Hello there, this is my first post at this unique forum, but I am sure glad I bothered to sign up a while back. I have had Dubias and Orangehead colonies for several months now and keep them directly next to each other. I tend to leave them alone for the most part as I am not feeding off them yet, just leting them build up numbers. Well, the other day I decided to check on them, feed &water, ect.... When I pulled out the Dubias, they were doing great, yadda, yadda/// Then when I opened up the Orangeheads I noticed about 1/2 of my colony dead, no small roaches at all, and the ones that were alive were wandering around aimlessly and very very very slow.... Dying.... and taking 3-5-7+ days to die.... I use water crystals, my feed is a custom blend of catfood, dogfood, fish flakes and bought roach chow, and Flukers cricket crud....the dg foor being the main ingridient, between 2 brands it makes up 80% at least. I had neglected to offer fresh veggies for about a month, but I have them in a well tempered and humid area... gets between 75 - 95 down there in the basement. humidity ranges from 25% to 45% ...and I shoot a couple squirts of water in through the screen every/every other days or so... I did clean out their cage when I saw the deaths, and did find a little bit of mold on the food, but i have seen it in much worse shape and they were not affected. Let me describe the symptoms more. I am noticing the back part of the abdomen is swollen to a unusual plumpness on all the dying/dead bugs so I preformed a few necropsys... yuck man... but needed.. What I found was their anus seem blocked ( you know how easy it is to make them pee a little when picking them up if you give one a squeeze just a litle too much?? well, I had to really press and work at the dying ones to get anything to squirt out..). and upon disection of the abdomen, found HUGE amounts of frothy white guts,,, muck everywhere.... Now, lets move onto the behavior symptoms.. They are EXTREEMLY lethargic///// they congrigate around the water dish out in the wide open, and cling to the screen on the sides of the cage... they move very slowly, and the closer to death they get the less they seem to be able to move thier legs... Its been 3 days since I noticed this, and some males/fems are still hanging on after this long, barely able to crawl, little tiny jerks of the legs... I have even had to flip a couple over a few times... I have been keeping them very very humid since seeing them all ganged up on the watering dish. using a humidifyier right in the cage... All fresh food, some banana which they are not interested in at all after 3 days. gna remove it and try something else fresh. So, lets see what I could have done to cause this.... Temps.... I ran a pertable A?C unit in basement fr 2 days, and let the exhaust point in the direction of the bins,,,, both bins though, including my Dubias.... Also, I left the outside basement doors open a coupel nights, letting in cooler air,,, I do not believe it ever came close to 68...again, they live side-by-side with my Dubias (dubia colony started from 250 nymphs 3 months ago, first adults emerging now, and Orangeheads were just a 25Mixed feeder batch I let run wild and last time i checked on them were out-breeding my adult dubia colony of 20f/6m by x3-5 times, but I lost the adult dubia clony in a flood about 2 months ago...so all left was my 250 nymphs which are thriving, molting, maturing and otherwise super active and quick and 1 deadloss ... thats it..) ... So, some tepm fluctuations, humidity fluctuations... they had eated all thier young except 3-4 large nymphs, shown mild intrest in my custom mix....and drank water crystals... and I've got this slow agonizing and slowly paralizing deaths.. Anyone care to throw out an opinion?
BTW, i keep them just like everyone else... huge rubermaid bins, 3-6 ventholes, 10ish verticle egg cartons. Food is given from a self-feeding dish so I never run out n starve them, and I scatter it beneath thier egg crates....water is given in a rock-like watering dish with gentle sloping sides for ease of access. Sometimes, most times there is just the gel form of water available in the dish, no liguid what-so-ever.... but since I have been watering daily so there is an option to suck on the crystals, or drink around them..... I have seen little if any improvements since I found them and have been tending t them every few hours making sure I am offeringevery remidy I know, temp-humid-water-food ect.....
