“…Adult parasitoid emergence from diafenthiuron treated pupae of E. formosa and E. eremicus was also found to be unaffected. Diafenthiuron was harmless to adults as well as pupae of both parasitoids irrespective of exposure periods (Javed and Matthews 2002). Diafenthiuron was safer to adults of Coccinellidae and Miridae and both adults and immature stages of predatory mites, Amblyseius andersoni (Chant) and Typhodromus pyri Scheuten.…”

Insecticides are unavoidable in pest management programs especially when the pest crosses Econimic Threshold Level (ETL). Nevertheless, often the plant protection products kill the natural enemy population making the pest to resurge and thus demanding more sprays. Therefore, insecticides used in IPM programs should be selective enough to spare the beneficials. Laboratory studies were conducted to find out the toxicity of imidacloprid and diafenthiuron to the eggs, larvae and adults of Chrysoperla carnea. Imidacloprid at the recommended dose of 0.28 ml/l caused 15.38% egg mortality, 26.67 and 33.33% larval mortality by ingestion and contact, respectively and 50.00% adult mortality. The egg mortality was about 15.38% and larval mortality of 23.33% and adult mortality of 26.67% was caused by diafenthiuron. Based on the classification given by IOBC/WPRS working group on Pesticides and non-target invertebrates, both the insecticides were classified as harmless to C. carnea, since the recommended dose caused less than 50% mortality in the laboratory conditions.

“…Diafenthiuron was very effective against diamondback moth (Ishaaya et al 1993;Lingappa et al 2004). Diafenthiuron is effective against sucking pests like Bemisia tabaci (Gennadius) and Amrasca biguttula biguttula (Ishida) in brinjal (Patel et al 2006), Trialeurodes vaporariarum (Westwood) (Javed and Matthews 2002), Myzus persicae (Sulzer) and Frankliniella schultzei (Tyrbom) in tomato (Scarpellani 2000), Scirtothrips dorsalis and Oligonychus coffeae (Nietner) in tea (UPASI 2005), and all sucking pests in cotton (Kranthi et al 2004). Since diafenthiuron is effective against both the cardamom borer, Conogethes punctiferalis Guenee and thrips, Sciothrips cardamomi Ramk., it is widely used in cardamom plantations (Stanley 2007).…”

In the context of complex field problems, compatibility of an efficacious insecticide with other agrochemicals normally used in the field is essential. In this view diafenthiuron, a novel insecticide which inhibits ATP synthesis, used widely for pest management in cardamom, was tested for its compatibility with agrochemicals viz., fungicides and nutrients normally used in the crop. The results revealed that all the chemicals tested were physically and biologically compatible with diafenthiuron by means of physical stability and phytotoxicity ratings in the field. But the bioefficacy study on Conogethes punctiferalis in the laboratory and bioefficacy studies in the field against Sciothrips cardamomi reveal that diafenthiuron is incompatible and should not be sprayed along with fungicides like mancozeb and copper oxychloride. Another study on the compatibility of diafenthiuron with antagonistic microorganisms of plant pathogens viz., Trichoderma viride and Pseudomonas fluorescens revealed that diafenthiuron had some inhibitory effect on the mycelial growth of T. viride. Diafenthiuron did not affect the growth of P. fluorescens and thus can be used simultaneously for the control of insect pests and seed-and soil-borne diseases.

“…However, beneficial organisms are in contact with these insecticides through direct exposure to spray droplets or spray residues on crop foliage,4 and, although it is generally assumed that many biorationals are compatible with biocontrol agents, their effects on the performance and efficacy of natural enemies are not well documented. In the few studies that have looked at biorational insecticides, it is mostly their lethal effects on beneficial organisms that were studied, and it would be important to verify the sublethal effects that insecticides could have on parasitoids and their hosts 5, 6…”
