“…dentata beetles need some time to adjust their “odor bouquet” to that of the host ant colony. After the pioneering discovery by Howard, McDaniel and Blomquist [27] of cuticular hydrocarbon mimicry in the termitophile stapylinid beetle Trichopsenius frosti and the subsequent discovery by Vander Meer and Wojcik [28] of the acquisition of the cuticular hydrocarbons by the beetle Martineziana dutertrei from its host ants Solenopsis richteri , extensive work has been published on chemical mimicry and camouflage in social insect colonies [29–34]. However Parmentier et al [35] found that in Dinarda maerkelii , the cuticular chemical profile deviates significantly from that of the host ant species.…”

The nests of advanced eusocial ant species can be considered ecological islands with a diversity of ecological niches inhabited by not only the ants and their brood, but also a multitude of other organisms adapted to particular niches. In the current paper, we describe the myrmecophilous behavior and the exocrine glands that enable the staphylinid beetle Dinarda dentata to live closely with its host ants Formica sanguinea. We confirm previous anecdotal descriptions of the beetle’s ability to snatch regurgitated food from ants that arrive with a full crop in the peripheral nest chambers, and describe how the beetle is able to appease its host ants and dull initial aggression in the ants.

“…On the other hand, it has been suggested that fatty acids, such as palmitic acid, possess insecticidal activity and inhibit the growth of the related species Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) (Farag et al 2011). Finally, the C28-aldehyde, octacosanal, suppresses aggressiveness in some insects (Mizuno et al 2018). The obtained results suggest that the major compounds identified in the chloroform extract of S. crotalarioides contribute significantly to the larvicidal and pupicidal activities.…”

Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) (fall armyworm) is a pest native to the Americas that affects a variety of crops. Its control is based on chemical insecticides. However, this practice has been associated with changes in the susceptibility of pests to various insecticides. The use of plant products represents an eco-friendly alternative. The objective of this work was to evaluate the larvicidal activity of the chloroform extract of Senna crotalarioides (Kunth) H.S. Irwin & Barneby (Fabaceae) to control S. frugiperda. The chloroform extract of S. crotalarioides caused significant larval mortality, and reduced pupal weight and adult emergence. The analysis by gas chromatography coupled with mass spectrometry (GC-MS) revealed the presence of 22 compounds in the chloroform extract of S. crotalarioides leaves, with the straight-chain aliphatic fatty alcohol 1-octacosanol as the main component. This study revealed that the leaves of S. crotalarioides synthesize long chain alcohols, which increased the mortality of S. frugiperda in its larval stage, including the pupal stage. The extract also caused a decrease in the S. frugiperda pupal weight. The potential use of the chloroform extract obtained from S. crotalarioides and its principal chemical constituent is proposed as a promising alternative to control S. frugiperda.

Para su control, se emplean insecticidas químico sintéticos. Sin embargo, esta práctica se ha asociado con la generación de resistencia del insecto a estos productos. El uso de productos botánicos representa una alternativa eco amigable. El objetivo de este trabajo fue evaluar la actividad larvicida del extracto clorofórmico de Senna crotalarioides (Kunth) H.S. Irwin & Barneby (Fabaceae) para controlar S. frugiperda. El extracto ocasionó mortalidad significativa de la larva. También se observó reducción de peso pupal y de emergencia de adultos. El análisis mediante cromatografía de gases acoplada a espectrometría de masas (GC-MS) reveló la presencia de 22 compuestos en el extracto clorofórmico de las hojas de S. crotalarioides, siendo el alcohol alifático de cadena lineal 1-octacosanol el componente mayoritario. Este estudio reveló que las hojas de S. crotalarioides sintetizan alcoholes de cadenas largas, los cuales ocasionan un incremento en la mortalidad en el estado larval e incluso en el estado pupal de S. frugiperda. También el extracto indujo la disminución del peso pupal. El uso potencial del extracto clorofórmico obtenido de S. crotalarioides así como de su compuesto mayoritario para controlar S. frugiperda se plantea como alternativas promisorias.

“…In return, the ants protect them against different types of natural enemies. Individuals lose this organ during the pupal stage, but instead start to produce cuticular compounds that supress attacks from the ants and make the pupae less prone to ant predation [42]. In this way, L. argyrognomon butterflies can pupate in ant nests where they are protected from natural enemies.…”

Antipredator strategies of the pupal stage in insects have received little attention in comparison to larval or adult stages. This is despite the fact that predation risk can be high during the pupal stage, making it a critical stage for subsequent fitness. The immobile pupae are not, however, defenceless; a wide range of antipredator strategies have evolved against invertebrate and vertebrate predators. The most common strategy seems to be ‘avoiding encounters with predators' by actively hiding in vegetation and soil or via cryptic coloration and masquerade. Pupae have also evolved behavioural and secondary defences such as defensive toxins, physical defences or deimatic movements and sounds. Interestingly, warning coloration used to advertise unprofitability has evolved very rarely, even though the pupal stage often contains defensive toxins in chemically defended species. In some species, pupae gain protection from conspecifics or mimic chemical and auditory signals and thereby manipulate other species to protect them. Our literature survey highlights the importance of studying selection pressures across an individual's life stages to predict how ontogenetic variation in selective environments shapes individual fitness and population dynamics in insects. Finally, we also suggest interesting avenues for future research to pursue. This article is part of the theme issue ‘The evolution of complete metamorphosis’.
