In this study, the intraguild predation (IGP) and cannibalism of adult females of these predators were studied under laboratory conditions. Data revealed that in the absence of extra guild prey (T. urticae), the adult females of IG predator S. gilvifrons consumed more larvae or nymphs of IG prey species than IG predators of O. albidipennis or S. longicornis. Females of S. gilvifrons showed significantly a higher predation rate on heterospecific young and old nymph instars of O. albidipennis than on S. longicornis. Interactions of adults S. gilvifrons and larvae or nymphs of O. albidipennis or S. longicornis were highly asymmetric or unidirectional predation always being the IG predator. S. gilvifrons had stronger intraguild predator than O. albidipennis or S. longicornis. Intraguild predation could be considered mutual between O. albidipennis and S. longicornis but there is neither predation nor egg deposition occurred on young or old larvae of S. gilvifrons. The IG predator O. albidipennis showed higher predation rate on S. longicornis than on conspecific nymphs. Whereas, S. longicornis showed high predation rate on conspecific larvae. Females of S. gilvifrons provided with conspecific or heterospecific young and old larvae or nymphs were able to lay eggs when fed on S. gilvifrons, O. albidipennis and S. longicornis. Also, O. albidipennis and S. longicornis laid eggs when fed on conspecific or heterospecific young and old larvae or nymphs except when fed on larvae of S. gilvifrons as IG prey.

A total of 5 endemic grasshopper species and 2 subspecies belonging to 6 genera, 4 subfamilies and two families are listed from the Egyptian fauna: Crinita nigripes, Duroniella cooperi, Hyalorrhipis hyalinus, Pamphagulus bodenheimeri bodenheimeri, Sphingonotus balteatus latifasciatus, Sphingonotus niloticus and Sphodromerus atakanus. Another 10 sub-endemic species and subspecies in 3 families are listed. These were described from and are found only in Egypt and its neighboring countries. The endemic species and subspecies represent 6.5% while the sub-endemic species and subspecies are 9% of Egypt's total grasshopper fauna (N = 108 species). Most of Egypt's endemic and sub-endemic grasshoppers (90%) occur in the Sinai Peninsula and the Eastern Desert near the Gulf of Suez, while none occur in the Upper Nile Valley. Therefore, Sinai Peninsula is indicated as an important zone within Egypt where conservation efforts should be focused.

Some biological aspects of these populations were investigated under laboratory conditions at three constant temperatures (25, 27 and 30˚C).  The present results concluded that, the tested temperatures had main effect on stages durations, survival, adult emergence percentages, sex ratio, and fecundity of field SBW strain. Regardless the variety of cotton general trend of results indicated  that, the highest, moderate and lowest percentage of emerged moths were recorded at 25ºC, 30ºC and 27ºC, respectively. In addition, sex ratio were almost 1:1 but tend to females at 25ºC while in reverse  to male at 30ºC. At 27ºC sex ratio was 2♀: 1♂. Moreover, the fecundity of developed female from tested varieties recorded its highest values at 25ºC and sharply decreased at 27ºC.  While, at 30ºC, the emerged female lost its fecundity except females of Giza 45 deposited 169.0 eggs / female. Furthermore, the tested temperature may be reliable for one developed stage of spiny bollworm and not reliable for another of same population. Also, cotton variety had highly significant effect on the studied biological aspects on its pest SBW, as well as, the interaction between cotton variety and temperature. Regardless temperature, duration of larval stage was 29 & 25.0 days on cotton varieties Giza 45 and Giza 87 at 25ºC, respectively. Although, the respective duration of generation in both cases acquire 50 days and 39.1 days, the reproductive capacity of SBW of Giza 45 equal ten times of that when fed on Giza 87. In addition, the larval mortality was higher in population of Giza 87. Depending on the aforementioned conclusion, cotton variety Giza 45 is more susceptible to SBW infestation. The authors arranged the susceptibility of tested cotton varieties to SBW infestation in descending order as follow: Giza 45, Giza 88, Giza 87, Giza 92 and Giza 86. These composite relations need to further vision to study the insect ecology, biology, physiology and economic damage.

The present work aimed to study the impact of water dilution type (Nile and ground water) on physico-chemical properties, residual effect and bio- efficacy of insecticides against potato tuber worm Phthorimaea operculella (Zeller).The results showed that effect of Nile water on emulsion stability, wherever Roxy  diluted with Nile water gave cream layer 2 ml equal acceptable limits while with ground water gave cream layer 5 ml above limits. On the other hand, Malathate with two water types not gave any separation and creaming layer. The addition of Nile water increased surface tension in case of spray solution of Malathate, Runner, Roxy, Tracer, Penny and Proklame compared with ground water. Also, addition Nile and ground water to different insecticides increased foam volume with Proklame and Roxy amounted 53 and 49 cm and 8 , 17 cm , respectively, while other treatments  gave lowest foam volume. The PH values lie between very acidic in case of Roxy with N. water and G water (2.3 and 2.5) respectively and Malathate (3.9 with N water and 5.5 with G water). On the other hand , Runner and Penny recorded PH value ranged between 7.1 to 8.0 but Proclame  and Tracer recorded slightly basic (8.9 , 8.7) and (8.1, 8.1) with Nile water and ground water, respectively compared with Nile water and ground water alone without insecticides 7.4 and 8.0.

Concerning the efficacy of the tested insecticides in controlling P. operculella larvae differed significantly . Concerning effect of Nile and ground water on efficiency of insecticides on corrected mortality % on  P. opercullela larvae after two application. The results illustrated that corrected mortality percentage in treatments sprayed with pesticides mixed with nile water was higher (about two fold) than pesticides mixed with ground water in the two seasons, where proklame, Tracer, Pinny, Roxy proved to be the most effective materials. This reduction due to the high decrease of surface tension in ground water than Nile water. Also foam was high for proklame with Nile water and ground water represented by 53 cm and 49 cm respectively. In addition suspensibility percentage increased in Nile water than ground water, PH affected when addition Nile and ground water.      The obtained data concluded to preferred  use Nile water  in binary mixture with tested insecticides only and prevent use ground water.}, keywords = {S. tuberosum,P. operculella (Zeller),Insecticides,Phisico-chemical properties,Bio-efficacy and dilution water type}, url = {https://eajbsa.journals.ekb.eg/article_12877.html}, eprint = {https://eajbsa.journals.ekb.eg/article_12877_6c7598a88ea9b2db7903aff26b840006.pdf} } @article { author = {El-Lebody, Kreema}, title = {Biochemical , Histological Studies of Pectinophora gossypiella (Saund.)
