“…Fecundity peaks during a female’s lifespan have been reported in Aedes spp. and other arthropods, indicating that both longevity and fecundity are important in mosquito population dynamics [ 101 , 104 , 105 , 106 , 107 ].…”

Dengue, Zika, and chikungunya are arboviral diseases for which there are no effective therapies or vaccines. The only way to avoid their transmission is by controlling the vector Aedes aegypti, but insecticide resistance limits this strategy. To generate relevant information for surveillance and control mechanisms, we determined life cycle parameters, including longevity, fecundity, and mortality, of Colombian Ae. aegypti populations from four different geographical regions: Neiva, Bello, Itagüí, and Riohacha. When reared at 28 °C, Bello had the shortest development time, and Riohacha had the longest. Each mosquito population had its own characteristic fecundity pattern during four gonotrophic cycles. The survival curves of each population were significantly different, with Riohacha having the longest survival in both males and females and Bello the shortest. High mortality was observed in mosquitoes from Neiva in the egg stage and for Bello in the pupae stage. Finally, when mosquitoes from Neiva and Bello were reared at 35 °C, development times and mortality were severely affected. In conclusion, each population has a unique development pattern with an innate trace in their biological characteristics that confers vulnerability in specific stages of development.

“…The life table can provide a simple statistical summary, including the individual life expectancy and natality rate. In addition, the life table has a modifiable basic form that can be used for various data analyses such as mortality caused by various factors (Chen et al 2017;Naranjo and Ellsworth 2017;Herrero et al 2018;Janssen et al 2022).…”

Abstract. Listihani L, Yuniti IGAD, Ariati PEP, Pandawani NP, Selangga DGW, Temaja IGRM, Wirya GNAS, Sudiarta IP. 2023. Beneficial interaction between rice stunt virus and its insect vector Nilaparvata lugens Stal based on life table. Biodiversitas 24: 4690-4698. The brown planthopper (Nilaparvata lugens) causes direct and indirect damage as a stunting virus vector in rice. Insect vectors and viruses are closely related with respect to disease transmission to host plants. Thus, this research aimed to determine the specific relationship between a virus and its insect vector on the biology and demography statistics of viruliferous brown planthopper (BPH). Research method included the propagation of N. lugens and stunt virus inoculum, the observation of cohort, stadia duration and egg survival rates, imago life span, and N. lugens life table. The BPH life table was arranged with the jackknife method for two treatments: plants infected by stunt virus and healthy plants. The research result showed that plants infected by stunt virus can shorten the BPH nymphal development stage from instar 2 to instar 5, life cycle, preoviposition period, and double time. Plants infected by stunt virus did not influence the BPH hatching pattern but influenced the total number of hatching eggs. The next BPH generation of stunt virus inflected plants increased 29.51 times more from the previous generation, while on healthy plants, the next BPH generation only increased 27.51 times. Virus-infected plants generally appeared to be superior quality hosts for vectors compared to uninfected plants, thus enhancing vector life table and virus spread.

“…However, studies on reproductive parameters are essential for the development of control methods. The main survival strategy of insects and their establishment as pests in crops is reproduction (Cruz et al 2015(Cruz et al , 2016Bestete et al 2016;Kumari & Kaushik 2016;Guedes et al 2018;Herrero et al 2018).…”

Oviposition behaviour and electrophysiological responses of Alabama argillacea (Hübner, 1823) (Lepidoptera: Erebidae) to essential oils and chemical compounds

Alabama argillacea (Lepidoptera: Erebidae) is a cotton pest. It is considered the most important defoliator species. It is commonly controlled using non-selective synthetic insecticides. However, they cause adverse effects to the environment. Thus, there is a need for more sustainable forms of management. In this case, essential oils may be a promising alternative. They have proven effects against countless agricultural pests. However, there is still few information on the effects of essential oils against A. argillacea. The present work aims to evaluate the deterrent activity of essential oils of Mentha spicata, Litsea cubeba, Melaleuca alternifolia and Juniperus virginiana on the oviposition of A. argillacea and identify which compounds of these oils are responsible for this action. Oviposition bioassays were performed to test oils. Gas chromatography coupled with electroantennography (GC-EAD) was performed to identify constituents detected by A. argillacea. In oviposition bioassays, only the oil of M. spicata showed activity against A. argillacea. GC-EAD analyses of this oil revealed that three compounds elicited visible antennal responses, namely, limonene, carvone and (E)-β-caryophyllene. Bioassays testing these three compounds showed that only limonene elicited oviposition deterrence against A. argillacea. Hence, the findings suggest that the essential oil of M. spicata and, more specially, limonene may contribute to a more sustainable management of this important pest of cotton.
