Occurrence and Integrated Control Methods of the Eggplant Yellow Spot Borer
Since the 1990s, eggplant has developed rapidly in Jingning County, and the county's planting area has now exceeded 1,300 hectares, with an annual total output of more than 51,000 t. At the same time, the eggplant yellow spot borer has shown an increasing trend of damage in the county, affecting the development of eggplant production. For this reason, the author conducted a preliminary study on the occurrence pattern and integrated control techniques of this pest. 1 Occurrence and damage characteristics The eggplant yellow spot borer, also known as the eggplant borer, belongs to the order Lepidoptera, family Pyralidae. Its larvae bore into and damage eggplant flower buds, stamens, ovaries, tender stems, tender shoots and

Occurrence and Damage Characteristics of Tea Tussock Moth and Integrated Control Methods
In recent years, with the development of pollution-free tea and organic tea production, the frequency and amount of chemical pesticides used in tea gardens have decreased, and some tea gardens even do not use chemical pesticides, resulting in aggravated damage by the tea tussock moth in a short period. In the county where the author works, tea tussock moth damage has occurred for several consecutive years, and after being damaged, the tea plants were left with only bare branches, greatly affecting the economic income of tea farmers. 1. Damage symptoms: The tea tussock moth larvae bite and feed on leaves, causing leaf notches and bare branches. 1st-2nd instar larvae gather on the underside of leaves to feed on the mesophyll, leaving only the epidermis and veins, and the damaged leaves appear transparent

How to prevent and control bee diseases in spring? A detailed explanation of integrated control measures
The occurrence of bee diseases is directly related to beekeeping and management techniques. Once a disease breaks out, it will inevitably affect colony growth and economic returns. Especially in northern China, where the temperature difference between early and late spring is large and nectar and pollen sources are scarce, bee colonies are most prone to bee diseases. Therefore, in spring, the measure of "prevention first, treatment as a supplement" should be used to control the occurrence of bee diseases. Selection and treatment of apiary sites The basic conditions for beekeepers when choosing a site should be shelter from the wind, facing the sun, and dry terrain. In spring, choose low mountain areas or cutover land with many willow species and mainly Aceraceae plants. Only

Key Points of High-Yield Technology for Integrated Fish-Lotus Culture in Ponds
0. Introduction The grid-pond fish-lotus integrated culture technology involves partitioning hardened lotus ponds with roof tiles, hard boards, etc. into small grids of 2-4 sq m each, and planting lotus within the grids. On average, each mu of water surface produces 0.5 wan kg of lotus and 400-450 kg of fish, with a net benefit of over 10,000 yuan per mu. This technology can utilize abandoned pits, wasteland, riverbank land, and scattered marginal land to build grid-pond fish-lotus integrated culture systems. It features small investment, low cost, quick results, and high efficiency, making it suitable for widespread development by rural households. It can both increase economic income and improve market

How to treat swine winter diarrhea? A detailed explanation of integrated Chinese and Western medicine therapy
Porcine epidemic diarrhea in winter, commonly known as winter diarrhea, has its peak incidence from mid-December each year to mid-January of the following year; it strikes suddenly, spreads over a wide area and spreads rapidly; the incidence rate is high, seriously affecting the growth and development of pigs. 1. Symptoms The incubation period of the disease is generally 12-18 h. After infection, adult pigs show symptoms of watery diarrhea; the feces are initially grayish-white, gradually becoming yellowish-green, with an offensive fishy odor. Abdominal distension, vomiting, body temperature rises to 40-41°C in the initial stage, and once the diarrhea passes, the body temperature drops. Thirst and a desire to drink. 10 days

Occurrence and Integrated Control Methods of Gummosis in Goji Berry
Brown lesions appeared on the branches and trunks after 15 d, along with a grayish-white mold layer, while no disease developed from the other inoculated fungi. This result is consistent with the findings of the Ningxia Academy of Agricultural Sciences. Based on the field symptom characteristics and isolation results, it is considered that Clonostachys is the pathogenic fungus causing gummosis, while Alternaria and Fusarium are saprophytic fungi of secondary infection. 3 Disease occurrence patterns 3.1 Overwintering of the pathogen and transmission routes In November, diseased goji branches and trunks with lesions were placed on the field surface and in soil at 20 m-30 cm underground respectively, then retrieved in April of the following year for isolation and culture.

How to Treat Stunted Pigs: An Introduction to Integrated Traditional Chinese and Western Medicine Therapy
Stunted pigs are underdeveloped piglets with stunted growth, also called "little old pigs", "runts", or "hedgehog pigs". These pigs only eat feed without gaining meat, causing great waste of manpower, feed, and pen space in pig production as well as economic losses. 1. Symptoms: Stunted pigs have rough, disordered hair, are thin and small in build, with arched backs and sagging bellies, large heads and thick tails; some are anemic, eat normally but grow slowly, and some have alternating constipation and diarrhea; scabies or internal and external parasites are often present. 2. Causes

How to Distinguish Swine Dysentery from Diarrhea? A Detailed Guide to Integrated Prevention and Control Methods
Dysentery and diarrhea in pigs are relatively common, especially in large-scale pig farms. On some pig farms, the harm caused by swine dysentery and diarrhea is quite serious, particularly piglet dysentery and diarrhea, which have become key factors restricting piglet survival rates. Improving the ability to clinically distinguish swine dysentery from diarrhea is of great significance for grassroots animal disease prevention and control workers and large-scale farm (household) owners to promptly adopt prevention and control measures. 1 Differences and Classification of Dysentery and Diarrhea. Dysentery and diarrhea are both clinical symptoms. What is commonly called loose stool mostly

Detailed Explanation of Integrated Prevention and Control Techniques for Common Pig Diseases
The integrated prevention and control techniques for common pig diseases target major epidemic diseases that plague the development of the pig farming industry in the Beijing suburbs, such as porcine foot-and-mouth disease, swine fever, porcine parvovirus, swine enzootic pneumonia, and swine Escherichia coli. Practical and feasible integrated prevention (treatment) techniques have been researched and formulated. The core techniques are: integrated epidemic prevention techniques for large-scale pig farms; immunization and antibody monitoring techniques for important pig farm epidemic diseases; rational drug use for pigs and disinfection techniques for the pig farm environment and the interior and exterior of pigs. Over the years, promotion and application in more than 2,000 large-scale pig farms in the Beijing suburbs have achieved good results, reducing pig death and culling
