second discovery could be game changer in fight to control kudzu bugs

7a replica bags wholesale AUBURN UNIVERSITY Within a few days of discovering a native parasitic fly that may reduce kudzu bug numbers significantly over time, Alabama Cooperative Extension System specialist and wholesale replica designer handbags Auburn University researcher Xing Ping Hu has discovered a local egg parasitic wasp. 7a replica bags wholesale

buy replica bags The finding the first discovery of a local wasp that parasitizes eggs of the exotic kudzu bug could prove to Wholesale Replica Bags be a game changer in the fight against this invasive Replica Bags species, Hu said. Along with the earlier finding of a fly purse replica handbags that preys on kudzu bug adults, Hu replica handbags online said the discovery Designer Fake Bags of the parasitic egg wasp doubles the frontline of defense using natural enemies to fight this pest. buy replica bags

Golec noticed black masses within kudzu bug eggs something Designer Replica Bags that immediately caught his attention because the Replica Handbags translucent eggs normally are characterized by a pinkish or yellowish tint. Even more intriguing, the black masses appeared replica handbags china to be moving. He suspected that he had discovered evidence of a local predatory wasp that finds kudzu bugs suitable repositories for its own eggs a hunch confirmed through follow up investigation. replica bags china

cheap designer bags replica a high speed camera, the wasps were recorded and observed under high quality replica handbags a microscope as they emerged from these parasitized kudzu bug cheap replica handbags eggs, Hu said. male wasps emerged first, guarding the parasitized eggs until the females came out. female wasps emerge sexually mature. As aaa replica designer handbags soon as the wasps emerge from the eggs, they mate and the females immediately begin laying eggs, repeating the cycle. The rates of parasitized eggs turned out to be especially high. cheap designer bags replica

replica bags Hu said KnockOff Handbags kudzu bugs are no different than any other insect species introduced into a new area. Figuratively speaking, entering an area with no known indigenous predators is like drawing a lucky lotto number: The species thrives and its numbers mushroom as it develops into a Fake Designer Bags full blown invasive species, often wreaking havoc within its new environment. replica bags

replica designer bags wholesale why they become invasive in the first place, Hu said. have no natural enemies to balance the ecosystem. It as if they saying, one can mess with me so I can do what I want.’ the other hand, an incoming species is unlucky if it enters an environment teeming with natural Fake Handbags enemies. In such cases, the species numbers may spike for a few years until local predators respond to the new species. replica designer bags wholesale

replica designer backpacks typically is a long, labor intensive and expensive process that requires laboratory replica bags studies to ensure that this predator is not only capable of surviving in its new environment but also that it preys only on the targeted invasive species and doesn attack native replica Purse species, Hu said. if the species overcomes these laboratory hurdles and is introduced, it often an open question whether it can Replica Bags Wholesale survive in sufficient numbers to make a difference. is why Hu is excited about the discovery of the local predatory wasp species. Its discovery, along with that of the fly species, may help provide less expensive methods for reducing kudzu Replica Designer Handbags bug numbers. replica designer backpacks

high quality replica bags Aside from confirming that there is yet another local predator of kudzu bugs, Hu said the wasps exhibit higher levels of parasitism than the recently Handbags Replica discovered flies. Egg parasites typically are more effective predators than species that prey only on adults, she said. high quality replica bags
