Summary: This study successfully assembled the genome of Psidium guajava and transferred genes to detect genomic loci linked to resistance. The findings suggest that the resistance may be regulated by mineral nutrients and phytohormone homeostasis or signaling. These findings contribute to the development of improved guava cultivars and hybrid rootstocks.

Summary: Predatory stink bugs are significant in controlling pests in agricultural and forest crops. In this study, the effectiveness of Brontocoris tabidus and Podisus nigrispinus in attacking and killing Thyrinteina arnobia larvae was evaluated. The results showed that B. tabidus had a higher success rate, possibly due to its larger mouthparts and higher amylase activity.

Summary: This study investigated the seasonality, interaction with the tea ecosystem, and parasitic impact of Cotesia ruficrus on the tea looper Hyposidra talaca. The population of C. ruficrus was found to be high during the pre-winter and spring seasons, coinciding with the increase in H. talaca population. C. ruficrus was observed to forage on flowers of Lantana camera, Moringa oleifera, and Clerodendron infortunatum associated with the tea ecosystem. The parasitic impact of C. ruficrus significantly affected the food consumption and development of H. talaca.

Summary: Host affiliation and entomopathogenic infections have significant effects on the population dynamics of the forest tent caterpillar (FTC). In this study, we investigated the tritrophic interaction among larval diet, larval microsporidian infection, and FTC life history traits. The results showed that microsporidian infection and larval diet individually affect the FTC life history traits, but there is no interactive effect between them.

Summary: This study determined the fertility life table parameters and behavior of T. howardi parasitizing P. xylostella. It was found that regardless of the natal host, the parasitoid responded to volatiles of both host species and exhibited the same rate of parasitism on P. xylostella. Therefore, T. howardi reared on the factitious host maintains its attraction and potential to parasitize P. xylostella, contributing to the biological control of this pest.

Summary: Predatory mites can protect their eggs from intraguild predation by staying close to oviposition sites and avoiding laying eggs near conspecific females. Adult female G. liturivorus were found to protect their eggs better when guarding them, compared to eggs not kept with their mothers. This shows that maternal strategies play a crucial role in reducing predation risk for vulnerable stages of species.

Summary: Many animals actively adjust their diet to maintain nutrient balance and improve performance. This study found that predatory mites have higher oviposition rates when feeding on a mixture of eggs from different prey species. They actively select prey to obtain a mixed diet and commute between different plant parts to find these prey.

Summary: Research has shown that omnivorous predators can induce plant defenses and the production of volatiles that can affect the behavior of other predators. This has important implications for biological pest control.

Summary: The intrinsic rate of natural increase (r(m)) is a key parameter in entomology and acarology, especially in studying the potential biological control agents of fast-growing pests. This study proposes a new method for estimating r(m) from partial life tables, allowing researchers to decide when to terminate life-table experiments based on the chosen precision. This method saves experimental time without compromising the reliability of the estimated growth parameter.

Summary: Damage by herbivores can modify plant structure and physiology, affecting the behavior and performance of future herbivores. This study found that necrosis caused by two mite species on coconuts facilitated access by caterpillars to the meristematic zone. The caterpillars primarily co-occurred with one mite species and preferred nuts with easy access to the meristematic region, regardless of mite presence. The presence of one mite species improved caterpillars' performance, but did not affect female moth oviposition preference. these findings suggest that mite damage plays a role in the infestation of coconuts by the moth.

Summary: Herbivores choose host plants based on plant quality, the presence of predators and competitors. The spider mite Tetranychus evansi suppresses plant defences and benefits later-arriving herbivores. The web produced by T. evansi prevents other herbivores from settling on the plant and benefiting from the suppressed defences. The whitefly Bemisia tabaci is negatively affected by the web of spider mites and prefers plants without the web.

Summary: Dispersal plays a crucial role in the dynamics and persistence of predator-prey metapopulations, with different dispersal strategies leading to variations in prey exploitation levels and influencing interaction times and numbers of dispersing predators. Experimental studies in the predatory mite Phytoseiulus persimilis suggest that timing of dispersal is a heritable trait that can result in quantitative differences in local predator-prey dynamics, providing opportunities to investigate the evolution of alternative prey exploitation strategies and select for predator strains with better biological control outcomes.

Summary: Biological pest control is crucial for sustainable agriculture, and predatory soil mites have the potential to be effective biocontrol agents. They are easy to rear, can be used against various pests, and can survive in unfavorable conditions. However, more research is needed to fully understand and utilize their biocontrol potential.

Summary: The effects of plant quality on the performance of a phytophagous mite were evaluated on intact plants and leaf discs. The mites produced fewer eggs on detached leaf discs than on intact plants. The oviposition rate of the mite was lower on plants infested with the inducer strain than on plants infested with the suppressor strain or uninfested plants.

Summary: Conservation biological control of pests can be achieved through crop diversification strategies. This study investigated the impact of intercropped plant species on the abundance and behavior of mites, as well as the dissimilarity of predator and herbivore mites in coffee crops. The results suggest that intercropped plants can attract and serve as a reservoir of predatory mites, enhancing pest mite biocontrol on coffee.

Summary: This study determined the spatial distribution of Leucoptera coffeella, a coffee crop pest, through geostatistical analysis. The study found that the density of L. coffeella was highest from July to November, positively correlated with maximum air temperatures and wind speed, and negatively correlated with minimum air temperatures and rainfall. Additionally, L. coffeella showed an aggregated distribution pattern starting at the edge of the crop. This information is valuable for timely management and control methods in coffee crops with a high incidence of L. coffeella.
