Reagent for inhibiting eclosion of screwworm and application of reagent
CN108077333
The invention relates to the technical field of plant control and discloses a reagent for inhibiting eclosion of screwworm and an application of the reagent. The reagent is prepared from
musa basjoo seed powder and gibberellin
and the balance of water. The musa basjoo seed powder and gibberellin are selected as effective components of the control reagent, and the eclosion number of the screwworm can be obviously reduced by spraying control on the screwworm. In response to the current lack of technology to inhibit fly larvae emergence, especially the lack of plant-based control technology, this invention achieves the inhibition of fly larvae emergence by combining banana seed powder and gibberellin.
Preferably, the
banana seed powder has a weight percentage concentration of 0.4-5%; and the gibberellin has a weight percentage concentration of 0.9-1%.
Step 1: Dilute the reagent described in this invention with water and spray it on the place where prevention and control are needed, or spray it directly into the water for use. Then, after an interval of 48 hours, spray again... After the reagent described in Step 1 is sprayed again in Step 2, repeat Step 1 once after an interval of 72 hours.
The reagent is diluted with water at a volume ratio of water:reagent = 100:15.
Similarly, when spraying directly into water, the amount of reagent used should be determined based on the volume ratio of the water used and the dilution ratio described above.
As can be clearly seen from Table 1, although the use of banana seed powder solution or gibberellin solution alone can inhibit the increase in the number of fly larvae to a certain extent, the degree is limited, and the emergence rate of fly larvae is still above 70%. However, when the reagent of this invention is used for control, the emergence rate of fly larvae decreases significantly, all dropping to below 40%, which is about half of the control group. This shows the synergistic effect of the two.

Traditional Chinese medicine composition for treatment of enteritis of soft shelled turtles and preparation method
CN104523938
The invention discloses a traditional Chinese medicine composition for treatment of enteritis of soft shelled turtles and a preparation method, and relates to the technical field of aquaculture. The traditional Chinese medicine composition is composed of the following materials in parts by weight:
6 parts of radix paeoniae alba, 8 parts of semen raphani, 9 parts of codonopsis pilosula, 3 parts of duchesnea indica, 5 parts of euphorbia humifusa, 5 parts of large angiopteris, 5 parts of screwworm, 6 parts of manyprickle acanthopanax roots, 6 parts of honey-fried licorice roots, 6 parts of plantain herbs, 8 parts of rhubarb, 6 parts of cortex phellodendri, 7 parts of radix scutellariae, 500 parts of water, and 1000 parts of a feed.
The application method of the traditional Chinese medicine composition disclosed by the invention is simple, and is just implemented by putting powder on a soft shelled turtle food table, therefore, the application method is simple; raw materials are easily purchased, and easy to process; the traditional Chinese medicine composition has a good treatment effect on enteritis of soft shelled turtles; the traditional Chinese medicine composition after being taken by soft shelled turtles has no toxic or side effect; the traditional Chinese medicine composition does not affect the growth environment of soft shelled turtles in water; and the traditional Chinese medicine composition can be stored for a long time, therefore, the traditional Chinese medicine composition is easy to keep.
Fly maggot killing preparation based on wild plant euphorbia lunulata
CN102870825
The invention relates to a fly maggot killing preparation based on wild plant euphorbia lunulata and belongs to biological pesticides. The fly maggot killing preparation is specially used for killing fly larvae at places for plenty of fly maggots to breed such as a country open toilet, an urban trash can, a rubbish trash can, a rubbish transfer station, a slaughterhouse leftover treating pond and an urban domestic sewage treatment station and the like. The fly maggot killing preparation mainly solves the problems that known pesticides for killing the fly maggots are chemosynthetic and have high residual, teratogenicity and pollution. The fly maggot killing preparation comprises, by weight,
1-25 parts of euphorbia lunulata extract, 0.05-2 parts of phenyl salicylate, 0.05-5 parts of surfactant and 50-97 parts of 70% ethanol
which are made into preparation solution. Main raw materials of the fly maggot killing preparation are natural plant extracts, and the fly maggot killing preparation is an efficient, non-toxic, green and environment-friendly pest killing preparation and does not cause any poison, pollution or residual to the human body and the environment.
Parasiticide formulation
CN102210319 // AU2011201431 // MX2011003451
A parasiticidal formulation belonging to the field of veterinary medicines, effective against myiasis, flystrike, arising from infestation by larvae of dipterous insects, such as the Coduliomyia spp fly, the New World screwworm fly, in herds of cattle, horses, pigs, goats and other herds; the said formulation comprised by the association of
Pyrethroids such as Cyhalothrin or Lambda Cyhalothrin for residual action against larvae and Carbamates such as Propoxur for immediate action against larvae.

Smear for screwworm control -- US2504207
Example I
A solution is first made up by dissolving
diphenylamine and cetyl alcohol in benzene,
These are present at the following rates based upon the total weight of finished composition.
Diphenylamine H Benzene ------- Cetyl alcohol -_ A separate water-phase batch is then made up by dissolving sodium lauryl sulfate and borax in water, and bentonite is dispersed in this water phase. These ingredients are used in the following amounts by weight based again upon the weight of the total composition.
Per cent ---- --- ------------------------- 0.75 Per cent Water ---------------------- ---------- 33.725 Sodium lauryl sulfate ------------- 0.375 Borax ------------- --------------- --- 0.15 Bentonite ----------------------------- 5.0 The water solution of sodium lauryl sulfate and borax with bentonite dispersed therein is then agitated while the solution of diphenylamine and cetyl alcohol in benzene is added thereto. A smear in the form of an emulsion is obtained.
This smear was applied to livestock and excellent results were obtained in the control of screwworm.
The borax puts the composition a little on the alkaline side and it is Preferred to use a little borax or another mild alkali for this purpose.
In mixing the organic solution and the water phase as above to prepare the emulsion type smear 2,504,207 vigorous agitation should be used in order to obtain a dispersion of minute droplets of the organic phase in the aqueous continuous phase and such a physical state is suitably assured by passing the mixture thru a colloid mill or homogenizer.
