production of Trichogramma
TUU 062 - 00717867 - 002: 2009
The primary means of biological control of pests.
Trichogramma insect - entomophage that kills nearly 160 - year - pest species in the egg stage.
Trichogramma effective against pests that are hidden way of life, because the chemicals are ineffective against them. It is produced in biological laboratories on the eggs of natural kinds of insects, mainly on the number of eggs of the grain moth. Trichogramma is developing in the midst of her eggs infected insects. A parasitic way of life are only the larvae and adults feed on nectar.
In Ukraine more than 10 known species Trichogramma, 5 of which mass is diluted in biolaboratories: (a pint), (avanestses) (semblidis) (dendrolimi), T. sasoeaae (katsetsiya).
Recommended: for sewn with / g and crops from noctuid leafeating scoop ognevok, whiteflies, moths, leaf rollers, corn (stalk) and beet webworm, plodozhorok, white moth, cotton bollworm, and other.
Release of Trichogramma produced on areas sown with winter crops, on maize, sunflower, sugar and fodder beet, perennial herbs, fruit crops, potatoes and other vegetables.
Trichogramma used in these periods:
First, during lay leafeating and noctuid species scoop on crops of sugar beet, perennial grass, pea, millet, vegetable crops approximately II - III early May - 1 decade of June;
Second, against the European corn borer, cotton and other leaf - eating scoop on maize, sunflower, hemp, millet with about 2 decade of June - July 3, ten days depending on the region;
Third, against the second (third) generation leafeating and noctuid scoop on the area under the crop of winter crops, approximately begin with II August.
Against each generation of the pest spend two or three issues with the interval of 5 - 7 days, and in case of release of different ages (diapaziruyuschey) Trichogramma - 1 - 2 release after 10 - 12 days. The beginning of release of Trichogramma is carried out in the beginning of oviposition, subsequent to the period of mass lay pest.
Conditions of application of the rule:
The optimum conditions for the development of Trichogramma: 18 - 26 C Temperature of heat, relative humidity (70 ± 10)% .
Revival of Trichogramma produced manually or diseased grain moth eggs for 12 - 24 hours prior to the revival of adults.
In adults Trichogramma phase discharged from 7 to 11 o'clock in the morning or evening, 16 to 20 manually. Per hectare its v'50 feature points using paper lumps,
Not revived Trichogramma (Trichogramma the affected grain moth eggs) can be produced at any time of the day by air way.
Mechanized produce jet entering through AN - 2, motodeltoplanami small aircraft or aircraft type "Cessna" from special equipment.
On average, single application rate of Trichogramma is 50 - 100 thousand individuals per hectare.
Trichogramma belongs to the family Trihogramatid (Trichogrammatidac) number of Hymenoptera that parasitize on the eggs of many pests - winter, cabbage, oklichnoy, cotton, pea, vegetable garden and a number of noctuid and leaf - scoop, corn, meadow and American butterflies Belanov, plodozhorok, leaf rollers , beetles, sunflower moth, various kinds of moths and other insects - more than 160 species of herbivores.
In Moldova to combat agricultural pests the most widespread application acquired form brown (evanestsens) Trichogramma.
Body length 0. 4 - 0. 9 mm. Trichogramma developed in the middle of it infected eggs of harmful insects. Parasitic way of life are only the larvae and adult insects in nature feed on the nectar of flowers with dew. Trichogramma eggs infected within a few days become a characteristic black color, with a bluish tinge. The parasite (Trichogramma) turns into a pupa in mid zhivitelya eggs. Reformed from pupae adults they form through holes in the egg shell extend outwardly. Characteristically, the females spawn mature. Mating Ttrihogrammy passes immediately after it emerges from the egg zhivitelya. Then oviphages again begins to infect eggs zhivitelya.
On the first day of life, the female lays the greatest number of eggs. Lifespan adult was dependent on temperature and humidity: decreases with increasing temperature and decrease in humidity. Development Trichogramma lasts on average from 8 to 50 days.
The lower threshold of development is + 10 0 C. In the conditions of Moldova is developing to nine generations of the parasite. However Trichogramma development cycle does not coincide with the cycle of its major zhiviteley, so a large part of Trichogramma wintered in April, he finds pest eggs, and egg - laying age which occurs later. The priority is to replenish the amount of biological laboratory Trichogramma - settling on agricultural crops. Release of Trichogramma is carried out in two or three steps:
- at the beginning of the laying of pests;
- with the onset of mass lay.
Terms specifically defined application in each zone Moldovan experts forecast items and farms.
Biolaboratoriya provide methodological and practical assistance on making Trichogramma (aviavneseniyu).
Estimated timing and application rates of Trichogramma against major pests:
· Against winter and other noctuid scoop:
I - generation pest - III of decade of May - I of decade of June (200 - 300 tys. osobin / ha)
II - generation pest - II - III August decade (200 - 300 tys. osobin / ha).
· Against corn borer:
III decade of June - II decade of July (300 tys. osobin / ha. )
· Against cotton bollworm
II decade of July - II decade of August (300 tys. osobin / ha. )
· Against the sunflower moth
III decade of June - I decade of July (200 - 300 tys. osobin / ha. )
Biolaboratoriya produces Trichogramma different periods of revival, namely:
I term (usually) on 1 - 2 day (after application)
II period (diapaziruyuschaya) 5 - 6 hours - // - // - //
III period (diapaziruyuschaya) 7 - 9 hours - // - // - //
Applications Trichogramma together three terms revival keeps safe the crops throughout the laying period pests. This allows professionals to agricultural enterprises choose avia veneseniya multiplicity and back to normal.
Soroca Production biolaboratoriya is able to offer services to aviation and to provide methodological assistance on entering.
