This week we have four updates on papers that we have been reading. 1. An endemic sawfly in China 2. A study looking at pest-insects microbiome 3. Ceratocystis Wilt is southeast Asia 4. Web based diagnosis of banana pests
If you have a new paper about forest health in Asia then share it with us!
Interspecific Correlation between Cephalcia kunyushanica and Host Plant in Natural Forest in Kunyushan Mountains, China
In order to determine the propensity of Cephalcia kunyushanica (Hymenoptera: Pamphiliidae) to different forest types (host stand and host-non-host mixture stand) and the interaction between host amount and larvae density of Cephalcia kunyushanica. We investigated the mean insect density and stand types in 50 permanent plots in the Kunyushan Mountains, China. The results showed that seven kinds of pine species were determined as the host of Cephalcia kunyushanica in Kunyushan Mountains.
The microbiome of pest insects: it is not just bacteria
In this review, we present some key examples of how the different members of the microbiome, such as bacteria, fungi, viruses, archaea, and protozoa, affect the fitness and behavior of pest insects. Moreover, we argue that interactions within and among microbial groups are abundant and of great importance, necessitating the use of a community approach to study microbial–host interactions.
Ceratocystis Fimbriata: A White Listed Invasive Alien Species (Ias) Causing Wilt Disease On Acacia Mangium Plantation
Ceratocystis wilt is a serious and destructive disease of A. mangium. The first record in Southeast Asia was described in Indonesia where the disease caused significant mortality on young A. mangium trees (Tarigan et al. 2011). Silviculture and tree improvement studies were being extensively undertaken to reduce the incidence of the disease (Tjahjona et al. 2016). In Vietnam, the incidence of Ceratocystis wilt disease was recorded to infect up to 20% of A. mangium trees in some plantations. Furthermore, the disease has also reportedly been infecting A. hybrid (A. mangium ×A. auriculiformis). Other species of Acacia, in particular, A. crassicarpa and A. auriculiformis were also susceptible to Ceratocystis infection (Tarigan et al. 2011; Thu et al. 2016).ase of A. mangium. The first record in Southeast Asia was described in Indonesia where the disease caused significant mortality on young A. mangium tree.
Web-based expert system for diagnosing disease pest on banana plant
Development of computer technology inspires the creation of a computer application titled ‘Expert System in Diagnosing Web-Based Banana Plant Disease.’ The purpose of this research was to create a computer application that could be used by laymen, either banana farmers or the general public who wanted to know information about the ambon banana plant. In this system, the number of the program provided [this last bit about a number is unclear to me] would have given a significant contribution in building the program which may be useful for diagnosing pests and diseases in banana plants. There were 37 symptoms that resulted in five diagnoses caused by pests, namely leaf rollers, uret beetles, nematodes, fruit sca-bies and aphids and produced four diagnoses caused by diseases, namely fusarium wilt, bacterial / blood disease, banana dwarf and leaf spots.
