ASIAN BUG: COMBAT IT
WITH THE ZEOLITE CHABASITE
Asian Bug is identified as Halyomrpha halys and comes from China, Japan and Korea. In 2007 it was seen for the first time in Europe, in 2010 in America and in 2012 in Italy.
The Asian Bedbug in Italy is present in Emilia Romagna, Lombardy, Piedmont,
South Tyrol and is rapidly expanding in other geographical areas of central and northern Italy. In the absence of containment measures, the Asian Bug will soon arrive also in the South of Italy. It is very proliferating, it multiplies quickly and also ravenous, given the absence of natural predators in our country. In my experiments I obtained important results against this bug using:
a mixture of micronized chabasite zeolite and kaolin, neem oil, bitter quassia and chili pepper diluted in water.
The treatment should be performed once every 15 days (the mixture with chaolite and high-dose kaolite), because it creates problems to the adherence of the bug on the leaves, in the movements, in breathing and in reproduction. The neem, the bitter quassia and the chili are excellent repellents. In my studies it seems that these substances interfere on the system of receiving the bug towards the plant tissues (they manage to hide the odors useful for locating the points to attack). In my two experiments that I carried out in Emilia Romagna and in Trentino using the mixture indicated above I managed to reduce by 54% the attacks of the bug on vines, vegetables and apple trees. I am carrying out new experiments to evaluate new extracts (viscose and leptospermum scoparium) and new dosages of zeolite + kaolin.
The adults are about 1.7 centimeters long and have the characteristic common shield shape also in other bedbugs. There are various shades of brown on the top and on the underside, with shades of gray, off-white, black, copper and bluish spots. Other recognition characters of this species include alternating light bands on the antennas and alternating dark bands on the outer edge of the abdomen. The legs are brown with faint white patches or stripes. The outlet of the odoriferous glands is located on the underside of the thorax, between the first and second pair of legs, and on the dorsal surface of the abdomen. In the places of origin (Japan, China, the Korean Peninsula and Taiwan) there is only one generation per year, while in the most favorable areas up to four. The females mate several times in a row and the pairing lasts about 10 minutes (much less than similar species). Between 100 and 500 eggs are deposited, with an average of around 250 eggs. The development time of adult animals depends on temperature and diet (in laboratory conditions it lasts about 50 days).
