Strawberry blossom weevil (Anthonumus rubi). The strawberry blossom weevil (SBW) is one of the biggest pest in strawberry farming. It occurs every year and it is spread to the entire growing area in Sweden. It causes important yield loss and is a serious pest in conventional and organic strawberry farming. Non treated fields can results in 50% of the flower buds damaged and significant yield loss (Svensson, 2002). Biology The Strawberry blossom weevil, Anthonomus rubi (Herbst), is a small black…

The housefly, Musca domestica L. has a worldwide distribution and is prevalent wherever insanitary conditions abound. The most important public health concern is the potential of houseflies to transmit a large number of pathogens including microorganisms for diseases viz. typhoid, cholera, bacillary dysentery, diarrhoea, tuberculosis, poliomyelitis, anthrax, yaws etc. and many parasitic worms 1-5. The control of Musca domestica is therefore important not only for human health but comfort as well…

Case Study 1 1. Feliway is a synthetic analogue of the F3 fraction of the feline facial familiarisation pheromone, administered as a spray or as a plug-in diffuser (Bowen & Heath, 2005). Pheromones are detected by the vomeronasal organ, binding to pheromone-binding proteins in the olfactory tract, altering affective state via limbic system stimulation (Landsberg et al., 2013). Feliway diffusers provide reassurance to cats in stressful situations and decrease stress-related behaviours such as…

One of the most fearful times of a person life is around the preschool age. At that age, children already start to learn about social and physical…

“After emerging from brumation, the red-sided garter snakes start mating. The males awaken and come out of the cavities first to prepare for the mating process. On the other hand, the female snakes give off a sex-specific pheromone to attract a large number of males. This often leads to the formation of a mating ball in which the male snakes compete to secure the breeding rights. After copulation, the female looks for food and the proper place for giving birth. They are ovoviviparous…

Commonly, sexual selection changes with the seasons and level of development of an organism. “Seasonal changes in pheromone-detection ability and olfaction sensitivity over the reproductive cycle have been observed in mammals, birds, and teleost, but such seasonal shifts in the visual system are less well-developed” It has been hypothesized that three-spine sticklebacks, Gasterosteus aculeatus, are more sensitive to red during the summer than the winter, which could be linked to the desire to…

gypsy moth damage and watered during dry periods to prevent additional stress. Tree bands can also be added in late May. These sticky wraps trap female gypsy moth caterpillars as they hike up and down your tree to lay their eggs. Also, the natural pheromones of the trapped females will attract males as well. The combination of egg mass removal, insecticide application and installation of sticky bands will go a long way in reducing injury level to high-value landscape trees. After all, an…
