An 18×14 mesh has become standard; 16×16 was formerly common and other common sizes are 18×18 and 20×20. For comparison, a typical screen in a clothes dryer has a nylon 23x23 mesh screen. Fiberglass solar screens provide over 75% of UV protection, by using thicker strands and a closer mesh than regular 18x14 fiberglass window screening.
Bird nets are used to prevent bird damage of vegetable and fruit crops as well as seedlings. [1] Frugivore birds and bats can cause great damages to farmers as they tend to peck one fruit, then go to another, therefore ruining a large percentage of otherwise commercially valuable production. Once even a small portion is bitten off, that fruit ...
Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents. [1] [2]For protection against ticks and mosquito bites, the U.S. Centers for Disease Control (CDC) recommends DEET, icaridin (picaridin, KBR 3023), oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), IR3535 and 2-undecanone with the caveat that higher percentages of the active ingredient ...
The American cockroach genome is the second-largest insect genome on record, after Locusta migratoria. Around 60% of its genome is composed of repeat elements. Around 90% of the genome can be found in other members of Blattodea. The genome codes for a large number of chemoreceptor families, including 522 taste receptors and 154 olfactory ...
A 2013 Missouri survey showed that multiply-resistant weeds had spread. 43% of the sampled weed populations were resistant to two different herbicides, 6% to three and 0.5% to four. In Iowa a survey revealed dual resistance in 89% of waterhemp populations, 25% resistant to three and 10% resistant to five. [7] Resistance increases pesticide costs.
