Taschenbuch. Zustand: Neu. Neuware - During the last few decades, cole crops production are severely affected by diamondback moth (DBM), Plutella xylostella infestation as this insect developed multiple resistance to commonly used insecticides resulting in population outbreak, causing devastation and complete crop loss throughout the world. The use of manipulating integrated methodologies are reducing the host plant resistant and natural enemies and also increasing the production cost. The failure of all management strategies forced to study thermo regulatory, tritrophic relationship of development of DBM with host plant and environmental condition. The present monographs deals with the population dynamics and life table studies of DBM, estimation of thermal threshold level, and calculation of degree days at different temperature and host plants in laboratory and field conditions.…

Zustand: Hervorragend. Zustand: Hervorragend | Sprache: Italienisch | Produktart: Bücher | L'uso di diversi metodi di campionamento è utile per l'indagine sulla fauna di insetti della cipolla e per fornire una comprensione dei tripidi della cipolla, Thrips tabaci in relazione alle cultivar e ai fattori biotici e abiotici. Trentasei insetti e ragni appartenenti a 17 famiglie e 10 ordini sono associati alle cultivar di cipolla. L'individuazione precoce e il monitoraggio di T. tabaci possono essere effettuati utilizzando trappole appiccicose o campionamenti di piante. I fattori abiotici (temperatura e umidità relativa) sono i principali fattori che regolano la crescita della popolazione. I nemici naturali e altri insetti parassiti della cipolla sono correlati in modo non significativo con T. tabaci in condizioni di campo. La trappola blu e il campionamento delle piante sono i metodi migliori per determinare il livello di infestazione. Il livello di soglia economica potrebbe essere determinato dalle trappole adesive, ma necessita di ulteriori indagini. Le trappole adesive non possono essere utilizzate nella gestione dei tripidi sulla cipolla, ma solo per il monitoraggio dei tripidi.…
