“…Thirty h old embryos from females exposed to Dimilin for 12 to 48 h were active inside the eggs so it is apparent that eclosion is effected by physiological rather than mechanical means. The failure of fully developed insect larvae to emerge from Dirnilin treated eggs has been noted by Mulder and Gijswijt (1973), Moore and Taft (1975) and Wright and Spates (1976). Miura et al (1976) found that treatment of mosquito (Culex pipiens quinquefasciatus) eggs with Dimilin caused weakness of the chorion and interfered with the transverse line of dehiscence in the e g g case.…”

Studies of adult LD,, concentrations of Dimilin, an insect growth regulator which acts to inhibit chitin synthesis, are misleading when applied to arthropods which experience a terminal molt. The calanoid copepod Acartia tonsa Dana has a determinate number of molts after which no growth occurs and the necessity of chitin production is restricted. Survival of adult A. tonsa held for 5 d in concentrations as high as 1000 ppb Dimilin is not significantly (P < 0.05) different from the controls Fecundity of A. tonsa was not significantly (P < 0.05) altered by 1 to 4 d treatment with l , l 0 or 100 ppb Dimilin but the hatch of viable nauplii was reduced from 90+ % to less than 50 % in l ppb after 12 h of treatment and to less than 5 % in 10 ppb after 24 h of treatment. No viable n a u p l~i were produced by females held in either 1 or 10 ppb Dimilin for more than 36 h. When Dimil~n treatment ceased and the females were placed in seawater, the effect of Dimilin was not readily reversed No viable nauplii were produced by these females for at least the next 30 h after treatment ended

“…It also causes inhibition in the fecundity of female adults of several species of insect pests Taft and Hopkins, 1975;Crystal, 1978;Hajjar and Casida, 1979;Otten and Todd, 1979). Diflubenzuron applied to adult females caused a decrease in fecundity in the Mexican bean beetle, Epilachna varivestis Mulsant and Colorado potato beetle, Leptinotarsa decemlineata Say , and adversely affected egg viability in St. calcitrans and M. domestica (Wright and Spates, 1976). When 2 day-old female adults of the Japanese beetle, Oryzae japonica Willemse, were starved for 6 hours, and then allowed to consume 500 µg a.i.…”

“…One class of these compounds is employed as insect growth regulators. Application of diflubenzuron to adult females caused a decrease in fecundity in Epilachna varivestis Mulsant Coleoptera: Coccinellidae) and Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) (Holst, 1974;Fytizas, 1976) and adversely affected egg viability in Stomoxys calcitrans (L.) and Musca domestica L. (Diptera: Muscidae) (Wright and Spates, 1976). Philip and Loughton (1979) reported that haemolymph treated with DFB and cyclohexamide inhibited RNA and protein synthesis in the fourth-and fifth-instars of the L. migratoria.…”

The effects of sublethal doses (LD 10 : 1.00 ng/larva; LD 30 : 3.75 ng/larva) of chlorfluazuron on the amounts of testicular biochemical constituents of the common cutworm, Spodoptera litura (F.) was described. Chlorfluazuron was applied topically to newly ecdysed fifth-instar larvae under laboratory conditions. Sublethal doses of chlorfluazuron significantly reduced the amount of protein with no effect on carbohydrate and lipid. The relative proportion of the amounts of control testicular DNA was: 7.52± ± ± ±0.9 µg/mg at the day before adult emergence> 4.54± ± ± ±0.44 µg/mg at newly emerged adults> 3.52± ± ± ±0.49 µg/mg at 1 st day after adult emergence. Sublethal doses of chlorfluazuron significantly (p < 0.05) reduced the amounts of testicular, seminal vesicular and aedeagular DNA compared with the controls. Similar reduction was observed in RNA as found in DNA. Three peaks in ecdysteroid titres were observed during 80 to 208 h. Compared with the controls, all peaks were reduced in LD 10 or LD 30 treated testis as follows: 11.5 or 21%; 12 or 22%; 12.5 or 23%, respectively. Sublethal doses of chlorfluazuron reduced the ecdysteroid titres with no effect on its pattern. Sublethal doses of chlorfluazuron reduced the amounts of biochemical testicular constituents during the development of testes in S. litura.
