[EX Q]: Paragraph: After nearly disappearing in the United States, the bloodsucking pests have made a comeback in recent years, quickly infesting apartment buildings and stubbornly resisting common insecticides. The city of New York alone spends as much as $40 million a year in bedbug control. A study of bedbug genetics presented on Tuesday at the American Society of Tropical Medicine and Hygiene meeting in Philadelphia now suggests why. A team of entomologists led by Coby Schal and Ed Vargo of North Carolina State University studied the genes of bedbugs infesting three multistory apartment buildings in North Carolina and New Jersey and found very low genetic diversity — meaning most of them were very close relatives. They were so close in fact that the team suspects it may have taken just one or two founder insects to start an entire infestation. “We find that bedbug infestations basically start from a very small number of individuals,” Schal said in a telephone interview. “A single mated female bedbug starts the infestation. She gives rise to offspring and those offspring mate with each other and with their mother,” he said. “This is different from many animals,” he said, mostly because close inbreeding can result in genetic deformities, adding, “In humans, it is taboo.”   But he said there are some animals that can withstand such close inbreeding without experiencing detrimental effects including cockroaches. Schal said this may be a trait of insects that have evolved an association with humans and rely on them to get from place to place. Typically this happens when humans bring infested furniture into their homes, and he warns people to inspect second-hand furniture carefully. “There is a myth out there that bedbugs get transported on people,” Schal said. Unlike ticks, the wingless, reddish-brown insects stay attached to people for a blood meal for just 5 to 10 minutes, he said. “The chances that a person is carrying bedbugs on them is quite low.”   According to the U.S. Centers for Disease Control and Prevention, bedbugs do not carry disease, but their bites can cause severe itching and a whole lot of anxiety. Schal said his findings are not likely to lead to new insecticides for bedbugs, but they do underscore the need to move fast once bedbugs are detected. “If you don’t deal with them early they can spread thorough   a building very quickly,” he said. Claim: All in the family: Inbreeding key to bedbug spread.
[EX A]: Inbreeding may be the secret to the bedbug’s success, U.S. researchers said on Tuesday.

[EX Q]: Paragraph: The bee, once widely found in the upper Midwest and Northeastern United States, was listed after U.S. President Donald Trump’s administration lifted a hold it had placed on a plan for federal protections proposed last fall by the administration of former President Barack Obama. Bumble bees are key pollinators of crops such as blueberries and cranberries, and are almost the only insect pollinator of tomatoes in the United States, according to the U.S. Fish and Wildlife Service. Conservation groups that had called for the new classification welcomed the move. “The listing helps mediate threats for this species and for all of those other animals out on the landscape that are suffering similar setbacks,” Rich Hatfield, senior biologist at the Xerces Society for Invertebrate Conservation, said by phone on Tuesday. The rusty patched bumble bee, or Bombus affinis, is one of 47 varieties of native bumble bees in the United States and Canada, more than a quarter of which face risk of extinction, according to the International Union for the Conservation of Nature. The population and range of the bee, named for the reddish blotch on its abdomen, have declined by more than 90 percent since the late 1990s due to disease, pesticides, climate change and habitat loss, according to wildlife officials. The agency in September proposed safeguarding the bee, but the listing was delayed by Trump’s White House as part of a broader freeze on rules issued by the prior administration. Environmental advocacy group the Natural Resources Defense Council sued last month, arguing that suspending the listing without public notice or comment violated the law. The NRDC said on Tuesday it was evaluating the next steps in its legal fight. Government scientists said the delay, part of a standard review, was not expected to affect the insect’s conservation, Interior Department spokeswoman Heather Swift said in a statement on Tuesday. The agency “will work with stakeholders to ensure collaborative conservation among landowners, farmers, industry, and developers in the areas where the species is native,” she added. Bumble bees pollinate wildflowers and about a third of U.S. crops, according to the Xerces Society. A recent study by the Center for Biological Diversity found that more than 700 of the 4,000 bee species native to North America and Hawaii may be inching toward extinction. Claim: First U.S. bumble bee added to endangered species list.
[EX A]: The rusty patched bumble bee became the first wild bee in the continental United States to gain federal protection on Tuesday when it was added to the government’s list of endangered and threatened species.

