“…We conclude that the results of this work show that the reproductive state of males and females of A. calandrae (virgin or mated) does not affect the attractiveness to the volatile larvae or pupae with or without diet, but prior experience with the host alters the response of paired females. In applied context, the parasitoid learning could help to develop strategies for behavior manipulation and increase the impact of biological control (Meirelles et al 2009, Vargas et al 2017.…”

Chemotaxic Responses of Anisopteromalus calandrae (Howard) (Hymenoptera: Pteromalidae) to Odors of Larvae, Pupae, and the Diet of Lasioderma serricorne (Fabricius) (Coleoptera: Ptinidae)

Many hymenopteran parasitoids are known as biocontrol agents, such as Anisopteromalus calandrae (Howard) (Hymenoptera: Pteromalidae), which is known to parasitize larvae and pupae of coleopteran pests including Lasioderma serricorne (Fabricius) (Coleoptera: Ptinidae). The success of these parasitoids is related to their searching ability, which is mediated through chemical stimuli of the habitat, food, and the progeny of the host itself. This study aimed to assess the chemotaxic responses of A. calandrae comparing the reproductive state of the insects and the experience of wasp females, to different development stages (larvae and pupae) and the presence or absence of the host diet. The chemotaxic responses of A. calandrae individuals at 2 to 4 days old were assessed in a "Y" type olfactometer. Virgin and paired females (without and with previous experience of parasitism) were exposed to larvae of last instar contrasted with pupae and to the diet of L. serricorne. Both virgin and mated males were tested only for diet. Virgin females showed a preference for the diet in contrast to the larvae and to the pupae in contrast to the diet. Paired females without experience choose larvae over diet and made no distinction between pupae and diet. Experienced mated females showed preference for the host to which it had access before, instead of any other alternative option, indicating that there may be changes in the preference through learning.

“…By the end of this procedure, cups containing parasitoids were fixed in two release points in the center of the plot for 24 hours to allow the release of the remaining individuals. All parasitoids were 24-h old and had been previously fed ad libitum with honey [ 22 ].…”

We characterized the dynamics of mortality factors affecting immature developmental stages of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Multiple decrement life tables for egg and early larval stages of S. frugiperda in maize (Zea mays L.) fields were developed with and without augmentative releases of Telenomus remus Nixon (Hymenoptera: Platygastridae) from 2009 to 2011. Total egg mortality ranged from 73 to 81% and the greatest egg mortality was due to inviability, dislodgement, and predation. Parasitoids did not cause significant mortality in egg or early larval stages and the releases of T. remus did not increase egg mortality. Greater than 95% of early larvae died from predation, drowning, and dislodgment by rainfall. Total mortality due to these factors was largely irreplaceable. Results indicate that a greater effect in reducing generational survival may be achieved by adding mortality to the early larval stage of S. frugiperda.

“…Nectar and pollen represent, in many cases, the main sources of nutrients required by the adult parasitoids (Meirelles et al, 2009), as well as excreta from some hemipterous insect (honeydew) (Wäckers et al, 2008). The forestry species in the SPS showed abundant flowering and probably served as a food resource for the adult of Hymenoptera parasitoids species, Aphaereta sp.…”

The negative impact of livestock breeding on the environment has been mitigated through the combination of pastures and trees, characterizing the silvopastoral systems (SPS), an alternative to conventional pasture systems (CPS). The SPS provides environmental services, particularly the recovery of degraded areas and carbon sequestration. Furthermore, the complexity of the SPS can improve other environmental services, for example, enhance biodiversity and reduce pests through biological control. However, it is not clear the relationship between microclimate, pasture, trees, cattle, and invertebrate present in this environment. The purpose of this research was to characterize the macrofauna and determine the richness and abundance of invertebrates associated with dung patches of cattle raised in SPS and CPS pasture systems during two years in Brazil. As a result, we verified that the presence of trees in pastures alters the environment, notably through the reduction of solar radiation; decreases the wind speeds; attenuates the air and soil temperature, and diversifies the food supply, with the promotion of beneficial insect richness in dung patches of cattle. The diversity index of invertebrate fauna associated with dung patches in the SPS and CPS were respectively, 1.9 and 1.3. Besides that, the SPS contributed to higher densities of pupal parasitoids insects represented by Aphaereta sp. and Spalangia sp., the most important cattle ectoparasite controllers. In this way, we concluded that the integrated pasture systems are an essential tool for biodiversity improvement, especially the beneficial insects living in dung patches, which can contribute to reducing cattle ectoparasite infestations.
