loss
and turnover that beekeepers have been reporting. The researchers who represent Penn State North carolina State university and Tel aviv University describe how they assigned queen bees to a variety of treatment groups.
In one group they inseminated queens with a small volume of semen to mimic a poorly mated queen scenario.
In a second group the researchers inseminated queens with a large volume of semen to mimic a well-mated queen scenario.
In a third and fourth group they inseminated queens with low and high volumes of saline.
The researchers then dissected the queens removing two glands that are known to produce pheromones--the mandibular gland and the Dufour's gland.
The team found that worker bees preferred pheromone extracts of queens that were inseminated with semen rather than saline.
They also found that queens inseminated with higher volumes of semen or saline as opposed to those that were inseminated with low volumes of semen
These results suggest that queens are signaling detailed and honest information about their mating state and reproductive quality to workers
When workers replace failing queens it is particularly damaging to beekeepers since it can take up to three weeks for the new queen to begin laying eggs
and another three weeks for the new workers to emerge as adults. This reduces the workforce
The Dufour's gland seems to inform workers that queens have mated while the mandibular gland seems to indicate the queen's mating quality Niã o said.
This also means that these glands are likely being regulated via different neurophysiological pathways. According to Grozinger in addition to signaling queen bee reproductive status and quality queen bee pheromones regulate how fast workers mature and transition from taking care of developing larvae to foraging outside the hive.
and poor nutrition on queen pheromone quality to see if the queen also is providing workers with information about her health.
The more we know about what affects the queen's health the better chance we will have of creating high-quality queens
and disease-resistant stocks of honey bees Niã o said. Story Source: The above story is provided based on materials by Penn State.

When ants patrolling the surface of the tree encounter a leaf-eating insect they bite the insect until it falls from the tree Pringle said.
but potentially lethal insect attacks may drive the evolution of tree-ant mutualistic strategies under different precipitation regimes.
As the climate changes the increased frequency of extreme weather events such as drought may act together with rare biological events such as outbreaks of insect pests to profoundly alter the ecology and evolution of plant-animal interactions.
