Summary: This study investigated the interactions between Phaedrotoma scabriventris and Zaeucoila unicarinata, two potential biological control agents for Liriomyza sativae in melon. The results showed that a combination of these two parasitoids can effectively control the prevalence of L. sativae, and there are competitive and predatory interactions between them.

Summary: The study found that Megoura japonica is the most suitable prey for Eupeodes corollae, providing the shortest generation time, highest intrinsic rate of natural increase, maximum fecundity, and greatest flight ability. This provides a theoretical basis for utilizing the ecological service function of Eupeodes corollae.

Summary: This study examined the survivorship patterns of four conifer species in the forests of Murree hills, revealing that the survivorship curves for different tree species were close to Deevy type II curves, with higher mortality rates in old-aged trees and illegal logging as a major cause of tree loss.

Summary: There is a connection between cell size and ageing patterns and mortality rates, with organisms having smaller cells requiring more resources for plasma membrane maintenance, leading to accelerated intrinsic mortality. By rearing fruit flies with small and large cells through the use of rapamycin, it was found that small-celled flies had higher mortality rates in early adulthood.

Summary: The shape of mortality is essential for understanding biological processes, and entropy metrics are commonly used to quantify the distribution of mortality. However, these metrics have limitations and cannot distinguish between different survivorship curves, which may mask important macroecological patterns. Therefore, alternative metrics such as area under the curve are recommended for capturing the full range of variation in mortality curves in macroecological studies.

Summary: This study compared the reproductive and population parameters of the braconid Utetes anastrephae reared on two different hosts, Anastrepha obliqua and Anastrepha ludens. The results showed higher survival in females reared on A. obliqua, but higher fecundity and parasitism in females reared on A. ludens. The intrinsic rate of increase, mean generation time, population doubling time, and sex ratio were similar in both cohorts.

Summary: This study analyzed the characteristics of Aedes aegypti populations from different cities in Colombia, including lifespan, fecundity, and mortality. The study found that each population had unique features and patterns, which are important for determining the timing of insecticide application and surveillance.

Summary: This study aims to determine the influence of egg cluster size on the parasitism rate, reproductive, and demographic parameters of the egg parasitoid Ooencyrtus obscurus. The results show that O. obscurus has a weakly synovigenic behavior, with a high rate of pre-imaginal survival and longer pre-imaginal development time for females. A single female of O. obscurus is able to produce more than 3 female offspring in a generation time and can multiply its population 1.05 times a day. Comparing these results with the main egg parasitoid in the native area of the western conifer seed bug can provide insights for implementing a biological control program in Europe.

Summary: This study found the presence of Ixodiphagus hookeri in two species of ticks in the Slovak Karst, demonstrating its potential for controlling tick populations. Infected ticks had higher body mass, but parasite presence did not affect nymph feeding duration. These findings provide valuable insights for tick control research.

Summary: Atlantic herring has a complex population structure and displays various reproductive strategies. Mixing between spring and autumn spawning herring occurs on the spawning ground, with differences in reproductive traits observed. The high variability in reproductive investment within spring spawners suggests the co-occurrence of groups with different behaviors.

Summary: Studies have shown that migratory butterfly species have lower fecundity and delayed reproduction compared to non-migratory species. This suggests that a migratory lifestyle may come with a reproductive cost, while non-migratory species may be more favorable for reproduction.

Summary: In this study, the effects of feeding pollen, yeast powder, or sugar to Euseius nicholsi insects were investigated. It was found that yeast supplementation shortened the immature stages and increased oviposition rate. The expression of EnTOR gene and Vg genes in Euseius nicholsi was also analyzed, and it was observed that yeast supplementation promoted EnTOR gene expression, leading to increased Vg gene expression and fecundity.

Summary: In this study, scleractinian corals were tagged and tracked to measure their vital rates and competitive interactions. Despite being disrupted by a tropical cyclone, the data collected can still be valuable for researchers interested in coral ecology and population dynamics.

Summary: The olive fruit fly is a major pest in crop production, and the use of environmentally safer biological control methods is needed. The study found that the parasitization rates and biological parameters of the Muscidifurax raptorellus parasitoid were favorable for controlling the olive fruit fly.

Summary: This study presents a comparative analysis of life history data for chimpanzee populations in North America and Japan, revealing differences in survival patterns based on sex and region. Males generally exhibit higher mortality rates compared to females, with variation observed in first year mortality rates across different populations.