[EX Q]: Paragraph: Studies declaring health benefits found in cocoa, combined with new chocolate products touting lower fat and calories, have helped manufacturers to capitalize on a growing consumer appetite for these alternative sweets in the United States, the world’s biggest chocolate consumer. Nestle USA says the lower-calorie chocolate line that it launched in 2011 was one of its snack division’s best-ever debuts. A year later, Hershey Co brought out Simple Pleasures, a brand with almost a third less fat than average milk chocolates. The world leading maker of industrial chocolate for retail brand companies, Barry Callebaut, says products with health benefits now make up 5 percent of its sales. Rising demand for these products is increasingly apparent in a recent improvement in the North American cocoa market, where demand slowed throughout much of 2012. A surprising turnaround was seen in the first quarter when “grindings”, the term for processing cocoa beans which is shorthand for commercial demand, rose nearly 6 percent in North America, the biggest annual jump in nearly two years. In Europe and Asia, first quarter grindings tumbled. Also included in the supposedly better-for-you chocolate segment are bars that are gluten- or sugar-free, or that have additives like probiotics to help promote healthy digestion and other possible benefits. Francisco Redruello, Euromonitor International senior industry analyst for foods in London said these “healthier” products are already having an influence on grindings. “There’s really a concern about obesity in the U.S. and this is having an impact on demand for chocolate confectionery,” he said. “So 2012 has seen new concepts, new lines, trying to launch healthier chocolate with low fat.”  The tonnage of reduced fat chocolates sold in the United States jumped 5 percent in 2012, outperforming the overall chocolate confectionary market, according to Euromonitor, an international consumer market research firm. Euromonitor expects U.S. chocolate confectionery retail volume sales will improve and be flat in 2013, and said volume fell roughly 15 percent over the past five years after many companies reduced treat sizes. The United States is the No. 1 chocolate-consuming country, though several European countries consume more per person. About 13 percent of the world’s annual cocoa production, just over 500,000 tonnes, is used for U.S. chocolate candy, according to U.S. Economic Census data analyzed by the National Confectioners Association (NCA). That accounts for two-thirds of total U.S. cocoa consumption. “Today, it is increasingly about consumers weighing not only the costs of goods, but the multitude of benefits they offer as well,” said Todd Hale, a senior vice president, consumer and shopper insights for Nielsen, which provides global consumer information and insights. Nestle USA, a subsidiary of Nestle SA, expanded on its low-fat Skinny Cow frozen snack line with Skinny Cow Candy in 2011. In March, it added Divine Filled Chocolates to their line: 130-calorie pouches of three chocolate candies. Tricia Bowles, communications manager for Nestle Confections & Snacks, Nestle USA, said this was one of the most successful new product launches in her 20 years with the division. “We do not view these products as being healthy but fantastic alternatives to what you might eat when we all know we love chocolate,” Bowles said. Hershey states that its Simple Pleasures line contains 30 percent less fat than the average leading milk chocolates. Swiss-based Barry Callebaut, which manufactures chocolate for large food companies like Hershey Co, Mondelez, Unilever, as well as bakeries and others, has also noticed the shift, said spokesman Raphael Wermuth. Wermuth said the company sees rising demand for chocolates with “health benefits”, such as chocolates with high flavonol content, which scientists have found to positively impact brain performance. Other chocolates that fall into this category include those with less fat or that are sweetened with refined sugar alternatives such as stevia. Meanwhile, a recent study by global market research provider Mintel showed U.S. consumer preferences shifted away from milk chocolate toward dark chocolate, which is considered to have more health benefits. Milk chocolate is still favored overall, and while Simple Pleasures and Skinny Cow have a small following among the diet conscious, they will remain a tiny niche. “In general, people don’t eat chocolate to feel well, they eat it to feel good,” said Marcia Mogelonsky, director of Innovation and Insight at Mintel. “The last thing on most chocolate eaters’ minds is health.” Claim: 'Healthier' chocolates gives U.S. cocoa demand a shot in the arm.
[EX A]:
In an increasingly diet-conscious nation where the amount of chocolate candy sold has tumbled in recent years, a niche segment of the U.S. market is taking off: so-called “healthier” chocolate.
