Scale insect

Mealworm beetle T. molitor (Coleoptera: Tenebrionidae) (Linnaeus, 1758) is one of the most important cosmopolitan primary storage pests, scavenging on a variety of post-harvest grains and affecting the quality and safety of food and feed. In addition to being an important factor in feed hygiene, the insect can also be an epidemiological factor of canthariasis.

Simple sequence repeats (SSR), also called microsatellites, have been widely used as genetic markers, and have been extensively studied in some model insects. At present, the genomes of more than 100 insect species are available. However, the features of SSRs in most insect genomes remain largely unknown.

Mitochondrial genome (mt-genome) data can potentially return artefactual relationships in the higher-level phylogenetic inference of insects due to the biases of accelerated substitution rates and compositional heterogeneity. Previous studies based on mt-genome data alone showed a paraphyly of Cimicomorpha (Insecta, Hemiptera) due to the positions of the families Tingidae and Reduviidae rather than the monophyly that was supported based on morphological characters, morphological and molecular combined data and large scale molecular datasets.

Tansy plants (Tanacetum vulgare L.) are known for their high intraspecific chemical variation, especially of volatile organic compounds (VOC) from the terpenoid compound group. Tansy chemotypes have been shown to influence plant-aphid interactions, however, to date no information is available on the response of different tansy chemotypes to simultaneous herbivory by more than one insect species.

Evaluation of newer acaricide Tafethion against San Jose scale Quadraspidiotus perniciosus Comstock and European red mite Panonychus ulmi Koch was evaluated for bio efficacy, phytotoxicity and effect on natural enemies in apple orchards at two locations in Kashmir during the year 2014 and 2015.

Field evaluation of MAK all season Horticultural Mineral Oil (HMO) was done against San Jose scale Quadraspidiotus perniciosus Comstock and European red mite Panonychus ulmi Koch in apple orchards at two locations in Kashmir under field conditions during year 2014-2015. Phytotoxicity and effect on natural enemies were also recorded. HP (HMO) was used as standard check for conducting the experiment. Both the oils were sprayed during dormant and summer season to suppress different stages of the insect pests. Different concentrations of oil were sprayed viz., 2.5, 2.0 and 1.

In order to increase agricultural production different type of pesticides viz., organochlorines, carbamates etc. are used on large scale to kill unwanted insects, pests, plants etc.; as mode of action of most of them is not specific, they often harm or kill organisms other than pests, including humans. Residues of most common pesticides could affect the ultimate consumers (animal and human) especially when pesticide treated fruit/vegetables are consumed raw. Proper processing technique in daily use of vegetables and fruits i.e. washing, peeling boiling, cooking, frying, sun drying etc.

Insecticidal δ-endotoxins of Bacillus thuringiensis have acquired great significance in recent years because of their specificity to target insects and toxicity at very low concentrations. Genes from B. thuringiensis have been the most successful group of genes identified for use in genetic transformation of crops for pest control on a commercial scale. Successes of plant transformation include most of major economic and vegetable crops. Polymerase chain reaction (PCR) is commonly used technique for the presence of transgene in the putative transformants by DNA amplification.

Plant protection measures is the essential component of farming which play important role in saving the crops from diseases and insect-pest, therefore agricultural extension have a big role to play in finding the solution and providing it to the end users to get the technology disseminated at the earliest possible time with appropriate application, for which a scale was developed to measure the attitude of farmer towards plant protection measures based on Likert‟s techniques.

Pulses are important for the nutritional security point of view of the cereal based vegetarian diet of large scale of country. India is the largest producer, consumer and importer of pulses in the world. It has been projected that 32.0 M. tones of total pulse requirement for the burgeoning population of India, which will grow to 1.69 billion by 2050. To attain upto this level an annual growth rate of 2.2% is required. The demand for pulses continues to grow at 2.8% per annum.

The newest waste management technology is bioconversion using fly larvae converting organic waste to insect larval biomass and organic residue. Bioconversion is a practice of recovering resources while simultaneously limiting the amount of organic material affecting landfill behaviour. Several organisms have been used in this treatment process. Several studies have been done using the black soldier fly larvae to degrade organic material.

A. Sâu hại 1. Rệp son (Scale insects) : Là loại rệp có vỏ màu nâu. Loài rệp này thường bám vào lá để hút nhựa và thải ra chất độc làm hại cây. Do đó phải phòng trừ thường xuyên để hạn chế khả năng sinh sản của chúng ( loài này sinh sản rất nhanh và gây hại lớn cho vườn lan). Phòng trừ bằng cách tiêu diệt bằng tay hoặc dùng các thuốc như Regent, Lannate, supracide...theo nồng độ khuyến cáo trên bao bì, phun 1 tuần 1 lần cho đến khi tiêu diệt hoàn toàn. 2....
