“…The impact of deltamethrin on parasitism varies between species of parasitoids 25,26 , but, in general, this insecticide presented low selectivity and high sublethal potential since its low doses can reduce the fecundity and longevity of parasitoids 27 . Deltamethrin reduced the parasitism percentage of Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) in Corcyra cephalonica Stainton (Lepidoptera: Pyralidae) eggs to 2.67% 28 and Eretmocerus mundus Mercet (Hymenoptera: Aphelinidae) on Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) nymphs to 30% 29 .…”

insecticides are the main method of controlling lepidopteran pests of eucalyptus plantations and those selective to natural enemies, such as the endoparasitoid Palmistichus elaeisis Delvare et LaSalle (Hymenoptera: eulophidae), are preferable. the objective of this study was to evaluate the selectivity and effects on biological parameters of the insecticide deltamethrin, registered for the control of defoliator caterpillars of eucalyptus, to the parasitoid P. elaeisis aiming the rational use of this insecticide and its compatibility with parasitoids. the experiment was in a completely randomized design. The treatments were the doses of 0.

“…According to Zantedeschi et al (2017), the insecticide lufenuron at the recommended dose to control caterpillars (100 g a.i. ha -1 ) had a deleterious effect on the reproduction of E. heros, reducing the number of eggs produced per female, similar to what was observed this work for the same species in a greenhouse.…”

“…This group of insecticides is normally characterized as selective products for nontarget organisms and have low toxicity for mammals (Khorshidi et al, 2019). Some IGR insecticides can cause negative effects on the reproduction of insects in the orders Coleoptera (Ávila & Nakano 1999;Nakano et al, 2018), Hemiptera (Furiatti et al, 2009;Zantedeschi et al, 2017), Orthoptera (Ghazawy, 2012), and Diptera (Djeghader et al, 2014). Thus, the morphological and physiological effects of IGRs on different groups of pests need to be evaluated to better understand the action of these products on the development of insects.…”

The Neotropical brown stink bug, Euschistus heros (F.) (Heteroptera: Pentatomidae), is an important pest that damages soybean, especially in the central-west region of Brazil. The effect of insect growth regulator insecticides on fourth-instar nymphs and adults of the neotropical brown stink bug was evaluated under laboratory and greenhouse conditions, respectively. In the laboratory, the insecticides (doses in g a.i. ha-1) novaluron (20.0 and 40.0), teflubenzuron (26.2 and 52.5), and lufenuron (20.0 and 40.0), in addition to the control (water), were tested on fourth-instar nymphs of E. heros and their development were followed to adulthood. Mortality, number of adults with and without deformities, and fecundity were determined. In a greenhouse, the effects of the same insecticides on the adult of the stink bug were evaluated by determining the fecundity and viability of the eggs laid. The fourth-instar nymphs of E. heros, when exposed to either dose of the tested insecticides presented mortality and insects with deformations, as well as reduced fecundity of females that reached adulthood. In the trial with adult E. heros, all tested insecticides reduced stink bug fecundity. In the same way, the viability of the produced eggs was reduced in all the chemical treatments, except for novaluron at the lowest dose tested, in which egg viability did not differ from the control treatment. Based on the obtained results, one can infer that the growth-regulator insecticides evaluated, although usually more suitable for the control of caterpillars, can interfere negatively in the development and reproduction of the neotropical brown stink bug, thus constituting a complementary alternative for the management of this pest.
