概括

交生体的破坏影响了意大利本土的臭虫. 不同的感染率导致不同的死亡率和化结果,突出了物种对控制策略的特定反应.

科学领域:

昆虫学昆虫学是一门学科.
微生物学微生物学
虫害管理虫害管理虫害管理

背景情况:

像Halyomorpha halys这样的侵入性臭虫正在改变意大利本土的五虫害虫动态.
对H. halys有效的交生体向控制,对其他类害虫有潜力.
评估对非目标本地物种的影响对于农业生态系统健康至关重要.

研究的目的:

评估交生体破坏对与H. halys.同时出现的本地臭虫物种的影响.
调查不同类动物物种对共生体感染和对破坏的反应的变异性.
了解共生中断对综合性害虫防治策略的影响.

主要方法:

在使用16S rRNA基因测序的本地五体动物 (Carpocoris purpureipennis,Dolycoris baccarum,Graphosoma italicum,Palomena prasina,Rhaphigaster nebulosa) 中确定了共生生物.
在实验室条件下将抗共生体配方应用于卵体.
在第一阶段监测化率和蝶死亡率.

主要成果:

确定了与Pantoea结盟的共生体,物种之间感染率各不相同.
蛋质处理影响了D. baccarum和G. italicum的化.
在C. purpureipennis和G. italicum中,第一阶段死亡率增加,与共生体感染率下降相关.

结论:

五体共生中断会引起特定物种的反应,这与共生相互作用的强度有关.
响应的变化表明,控制策略必须考虑个体物种的生物学.
需要进一步的研究才能充分理解对农业生态系统的生态后果.

关键词:

潘托伊亚 (Pantoeaea) 是一个这是一只五毛动物 (Pentatomidae).V4 肠道心室非目标生物的非目标生物.二次性害虫是一种二次性害虫.共生破坏破坏共生.

Symbiosis

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
