Description
Technical field
The invention belongs to plant protection art, more particularly to a kind of Frankliniella occidentalis decoy containing aggregation pheromone component
Matter and its field use in conjunction technology with colour table.
Background technology
The small insects such as thrips, aleyrodid, red spider, liriomyza bryoniae and aphid every year to the Important Economic crop in China, including
Vegetables, flowers etc. cause serious harm.If Frankliniella occidentalis (Frankliniella occidentalis) is with rasping-sucking mouthparts
Thorn inhales host plant juice, tender leaf of causing harm, blade, floral organ, and delay and is bloomed at lamina, blade and spend lopsided atrophy and discoloration or
Fallen flowers, shedding, young fruit of causing harm cause scar and deformity.It also propagates serious tomato spotted wilf virus (TSWV) of causing harm simultaneously, by
Evil product yield is remarkably decreased or quality variation cannot be sold, and plant cannot grow completely when serious.
At present, the control method on thrips mainly has 3 kinds：Chemical prevention, biological control and physical control (Wu Qingjun
Deng 2005；Zhong Feng etc., 2009).But development duration is shorter, and individual little Yi is hidden, and energy is strong, and right since thrips has
Most of insecticides tested is also easy to produce the features such as resistance, and the effect for causing chemical prevention and physical control is unsatisfactory.It is in view of such
It is extremely urgent to find a kind of nuisanceless sustainable thrips control method for present situation.And it is prevention thrips using insect pheromone
One of effective measures (Hamilton et al., 2005).Insect pheromone arises directly from insect body, as a kind of non-
Chemical Control measure can be not only used for pest population dynamics monitoring, while can also be combined to improve evil with other prevention and control measures
Worm control effect.Aggregation pheromone is one kind of insect pheromone, and some researches show that be prevention thrips using aggregation pheromone
One of effective measures (Kirl and Hamilton, 2004；Hamilton et al., 2005), it is extremely low due to the use of dosage,
And worked in the form of discharging in air, noresidue problem will not bring harm to human health and environment, and resistance is done harm to
The identification of worm or attracting ability will not reduce, therefore be conducive to the improvement of resistant insect, while also in can effectively protect nature
Natural enemy, be conducive to the integrated applications of agricultural pests.
The current correlative study in relation to thrips aggregation pheromone Components identification and bioactivity and Field information is domestic and international
Still it is less.So far, the only aggregation pheromone ingredient of Frankliniella occidentalis and flower thrips (Frankliniella intonsa)
Efficiently separated and identified, the aggregation pheromone main active components of two kinds of thrips be (R)-lavender acetic acid esters (R)-
Lavandulyl acetate) are He Ni meat base (S) -2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate)
(Hamilton et al.,2005；Lv Yaobin, wishes dawn cloud etc., 2012).Although the aggregation pheromone component of Frankliniella occidentalis obtains
The separation such as Britain expert Hamilton identify that still, these experts are also considered as and Ni meat base (S) -2-Methyl Butyric Acid ester simultaneously
(neryl (S) -2-methylbutanoate) some related compounds of molecular structure of compounds, such as isobornyl
valerate、isobornyl 2-methyl butanoate、isobornyl pivalate、lavandulyl valerate
With as aggregation pheromone Zu Fen Ni meat bases (S) -2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate) all to west
Flower thrips has strong attractive activity.These experts have used in test the release device of plastic colorimetric plates+lure, the color of the device
Plate can be used yellow, white and blueness, and lure in dipped Rubber end or glue with attractive activity compound using dissolving in work
The mode of property compound, and provide a field case study on implementation, and applied related patents (United States Patent (USP), No.US 7,
985,412B2, Jul.26,2011).But Hamilton etc. then thinks, component (the R)-lavender found in Frankliniella occidentalis
Acetic acid esters (R)-lavandulylacetate) there is no bioactivity, it is impossible to there is individual attracting action to west flower Ji.
In addition, above-mentioned Britain expert thinks (R)-lavender acetic acid esters ((R)-lavandulyl acetate) in its paper
Yu Ni meat base (S) -2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate) do not show increasing in field trials
Effect acts on, and the evidence provided is：(1) (R)-lavender acetic acid esters ((R)-lavandulyl acetate) Yu Ni meat bases (S)-
2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate) 1:1 ratio uses the Frankliniella occidentalis Shuo Liang Yu Ni meat bases captured
(S) quantity that capture is used alone in -2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate) is essentially identical, does not have
Difference；(2) his indoor measurement (R)-lavender acetic acid esters ((R)-lavandulyl acetate) Yu Ni meat base (S) -2- first
The proportion of both base butyrates (neryl (S) -2-methylbutanoate) is 1:0.8-1:5, he thinks nature situation
Both lower ratio is there are an amplitude range, and there is no this optimal situations of some special ratios；(3) he thinks (R)-lavender
The effect of acetic acid esters ((R)-lavandulyl acetate) is unknown.
In short, existing technology shows (R)-lavender acetic acid esters ((R)-lavandulyl acetate) Dui Ni meat bases
(S) -2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate) does not have synergistic effect, without being used in mixed way.
The content of the invention
But we study surprisingly it has been found that, 2 components in Frankliniella occidentalis aggregation pheromone play an important role, wherein
Ni meat base (S) -2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate) individually has attracting ability, although (R)-smoke
Clothing oxalacetate ((R)-lavandulyl acetate) (Chinese name：(R)-lavender acetic acid esters) do not have individually and lure energy
Power, but when (R)-lavender acetic acid esters ((R)-lavandulyl acetate)) Yu Ni meat bases (S) -2-Methyl Butyric Acid ester
When (neryl (S) -2-methylbutanoate) coexists, (R)-lavender acetic acid esters ((R)-lavandulyl acetate) can
Xian writes the attracting ability of Ti Gao Ni meat bases (S) -2-Methyl Butyric Acid ester (neryl (S) -2-methylbutanoate), has very strong
Synergistic effect.
This compound, which is used with not only to dramatically increase, lures worm amount, in addition, the ratio of the two also seems of crucial importance, when them
