The success of the harvest period will greatly affect agricultural output itself. Processing fields that still use traditional methods affects crop yields, cause effect yields is pests faced by farmers. Rice plant often interfere are insect pests. Based on background, in this study designed a monitoring system for traps and automatic midges to cope with rice plants from pest attacks using IoT (...

Fitness costs associated with Cry1F resistance in the European corn borer" (2017). Abstract Crops producing insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt) are widely planted to manage insect pests. Bt crops can provide an effective tool for pest management; however, the evolution of Bt resistance can diminish this benefit. The European corn borer, Ostrinia nubilalis ...

Pathogenic fungi are important natural regulators of insect populations. However, many attempts to harness their potential for pest control have met with comparatively minor commercial success. Studies on mechanisms of pathogenesis have yet to contribute to the development of more efficient mycoinsecticides, but new insights into the pathogenic process are laying the groundwork. Significant pro...

Surveys were conducted in 1994 and 1995 to determine the pest status of the American plum borer, Euzophera semifuneralis (Walker), in New York State stone fruit crops. These surveys indicate that American plum borer is the most important of the wood-boring insects infesting tart cherries and also is an important pest in peaches suffering from canker diseases. It is not prevalent in plums or in ...

Sirex noctilio F. (Hymenoptera: Siricidae) is an introduced pest of pines (Pinus spp.) in several countries in the Southern Hemisphere. Although S. noctilio is established in North America (first discovered in 2004), it has not been a destructive pest there so far, where forest communities more closely resemble those in its native Eurasian range—where it is not a pest. To investigate the influe...

Habitat heterogeneity is thought to affect top-down control of herbivorous insects and contribute to population stability by providing a more attractive microhabitat for natural enemies, potentially leading to reduced population fluctuations. Identifying the parameters that contribute to habitat heterogeneity promoting top-down control of herbivorous insects by natural enemies could facilitate ...

BACKGROUND Many behavioral responses to odors are synergistic, particularly in insects. In beetles, synergy often involves a pheromone and a plant odor, and pest management relies on them for the use of combined lures. To investigate olfactory synergy mechanisms, we need to distinguish synergistic effects from additive ones, when all components of the mixture are active. RESULTS As versatile ...
