Understanding the biosecurity risks that invasive alien insect pest species currently ravaging forest trees pose is of great importance to forest ecosystems and health. This problem has posed significant challenges to researchers, relevant stakeholders, policy makers and national biosecurity agencies worldwide. This study gives an overview of the top 15 suspected insect pest species most likely to invade or have already invaded forested habitats in order to disrupt ecosystem services and biodiversity within the borders of Nigeria through borderline states (Gombe, Jigawa, Borno, Yobe, Sokoto, Cross River and Lagos). For Nigeria as a whole, all of these top 15 pest species have already established, with identified intra- border line states having no significant effect on severity of invasions ( F1,6=0.07, P=0.910) when compared to identified inter-border line states. This study concludes that the immediate biosecurity risks from already identified invasive insect pests are greater from outside country (inter) borders of Nigeria than within state-to-state (intra) borders of Nigeria. Our findings have potentially significant implications for immediate implementation of national biosecurity forest policy Acts in compliance with Cartagena and Nagoya protocols, emphasizing the need to initiate and implement biosecurity measures simultaneously with any ongoing trans-national border interventions.

The cases of coronavirusdisease 2019 in children have been increasing with the ongoing pandemic.The finding suggests children have mild symptoms and a short course of the disease. Angiotensinconverting enzyme-2 mediates entry of the virus into the cell, the combination of virus and ACE2 leads to an increase in activity of angiotensin II, resulting in acute injury to lungs, myocardium and other organs. The infection causes down-regulation of ACE2 expression. The ACE2 plays an important role in the infection progression and clinical characteristics of COVID-19. Works on ACE2 and virus spike protein have future prospects of strategic information on prevention, management as well as vaccine development.

Phytopathogenic fungi decrease crop yield and quality and cause huge losses in agricultural production. To prevent the occurrence of crop diseases and insect pests, farmers have to use many synthetic chemical pesticides. The extensive use of these pesticides has resulted in a series of environmental and ecological problems, such as the increase in resistant weed populations, soil compaction, and water pollution, which seriously affect the sustainable development of agriculture. This review discusses the main advances in research on plant-pathogenic fungi in terms of their pathogenic factors such as cell wall-degrading enzymes, toxins, growth regulators, effector proteins, and fungal viruses, as well as their application as biocontrol agents for plant pests, diseases, and weeds. Finally, further studies on plant-pathogenic fungal resources with better biocontrol effects can help find new beneficial microbial resources that can control diseases.

Alien Insect

Invasions of alien insect pests often result in dramatic shifts in the entire ecosystems brought about by severe outbreaks of the pests exploiting new and frequently defenseless host plants. The explosive population dynamics of invasive insects often enable them to outcompete native pest species and alter both the abundance and diversity of communities of their natural enemies. These impacts are probably the most conspicuous and notorious when the invaded host plant is a key commodity crop and the invasive pest an aphid (Hemiptera: Aphididae). Aphids have a remarkable ability to overwhelm their plant hosts extremely rapidly owing to their parthenogenetic reproduction (i.e., daughters are clones of their mothers), live birth, and telescoping generations (i.e., the offspring of unborn aphids are already developing within their bodies). Aphids also attract exceptionally diverse communities of predators and parasitoids, which are strongly attracted to the volatiles emitted from plants attacked by aphids, albeit the natural enemies' attraction to invasive aphids often requires a period of adaption to recognize a new prey. Hence, when new species of aphids invade a new agroecosystem, their presence frequently creates an ?ecosystem earthquake' that can have profound implications for long-term stability of the system most directly affected by the invasive aphid as well as neighboring crops.
