“…In the 1994/95 soybean season, a new species of Telenomus (Hymenoptera: Scelionidae) was found parasitizing eggs of A. gemmatalis in Lapa; this species was described by Polaszek & Foerster (1997) as Telenomus cyamophylax Polaszek. In 1998/ 99, T. cyamophylax was also collected in Fazenda Rio Grande.…”

“…Until 1997 there was only one report on the incidence of egg parasitoids in eggs of A. gemmatalis (Hohmann et al 1989). Polaszek & Foerster (1997) described Telenomus cyamophylax Polaszek, 1997 from eggs of A. gemmatalis andAvanci (1999) reported the occurrence of Trichogramma pretiosum Riley, 1879, T. rojasi Nagaraja &Nagarkatti, 1973 andT. atopovirilia Oatman &Platner, 1983 parasitizing eggs of the velvetbean caterpillar.…”

T. pretiosum and T. acacioi accounted for more than 80% of the parasitoids emerged each year, followed by T. atopovirilia, T. rojasi and T. lasallei, with less than 20% of incidence. Both the sex ratio and the mean number of parasitoids/egg did not differ among the species. Searching for A. gemmatalis eggs proved to be time consuming in comparison to the collection of eggs laid by moths inside the cages, which showed to be a useful method to provide qualitative estimates of parasitism in eggs of A. gemmatalis.

“…This has been the generally received wisdom among those surveying and collecting insects over the past five decades ( e.g ., Noyes, 2020). Most Telenomus species for which the hosts are known are relatively host specific, many known only from a single host species (Polaszek & Kimani, 1990; Polaszek & Foerster, 1997). If the host range of T. tetratomus is limited to a few species inhabiting forests, the need to search for hosts in either pine or broad‐leaved forests could explain a preference for green over yellow, the latter assumed to be more associated with open herbaceous environments with a diversity of flowering plants and the former with forest environments.…”

Dendrolimus pini can be a serious defoliator of pine trees in some European countries. The monitoring of this insect is important, but no single standardized capture technique exists for monitoring purposes. 2 A range of insect trap types (delta sticky, G-trap, Unitrap and cross-vane Unitrap), colours (green, red and white delta traps and yellow and green cross-vane Unitraps) and types of capture liquid (glycol and salt solutions) were tested to determine the most effective trap for D. pini monitoring. Trap colour (yellow and green) was also tested for beneficial Hymenoptera and Diptera. 3 The Unitraps and cross-vane Unitraps were the most effective trap types, but the latter trap that contained glycol solution was less effective than a dry trap. 4 Trap colour did not have any effect on the catches of D. pini, but yellow Unitraps captured more Diptera (Phoridae and Tachinidae) and Hymenoptera (Pteromalidae, Ceraphronidae and Braconidae) than green traps. In contrast, the egg parasitoid Telenomus tetratomus preferred green traps. Overall catches of beneficial insects were relatively low, except Phoridae. 5 The Unitraps are recommended for the efficient monitoring of D. pini unless other factors such as trap cost or remote monitoring locations justify the use of other traps.
