Initial Discovery

Abstract After its initial discovery in California in 2008, Drosophila suzukii Matsumura has become one of the most important invasive agricultural pest insects across climate zones in much of Asia, Europe, North America, and South America. Populations of D. suzukii have demonstrated notable behavioral and physiological plasticity, adapting to diverse environmental and climatic conditions, interspecific competition, novel food sources, and potential predators. This adaptability and plasticity have enabled rapid range expansion and diversified niche use by D. suzukii, making it a species particularly suited to changing habitats and conditions. This article reviews factors and evidence that influence plasticity in D. suzukii and promotes this species’ invasiveness.

Chemical Pesticides

Background: Red pumpkin beetle, Aulacophora foveicollis (Coleoptera: Chrysomelidae), is a serious agricultural pest of cucurbit plants. Chemical pesticides have been in practice for many years to control the pests. Recently, the plant essential oils were formulated as nanoemulsion, have gained interest for their effectiveness and eco-friendly nature. The current study was aimed to assess the efficacy of Mentha piperita nanoemulsion against an agricultural pest A. foveicollis. Methods: M. piperita essential oil was analyzed by GC-MS technique. Ulrasonication method was used to formulate the nanoemulsion. The stable nanoemulsion was investigated and characterized by DLS. The efficacy of the nanoemulsion was screened against the pest of cucurbits, A. foveicollis at different concentrations and compared with its own bulk emulsion. Result: In GC-MS technique, menthol was found to be the major component with the highest percentage of 16.47 and the nanoemuslion was prepared in different ratios comprising of peppermint oil, surfactant, acetone and water. The stable nanoemulsion was investigated and characterized by DLS with mean droplet size of 10.84nm, PDI was 0.1 and zeta potential was -45 mv, altogether proves to be the good stability of nanoemulsion. The Bioassay was conducted for about 96 hours and the highest mortality was recorded in the nanoemulsion than the bulk emulsion. The resulted LC50 value of nanoemulsion is 22.38% v/v is found to be effective than the LC50 value of bulk emulsion is 87% v/v, respectively. Thus, from the results obtained the nanoemulsion was found to be highly significance than that of the bulk emulsion. So, nanoemuslion may be used as an eco-friendly agent against the agricultural pest management.

Exhaustive List

Abstract Agricultural imports are the primary pathway for the introduction of exotic insect pests. The invasion records of exotic insect pests are also influenced by the lag time before detection and saturation caused by the limited species pool of potential invaders. We compiled an exhaustive list of exotic insect species in mainland Japan and tried to evaluate the connection between the commodity types of agricultural imports and insect types of agricultural pests, in addition to the effects of lag time and saturation. We found that lag time was prominent when all pest types were merged into one group, whilst saturation always existed when we divided the records into the four agricultural pest types. Saturation was especially prominent in stored product pests because this group contained many cosmopolitan insect pests that could have easily inhabited the newly built mills throughout Japan in the 1950s. We suspect that the saturation effect was masked by admixture amongst pests with different saturation patterns. Our findings indicate that all commodities, i.e. flowers, fruits, vegetables, cereal and timber, contributed to the invasion of pest insects as potential pathways. However, it was unclear if certain items had comparatively greater significance in this process.
