...Israel last week. One of the first objectives for Lady Bird and daughters Lynda Robb and Luci Nugent required a two-mile hike over dirt paths through Independence Forest on the outskirts of Jerusalem. Their destination: a wooded area dedicated to Lyndon Baines Johnson, where Lady Bird planted a pine sapling and Luci watered it. The former First Lady also met with Israeli President Ephraim Katzir and dropped in at the Hebrew University Library. Being a good guest, Lady Bird observed: "There are more books in Jerusalem on my husband than in Washington...
...three presidential candidates took a private rest down home with just a few hundred intimate friends and reporters. Jimmy Carter invited more than 100 kinsmen, journalists and neighbors to a back-country fish fry at his mother's Scandinavian-modern house in the dark slash-pine woods near his peanut fields in sweltering Plains, Ga. The homey cookout was called partly to ease an ecological imbalance in the family pond. As often happens in politics and ponds, the larger fish were gobbling up the smaller fry, making the fishing hole unhealthy...
...fiery sting and driving farm workers from the fields. Some experts believe that it will continue to press forward, adapting to cooler temperatures and inexorably moving toward both the North and the West. In forest areas, the gypsy moth, the tussock moth, the spruce budworm and the southern pine beetle are wreaking devastation on huge areas of woodland, defoliating and killing millions of valuable trees and destroying in 1975 alone enough board feet of timber to build 910,000 houses...
...same species for miles around. Other pheromones identify members of a colony, trigger fight or flight reactions, or are used to mark a path toward food sources. At Beltsville, Jacobson has identified the sex pheromones of the American cockroach. Oriental fruit fly, Mediterranean fruit fly and southwestern pine tip moth. Synthetic forms of such chemicals could, if spread in large quantities over an insect-infested field, so confuse male insects that they might never find females and mate with them...
...other work, scientists at the Boyce Thompson Institute for Plant Research isolated frontalin, a pheromone released by the female western pine beetle to attract other beetles when it finds a tree suitable for feeding and nesting. They also isolated verbenome, a pheromone given off by the males to stop the influx of beetles to the tree after the proper balance of males and females is achieved. After synthesizing both pheromones, the researchers applied both of them to several trees. Approaching beetles were so confused that they lost their nesting and mating instincts and dispersed into the forest. Capitalizing...
