“…Black linen cloth was provided at the top of cages for egg laying and removed on each alternate day to harvest the eggs. The eggs were placed in black cloth (cover cloth) and fed on frozen Angoumois grain moth (Sitotroga cereallela Olivier) eggs [9]. After hatching (48 -60 hrs), individual 1 st instar larvae were sealed in 2 inches polypropylene transparent straw with three pin aeration holes to avoid the cannibalism.…”

“…Regardless of advances in insect management technologies, use of insecticides is still a common practice worldwide for the control of various insect pest populations [8]. However, insecticides have been also reported with numerous demerits, such as the emergence of secondary pest populations, resurgence of various pests, producing resistant pest populations, and lethal effects on the natural enemies cohabiting in agroecosystem [7,9]. Based on the importance of C. carnea eggs and pupae, tolerance to insecticides may play a vital role to eliminate the pests which are usually escaped from chemical control [1].…”

The reported high loss mortality rate of green lacewing, (Chrysoperla carnea) have been attributed to diverse factors including unattended use of insecticides. Since chemical control is one of a significant practice to manage insect pest in cotton. However, this kind of practice may impair the natural control provided by generalist predator C. carnea. Although, natural control adoption is limited in crops, area and season due to wide-spread use of insecticides but presence of resistance potential in C. carnea may improve the design of solid IPM strategies. Herein, we aimed to assess the toxicity of four insecticides to two strains of C. carnea (viz. laboratory reared and field collected adults) and to evaluate their resistance potential by calculating their resistance ratio. LC 50 was calculated at 24 h following topical application administered when the adults were 3 days old. Control adult mortalities were less than 10% at 24 h. The LC 50 values (µl mL -1 ) for laboratory reared strains of each tested insecticide were: acetamiprid, 0.0064; bifenthrin, 3.75; chlorpyrifos, 0.067; and profenofos, 0.052. The LC 50 values for field collected strains were 0.096 (acetamiprid), 34.8 (bifenthrin), 0.21 (chlorpyrifos) and 0.44 (profenofos). The toxicity of the test insecticide to C. carnea from more to least toxic was acetamiprid > profenofos > chlorpyrifos > bifenthrin. Field collected strain possessed 15 (acetamiprid)-, 9.28 (bifenthrin)-, 3.13 (chlorpyrifos)-, and 8.5 (profenofos)-fold more resistance than the susceptible population. These results are pretty worthwhile for integration of C. carnea in IPM programs, impairing with insecticides.

“…Preetha et al (2009) found 81.5% viability of Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) eggs treated using the organophosphorus monocrotophos (2 mL c.p./L of water); Gandhi et al (2005) showed that the use of imidacloprid (350 g c.p./L of water) and endosulfan (350 g c.p./L of water) exhibited viabilities of 43.5 and 55.0 %. The toxic effects of fifteen insecticides, at their highest recommended concentrations for wheat crop, were evaluated by Pasini et al (2018), who concluded that only etofenprox and imidacloprid + beta-cyflutrin reduced the viability of C. externa eggs in 40 and 70%. Although the use of insecticides allowed a large number of eggs to hatch, only 22.5, 27.5, and 12.5% of larvae survived from the eggs treated using chlorpyrifos, profenofos/lufenuron and triazophos/deltamethrin, respectively (Table 3).…”

Given the importance of green lacewings as agents of biological pest control, the present study aimed to evaluate the toxicity of insecticides used on coffee crops on the eggs and larvae of Chrysoperla externa. The insecticides tested were (g or mL a.i./L) chlorpyrifos (2.25), cartap hydrochloride (1.66), pyriproxyfen (0.33), profenofos/lufenuron (1.33/0.13), fenpropathrin (0.40), triazophos/deltamethrin (0.70/0.02) and zetacypermethrin (0.05). The insecticides, when applied directly on the eggs, caused no adverse effects on the duration of the embryonic period. After the application of triazophos/deltamethrin, pyriproxyfen, profenofos/lufenuron and zetacypermethrin, a reduction in egg viability was induced. The insecticides triazophos/ deltamethrin, chlorpyrifos, and profenofos/lufenuron reduced the survival of newly hatched first instar larvae from treated eggs. The first instar larvae that were treated directly were sensitive to the effects of the products used, with the effect of triazophos and chlorpyrifos/deltamethrin being high. The survival of the second instar larvae was reduced by zetacypermethrin, fenpropathrin, profenofos/lufenuron, and cartap hydrochloride. The products chlorpyrifos and triazophos/deltamethrin also did not allow second instar larvae survival. For treated third instar larvae, chlorpyrifos and triazophos/deltamethrin allowed survival of only 20.0 and 57.5%. Eggs and larvae of C. externa showed sensitiveness to insecticides chlorpyrifos and triazophos, being needed more studies in semi-field and field conditions for the confirmation or not of the toxicity aiming the conservation of this predator specie on the coffee agroecosystem.

“…Selective phytosanitary products may intervene in the development and survival of entomophagous insects and entomopathogenic microorganisms [ 23 , 24 , 25 ]. There are reports of the negative effects of pesticides at all stages of development of C. externa [ 26 , 27 , 28 , 29 , 30 ]. The selectivity of the entomopathogenic fungi concerning green lacewings raises the potential for biological control by the synergism and conservation of natural enemies in the agroecosystem.…”

We aimed to evaluate the selectivity of entomopathogenic fungi to larvae of Chrysoperla externa (Neuroptera: Chrysopidae). For this purpose, Beauveria bassiana (strain ESALQ PL63), Metarhizium anisopliae (strain ESALQ E9) and Metarhizium rileyi (strain UFMS 03) were assessed at different concentrations (1 × 107, 1 × 108 and 1 × 109 conidia mL−1). The control treatment consisted of distilled water and Tween80 0.01. The treatments were applied with a Potter spray tower using two different methodologies: direct application (DA) and dry film (DF). Up to 96 h after application, no treatment provided a larval mortality above 3%. After 120 h, only B. bassiana induced significant mortality in all instars, with rates of 26%, 17% and 10% for first, second and third instar larval periods, respectively. There was no difference regarding to the application method or concentration of conidia. The percentage of individuals that revealed changes in the length of the larval and pupal periods varied among different treatments with entomopathogenic fungi and control treatments, application methodologies and concentrations. Despite B. bassiana revealing a higher mortality than M. anisopliae and M. rileyi on larvae of C. externa, these three entomopathogenic fungi may be used in association with C. externa for sustainable pest management.
